arduino leonardo not recognized by usb cable in wi

Question

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?

Reinstall/update arduino leonardo drivers and see if the problem is solved.
