Arduino not recognized on windows PC

Hello,

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

You may refresh it or restart the system. What can say more than this my windows taskbar auto-hiding option is not working after enabling it. The taskbar won’t hide and other applications also stop working. I need to fix this.
