Detailed ways

1 shows a USB bridge migration cable according to a specific embodiment of the present invention. The USB bridge migration cable 100 is used to connect two personal computers (not shown). The USB bridge migration cable 100 of the present invention includes a USB bridge migration device. 110, the USB connection cable 102, the first USB connector 104 and the second USB connector 106, preferably, the first USB connector 104 and the second USB connector 106 are both USB A-type plugs (USB A- type plug connector), used to connect to a USB A-type slot (USB A-type receptacle connector) of the personal computer, and the USB bridge migration device 110 includes a first USB device controller 120 coupled to a second USB device via a bus 130 The controller 140, preferably, the first USB device controller 120 and the second USB device controller 140 are basically the same chip in terms of hardware structure, and the first USB device controller 120 includes a media access control circuit 122, an embedded flash memory 124 and USB physical layer circuit 126, and the second USB device controller 140 includes media access control circuit 142, embedded flash memory 144 and USB physical layer circuit 146, embedded flash memory 124 (or 144) is manufactured in the first USB device controller 120 (or In the second USB device controller 140), the capacity of the embedded flash memories 124 and 144 is small, for example, the size of 32K (K=10 ³ ) bytes, and the size of the entire die will be Slightly larger, but can get good control on cost.

Although the capacity of the embedded flash memory 124 and 144 is small, it is not very suitable for storing a large amount of data as a flash drive. According to a specific embodiment of the present invention, assuming that the first USB connector 104 is used to connect a first computer (not shown), and the second USB connector 106 is connected to a second computer (not shown), the user intends to connect The operating environment or part of the environment of the second computer is transferred to the first computer, and the operating system in the first computer can support the operation of the USB bridge migration cable 100 of the present invention, or be pre-installed in the first computer In order to cooperate with the application program and the driver program, if the operating system supports the operation of the USB bridge migration cable 100 of the present invention, this operating system will be a new operating system that will be released in the future. For example, Microsoft will launch the next generation The new operating system "Longhorn" Windows operating system works together with the USB bridge migration cable 100 of the present invention to solve the troubles of tedious setting and installation for users.

In this specific embodiment, before the USB bridge migration cable 100 of the present invention leaves the factory, the embedded flash memory 124 and the embedded flash memory in the first USB device controller 120 and the second USB device controller 140 The flash memory 144 respectively non-volatilely stores corresponding operating firmware programs. First, connect the first computer (not shown) to the first USB connector 104, and the first USB device controller 120 will initially receive the signal supplied by the two signal lines PWR and GND of the USB slot of the personal computer. Bus power (bus power), the first USB device controller 120 then loads the firmware program in the embedded flash memory 124 into the random access memory (not shown) in the media access control circuit 122, so that It cooperates with the processor (not shown in the figure, such as an 8051 processor) in the media access control circuit 122, and a reset (reset) command is issued by the personal computer and a link is established; in this specific embodiment Among them, as previously assumed, the first computer can support the operation of the USB bridge migration cable 100 of the present invention, for example, the corresponding application program or the next-generation operating system is installed, and the first USB device controller 120 reports to its manufacturer After the number (vendor ID, referred to as VID) and the product number (product ID, referred to as PID) are given to the first computer, the USB bridge migration cable 100 can be operated smoothly, and the difficulty to be overcome lies in the connection between the second USB device controller 140 and Operations between the second computer.

