Description of the Invention: [Technical Field] The present invention relates to a universal serial bus (USB) host control device, which refers to a USB host controller built in a chipset and a single USB The host controllers collectively provide a USB host control device for the corresponding USB transmission interface. [Prior Art] Connectors are widely used in the connection of electronic devices and their peripheral components, and their development and derivation of demand have often developed different specifications and specifications every other time. Among them, the specifications and specifications usually require a corresponding device or circuit design. The aforementioned connectors, such as USB (Universal Serial Bus, USB), are the most widely used applications in today's computer industry and (four) sex electronics. The channel can be used to connect various peripheral devices, such as keyboards, mice, and flash drives. , card reader, digital machinery, personal number (four), wisdom _ mobile phone materials. Plug and play and making 2 convenient are also the biggest factors that cause USB to be in the market. Nowadays, regardless of the surrounding business, electricity, manufacturers have developed for USB __, a variety of drive type and application The program is also available. For example, in the current development of the specification, the speed of USB 2 为 is ··, 201117015 and Cong 3.0 can reach 4·8 Gbps, and the data transmission speed is (10) 2 ... ... times. Compared to USB 2.0, USB 3. will be more energy efficient. In addition, the usb 3 〇 is down-stream and supports 脳2.0 devices. In other words, the USB 2.0 and USB 3.0 transmission interface can be provided simultaneously by the single-job 2/3. However, due to limitations in technology development, when USB 2.0/3.0 coexisting single-control benefits are used to connect USB 2.0 devices (such as chipsets with built-in USB2 q devices), there is insufficient compatibility and stability. If you want to improve compatibility and stability, you will have to invest a lot of cost and time to develop, so that the time to market will be extended. In addition, most of the traditional chipset has a built-in 2〇 host controller. If you use the USB 2.G/3.G coexisting single-control|| to connect the USB 2 domain, it is built into the chipset. The USB 2.G host control will be ineffective, causing waste of resources. It can be seen from the above that in the transition period between new and old specifications and specifications, how to make the connection H of non-standards and specifications compatible or shared under effective cost control, and ensure the stability of work, has become an important issue in the industry. . SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a USB host control device that utilizes a first-cylinder host lake built into a pattern towel (eg, Cong 2〇 host = manufacturing benefit) to provide compliance - the transmission side of the USB specification (eg, USB 2.G specification) and provides a second compliance with a single second USB host controller (eg, usb 3 〇 or B 2.〇/3·0 host controller) The transmission interface of the USB specification (for example, USB 3.0 201117015 specification) to solve the above problem. It should be noted that the following description only uses the first USB specification as USB2〇, and the second USB specification is USB 3·〇 as an example, but It should be understood by those of ordinary skill in the art that the architecture of the present invention can also be applied to the transition period of different specifications in the future, for example, the first USB specification is USB3 〇' and the second USB specification is USB4 〇, or the first usb The specification is USB 4.0, and the second USB is based on the situation of Cong 5, etc., which is limited by this embodiment. According to the embodiment, the USB host control device of the present invention comprises a chipset, a first USB host controller, and a first Second test host control The controller and a coffee connection first USB host controller are built in the chipset, and the first-level host control is in compliance with the -USB specification. The second Cong domain is electrically connected to the chipset, and the _USB domain Control (4) conforms to the second Cong specification, in which the second ship specification is different from the first USB specification. USB miscellaneous_feed-drain host controller and second USB host controller. In practical applications, the first USB mentioned above The specification can be a USB 2. 〇 specification, and the second USB specification can be used as a coffee maker. Thus, the present invention can provide compliance with the 2nd Q specification through the first USB host control wire built into the chipset. The transmission interface 'and use the early - third USB host controller to provide a compliant transmission interface' to reduce the number of chipsets built with Cong 2 G devices and current Cong, 〇 / 3. 〇 coexistence - The compatibility _ which occurs when the connection is controlled, and the stability of the 201117015 can also be improved. The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings. Read more from the 1st to the 1st of FIG. 1 as a US according to an embodiment of the present invention. Functional block diagram of the B host control device 1. Stereo flute 1 θ ^ _ 1 is not ' USB host control device 1 includes a chip set 10, a first USR 4 also k > coin host controller 12, a The second USB host controller 14 and the USB connection itch 16. The first Cong host controller 12 is built in the chipset 10 and the first USB host (four) $12 conforms to the first-brain specification. The second delete host control ϋ Μ Connected to the group ω, and the second Cong host controller 14 conforms to the second Cong specification, wherein the second café specification is different from the first job specification.
