Arduino not recognized on windows PC



I am trying to connect the mangoh’s arduino via serial port in order to upload sketch but l got a message error like “usb device not recognized” I have tryied with another PC but same message. Does anyone already meet this kind of issue? Any command to reset everything related to the arduino ?

I have already tested it before and it worked well one time but not anymore.

Thanks in advance


It’s been a while since I’ve used Arduino, but if you have an AVR programmer you could reflash the Arduino bootloader through the ICSP header
