Today I was working away when I tried to plug my headset into my Front USB and it would not work. From what I can tell there are 2 connectors each controlling 2 ports but only 1 port is not working. I assume it is the cable but I have no idea what it is.
try to find another wiring harness similar to the one you have or if not another front panel with front usb ports. i had a similar problem and couldnt find another wiring harness similar to the on i had but managed to get another front panel and problem solved
I had a problem where scan disk flash 8 gig drive stopped working on the front ports but worked in the rear ports it drove me crazy. Other flash drives worked in both ports( Front & Rear) What worked for me with a MSI mother board was to install a PNY usb flash in the front port find out where the port was in device manager ( showed up as mass storage device) uninstall the the device and then plugged in the problem flash drive and windows then saw and reinstalled the driver.