The second USB device controller 140 will report its configuration to the second computer during the link establishment stage. Preferably, the firmware program stored in the embedded flash memory 144 of the second USB device controller 140 tells The second computer has a logic unit number (LUN) of 1, and it is a multi-function USB device. The first function is an optical disc drive, and the second function is a USB bridge migration cable. line 100; the second USB device controller 140 reports to the second computer that it is an optical disc drive of the mass storage class (mass storage class), so that the second computer regards it as an optical disc, but in fact the memory space can be In the first computer, for example, in the hard disk or random access memory, or, also by specifying the file, such as a binary data file (binary datafile), such as an img file or a dat file, by The application program matches the designated file to operate as optical disc data, and the access command can be passed to the firmware of the first USB device controller 120 through the firmware in the second USB device controller 140, and finally handed over to the aforementioned first computer The application program or the operating system in the first computer is interpreted. Preferably, the application program or the operating system in the first computer provides a piece of program code for the second computer to execute and operate the corresponding application of the USB bridge migration cable 100 Programs and drivers also store CD-ROM auto-execution files that the second computer can recognize from the CD-ROM viewed by the first computer. For example, when the file name is autorun.inf, the CD-ROM automatically executes The file is used to execute the specified program code, causing the second computer to operate the second function as a USB bridging migration cable, to communicate with the USB bridging migration cable stored in the embedded flash memory 144 of the second USB device controller 140 The firmware programs of line 100 work together.

The foregoing description is to understand the operation of this embodiment, and further discussion is as follows: whether the USB bridge migration cable 100 of the present invention has directionality, and the flash memory of the first USB device controller 120 and the second USB device controller 140 Whether the firmware programs stored in 124 and 144 can be the same, so as to facilitate the continuous mass production of the entire USB bridge migration cable 100 production line and the user's convenience; The USB bridge migration cable 100 has no directionality. Based on the application environment of the above embodiments, after the first USB connector 104 is connected to the first computer, the first USB device controller 120 will report to the first computer about the USB bridge. The VID and PID of the migration cable 100, and the return LUN are 1 and multi-function, because the first computer has the application program of the USB bridge migration cable 100 or a new operating system that can support the USB bridge migration cable 100, so it can Identify its VID and PID to operate the USB bridge migration cable 100, and after connecting the second USB connector 106 to the second USB device controller 140, the same firmware program will report back to the second computer about the USB bridge migration cable The VID, PID, and LUN of 100 are 1 and multi-functional. Since the second computer cannot recognize the VID and PID of the USB bridge migration cable 100, it will preferably utilize the multi-function as described in the foregoing embodiment, and use the multi-function for the second computer. For two computers, the USB bridging migration cable 100 is an optical disc drive device to automatically install and execute the driver program and application program in the first computer, so that the second computer can normally operate the USB bridging migration cable 100, preferably The application then analyzes the working environment on the second computer, including installed applications, "my favorites" in the browser, email address book, and all existing Old emails in the second computer, etc., and migrate this environment to the first computer, or allow users to freely choose to migrate part of the operating environment to the first computer.

Those who are familiar with the technology can make various possible changes without departing from the spirit of the present invention according to the aforementioned disclosure. For example, the aforementioned second USB device controller 140 utilizes multiple functions to make the second computer automatically install Drivers and applications in the first computer can also report the USB bridge migration cable 100 as a single function, such as a CD drive, and after the automatic execution process is completed, the second USB device controller 140 sends a reset command , make it re-enumerate the bus (busenumeration), so that the second computer can identify its VID and PID and operate the USB bridge migration cable 100 .

FIG. 2 shows a flow chart of a computer operating environment migration method according to a specific embodiment of the present invention. In this method flow chart, it is desired to transfer the operating environment of the local (local) computer to a remote (remote) computer. The flow of the method The remote computer and the local computer in the figure can refer to the first computer and the second computer in the specific embodiment of FIG. It is suitable to operate on the above-mentioned USB device controllers. Start from step 200 and enter step 210. After the USB bus DC power supply is started, the firmware program is loaded and starts to operate. When the connected computer can recognize the VID of the USB device controller and During PID, proceed to step 215, successfully operate the USB bridge migration device with the USB device controller, otherwise proceed to step 220, indicating that this computer does not recognize that the USB device controller is a USB bridge migration device; in step 220, announce the first step The first function is a CD driver, and the second function is a USB bridge migration device to the connected computer; in step 230, the local computer automatically installs and executes the driver program and application program in the remote computer according to the first function to run the second The function is a USB bridge migration device. For example, the local computer maps a hard disk area or memory in the remote computer to an optical disc according to the first function, or can use a specified file, such as a binary data file ( binary data file), such as an img file or a dat file, and the specified file is operated by the application program as CD data, and an automatic execution file is stored in this CD, such as a file named autorun.inf, to automatically Install and execute the appropriate program code, causing the local computer to operate the USB device controller as a USB bridge migration device; in step 240, analyze the operating environment of the local computer, for example, which application software and browser "I" are installed In step 250, the operating environment of the local computer is transferred to the remote computer through the USB bridge migration device and the analysis results; finally, the process of the method is ended in step 260.

