hi there I recently purchased a new motherboard for my new build a z590-e and i am confused on why my usb 3. However, after reading your posted information it seems that one or more USB 3. If the USB ports not working on your MacBook Pro or iMac is a recent issue, and there doesn’t seem to be any problem with USB devices, it could be that an app is conflicting with USB functionality.That one isn't connects to the other USB ports so why would that one be out also? Sometimes the motherboard needs to be “rebooted” because things can go wrong, i. New motherboard usb ports not working One port is slightly damaged but not enough to physically prevent inserting a USB however they don't seem to provide any power or anything to the things I plug in.
