Hello to all,

I have stm32-h107 board, i use eclipse and yagarto toolchain (my OS is windows7).

I want to use the feature usb on the go to establish communication with my laptop.

i downloaded the driver for virtual com port and installed it in my laptop. Afterwards, i compiled the example ''Virtual_COM_Port'' ( taken from ''STM32_USB-FS-Device_Lib_V3.3.0''), and compiling gave no errors. The problem rises as i start the debugging : code 43 pops up, that is ''Windows has stopped this device because it has reported problems''. I check Device Manager and there is an ''Unknown Device'' under Universal Serial Bus Controllers with an exclamation mark. I load to this device the inf file that i have already installed, but nothing changes.

Any ideas are welcome!

Best regards,

Dion
