Question Problem with all the USB ports

[metallica1175]

All USB ports are receiving power, but none are recognizing any peripherals. This is both the motherboard and case USB ports.

I was installing a fan, and after I turned the PC on I noticed all the USB ports were not working. I checked to see if I knocked out anything on the motherboard, seems everything is plugged in. I reset the CMOS. I was able to find a PS/2 keyboard, and uninstalled and reinstalled USB drivers. I know the ports have power because they charge my phone. I don't know what else to do.

I would reinstall Windows if I could, but I can't because none of the USB ports work to put in a flash drive. The motherboard is an ASRock B450m Pro4 and it's only a few months old. Could the USB ports be shorted? If so, how could both the motherboard and case USB ports be shorted since they're separate? Any help? Thanks.

Since the motherboard is in warranty, contact ASRock support so they can send you a replacement if needed. You already checked over what you should have on your own.