To further illustrate the first function and the second function described in FIG. 2 , it is declared as multi-function in USB that multiple EndPoints (EndPoints) on the hardware are required to collocate. For example, each media access controller in FIG. 1 has Ping-pong buffers to speed up the performance of data buffering. For example, a ping-pong buffer consists of a pair of 512-byte buffers. When the first 512-byte buffer is filled with data, it is moved to the next level. (stage) to send data, at the same time, another 512-byte buffer can be used to receive data to speed up data buffering; in order to include the first function and the second function when declaring the use of multi-function, the hardware should have two pairs of ping-pong The buffer, that is, two different terminal points, respectively correspond to the operation of two different functions.

Fig. 3 shows a flow chart of a method for migrating a computer operating environment according to another embodiment of the present invention. In this method flow chart, it is desired to migrate the operating environment of the local computer to a remote computer, which is preferred in this embodiment Utilize single USB function effectively, referring to the USB bridging migration cable 100 in the specific embodiment of FIG. The hardware structure and firmware program of the device 120 and the second device controller 140 are the same. It should be noted that those who are familiar with the technology, if the USB bridge migration cable 100 of the present invention is designed to have directionality, or use an external The switch determines its migration direction, etc., all of which do not escape the spirit category of the present invention. This specific embodiment starts from step 300. It should be noted that before the operation of the USB bridge migration cable 100, at least one of the computers connected to both sides has already installed the relevant driver and application program, or has been provided by the operating system. Enter step 310, first try to identify the VID and PID of the USB bridge migration cable 100; in step 320, declare to the connected computer as an optical disc drive; in step 330, the local computer does not recognize the VID of the USB bridge migration cable 100 And under the situation of PID, by the CD-ROM driver announced in step 320, use automatic execution to allow remote computer to install driver program and application program for the local computer, for example, because the CD-ROM driver announced in step 320 will let the local computer The computer sees the remote computer as a CD-ROM drive, and USB devices of the CD-ROM drive type support autorun, such as autorun.inf, so the local computer will automatically execute the file (such as autorun. .inf) to automatically install the driver and application program. After the installation of the driver program and application program, the local computer can fully support the operation of the next USB bridge migration cable 100. On the other hand, the remote computer starts The VID and PID of the USB bridge migration cable 100 are then known, so that although the USB bridge migration cable 100 is advertised to the remote computer as an optical drive, the remote computer can suppress the auto-installation of the auto-execute image file, or allow newer The version of the automatic execution image file is updated to an older version without error. On the other hand, if the computers at both ends are supported by the new generation operating system, both sides can determine the USB Generally speaking, the operation direction of the bridge migration cable 100 can be preset to migrate the older operating system environment to the newer operating system; in step 340, analyze the operating environment of the local computer, for example, including but Not limited to, all kinds of application programs installed, "My Favorites" in the browser, email address book, and all old emails stored in the local computer; The operating environment of the terminal computer, such as specially designed SCSI commands, can be migrated to the remote computer through the USB bridge migration cable 100, or, can be selected according to the operation of the user, selectively transfer the operating environment of the local computer A part is migrated to the remote computer via the USB bridging migration cable 100 ; then the process of the method ends at step 360 .

