问题
Actually the arduino leonardo working properly but from last 2 hrs when I connect it to my pc through usb cable it is telling something like usb is not recognized and even in device manager it is not showing.
When I press restart button in arduino it will detect as arduino leonardo bootloader(com 7) but after few seconds it dissappears.
What have I already tried to do:
- restart pc
- changed usb cable
but the same issue.
I checked usb by connecting other devices it works fine but the arduino is not recognized. I tried in other pcs also but the same problem continued.
What can I do?
回答1:
Reinstall/update arduino leonardo drivers and see if the problem is solved.
