The front USB ports are working selectively. In windows explorer (and bios) a USB 3.0 device won't be detected, tried multiple devices including a sata to usb converter. However, when I plug in a USB 2.0 flash disk, it is detected fine. The ports in the back work fine, no issues. The port is enabled in the bios, xhci is enable. I also tried disabling it but it doesn't help. BIOS version 2.57 installed. Is this a hardware issue or do I need to reinstall the BIOS? I am completely confused. Thanks.

Googling I have read that this problem can occur if the "20" pin cable is damaged, partially connected (loose) or pins bent
here is one example
https://superuser.com/questions/1347158/what-can-cause-a-usb-3-0-port-to-revert-back-to-usb-2-0
another "fix" was made by allowing some slack in the cable so that it was no longer bent or twisted by a cable tie.
The 20 (19) pin connector to front panel has both USB2 and USB3 wiring. and it seems that the USB2 is used when usb3 has a problem
Look for bent pin or try another cable. Post back here if you fix the problem.
Hope this helps