The embodiment of Fig. 3 is further described, illustrating that the present invention can also be implemented by using a single function and a special command, so the complexity and cost of hardware implementation can also be reduced. Corresponding to the foregoing description, each media access controller in Fig. 1 only needs A pair of buffers with a size of 512 bytes are used to implement a ping-pong buffer to implement this single function, instead of the multi-function as shown in Figure 2, separate hardware is required to implement different functions correspondingly; for example, The remote computer can recognize the USB bridging migration cable 100 initially by identifying the VID and PID. For example, the remote computer can periodically poll the USB bridging migration cable 100, but the local computer has not yet Before it is ready, the USB bridge migration cable 100 replies Not_Ready. Until the local computer issues the command to read the CD through the ATAPI command, the remote computer learns through regular inquiries, and matches the remote computer. The application program and the specified binary file simulate the CD and return the data to the local computer. Further provide the embodiment of virtual program code (pseudo code) for reference explanation below, this segment of program code is preferably embodied in the computer operating system of the next generation, for example in the Longhorn window operating system that Microsoft's next generation will release:

main()

{

//When the USB bridge migration cable is plugged into the USB port of the computer with the Longhorn operating system

while(Connection()＝＝0){ // Check if the computer at the other end is also connected

sleep(1000); // Delay for about one second

} // until the other end of the computer is connected to the USB bridge migration cable

SendAutorunImage(); // Send the autorun image to the other end

if(DoorClose()){ // Whether the other end is also Longhorn

if(SourceSystem()){ // Confirm whether it is the source

SendMigrationData(); // Migrate the job environment to the destination (the other end)

}else GetMigrationData(); // Get the working environment

}else // The other end is XP/2000/ME

GetMigrationData(); // Get the job environment from the other end

}

int Connection(void)

{

SCSI_Connection() //Issue a SCSI command via USB storage class.

//Return 0 if the other side is not connected or does not issue read autorun imagecommand.

//Return 1 if the other side is connected and issue read autorun image command.

}

void SendAutorunImage(void)

{

SCSI_BulkOutAutorunImage()//Issue a SCSI command via USB storage class.

//Send autorun image to the other side via bulk out pipe.

//Some autorun information may be stored in firmware code flash.

}

void SendMigrationData(void)

{

SCSI_BulkOutMigrationData()//Issue a SCSI command via USB storage class

//Send migration data to the other side via bulk out

pipe

}void GetMigrationData(void)

{

SCSI_BulkInMigrationData()//Issue a SCSI command via USB storage class

//Get migration data from the other side via bulk inpipe

}

int DoorClose(void)

{

SCSI_DoorClose()//Issue a SCSI command via USB storage to detect CD-ROM

//Return 0 if CD-ROM door opens(CD medium is not OK)

//Return 1 if CD-ROM door close(CD medium is OK)

}

The above embodiment of the virtual program code is implemented with reference to the flow concept of FIG. The program operation process is shown in Figure 4. It begins at step 400. Assuming that the Longhorn operating system (referred to as Longhorn computer) is installed on the remote computer, the above virtual program code is preferably included in the Longhorn operating system. The operating system of XP/2000/ME is preferably installed in the computer, and step 310 can be referred to, the VID and PID of the bridge migration cable of the present invention are identified in the Longhorn computer, and the bus enumeration is carried out to wake up the computer. The segment main program main() sends special SCSI commands via the USB storage class pipeline through the subroutine Connection() every about one second, asking (polling) whether the other end of the bridge migration cable of the present invention has been connected, and in addition On the one hand, the two controllers in the bridge migration cable of the present invention return a value of 0 if the other end has not been connected or have not issued a read auto-execute image file, otherwise a value of 1 is returned to detect Whether to connect to the local computer, it is as in step 410.

Confirm at Longhorn computer that the bridge migration cable of the present invention is also connected to the other end computer to complete bus enumeration, and this end computer also sends ATAPI to read the command of automatic execution image file, and Longhorn computer will be stored in hard disk by subroutine SendAutorunImage (). The specified binary file, such as image file or data file, etc., is output to the other end computer through a large number of output pipelines (bulk out pipe), in response to the command of the ATAPI reading automatic execution image file, which is as in step 420 ; Wherein, part of the data volume of the automatic execution image file can be non-volatilely stored in the flash memory in the bridge migration cable, preferably, non-volatilely stored in the USB controller in the bridge migration cable In the built-in flash memory, for example, the optical drive that is restored by the USB controller as a mass storage device, and the information such as the TOC (table of content) that will be queried by the host (host) can be stored in the bridge migration In the USB controller in the cable, to speed up the response speed of the bridge migration cable, the TOC data includes information such as the type of the optical disc and the start address of the track.

