Describe the bug
Linking fails with STM32Duino platform >2.7.1, due to changes in the USB CDC code structure when STM32duino updated from 2.7.1 to 2.8.0
To Reproduce
Steps to reproduce the behavior:
- Download Sloeber Product 4.4.3
- Add Platform from STM32Duino version >2.7.1
- Try any code with USB Serial (USB support to CDC gerenic Serial Supersede USART)
- Add the srcWrapper library and try to compile (Errors during linking will occur)
Snippets of the errors:

STMicroelectronics/hardware/stm32/2.8.0/cores/arduino/WSerial.cpp:66:(.text._Z14serialEventRunv+0x18): undefined reference to USBSerial::available()' - (workaround attempt) Add USBDevice library, compile and run (USB Serial will not work)
platform:
Arduino Core STM32

Expected behavior
The linking should work (i.e. the library should be added automatically) and no workaround (manually adding USBDevice.h) should be employed
Data to back up your claim
Even if the workaround of manually adding the USBDevice.h causes the code to compile, the Serial does not work, as explained in a similar issue that happened on Platformio
