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,