The Longhorn computer can use the value returned by DoorClose() to determine whether the other computer is also a Longhorn operating system, because only computers with a new generation of operating systems or corresponding running applications are stored with a specified automatic execution image file. , the status of its DoorClose () will be allowed to reply and be set to 1, which means that there is a CD in it for the other end to issue an order to read the automatic execution image file.

If both ends are Longhorn operating systems, SourceSystem () can allow the user to select as the source or destination through the application program, or select the migration method and migration content of the operating environment, which is as in step 420, or by the operating system Version or installation date, preset the migration direction of the operating environment; GetMigrationData () is to request the operating environment from the other end, as shown in step 440; and SendMigrationData (), allows the Longhorn computer to transfer the operating environment (or migration data, migrationdata ) is sent, as shown in step 450, and finally in step 460, the flow of the method is ended. The last section of the main program in the above Longhorn computer operating system can directly obtain its operating environment under the condition that the other end is judged to be an old operating system by DoorClose().

The above description is to facilitate those skilled in the art to have a better understanding of the present invention, and is not intended to limit the present invention. For example, the judgment of DoorClose () and SendAutorunImage () (transmitting the automatic execution image file) can be changed to Check the version of the operating system or application program, and then allow the newer automatic execution image file to update the older automatic execution image file. Many possible changes should still belong to the scope of the invention of the present invention.

With respect to the main program related to the operation of the bridge migration cable of the present invention in the above Longhorn operating system, the specific embodiment of the firmware program corresponding to the operation in the bridge migration cable is also given below to facilitate understanding of the implementation and operation of the present invention, but It is not intended to limit the invention in this way:

int DoorClsA，DoorClsB; //Reset to 0 when bus reset or hardware reset occurs

int EnumA, EnumB; //Reset to 0 when bus reset or hardware reset occurs

//Set to 1 when enumeration completes

int ReadCmdA，ReadCmdB; // Reset to 0 when bus reset or hardware reset occurs

// Set to 1 when reading a CD-ROM image

int ConnectionA(void) //Respond to the SCSI_Connection() sent by Longhorn

{

if(DoorClsA==0)

DoorClsB=1;

if(EnumB==0) return 0; //Check if the other end has completed enumeration

if(ReadCmdB＝＝0) return 0;//Check whether the other end sends ATAPI to read the automatic execution image file command

else return 1;

}

int ConnectionB(void) //Response to SCSI_Connection() issued by Longhorn

{

if(DoorClsB==0)

DoorClsA=1;

if(EnumA==0) return 0; //Check if the other end has completed enumeration

if(ReadCmdA＝＝0) return 0;//Check whether the other end sends ATAPI to read the automatic execution image file command

else return 1;

}

int DoorCloseA(void) //Response to SCSI_DoorClose() issued by Longhorn

{

return DoorClsA;

}

int DoorCloseB(void) //Response to SCSI_DoorClose() issued by Longhorn

{

return DoorClsB;

}

The above shows that special SCSI commands issued by the Longhorn computer are properly responded to by the firmware. For example, the SCSI_Connection() command issued by the Longhorn computer preferably has the firmware check whether the other end has completed the bus enumeration and issue the ATAPI read automatically. Execute the image file command before responding to complete the connection, allowing the Longhorn computer to jump out of regular inquiries and send out the image file for automatic execution.

The following also give an example of the automatic execution image file embodiment in Longhorn, so as to facilitate understanding of the implementation and operation of the present invention, but do not intend to limit the present invention with this:

AutorunImage

main()

{

if(OSVersion()==LONGHORN) //Only executed on XP/2000/MEexit(0);

else SendMigrationData(); //Send migration data to the other side

}
