You have gone through the BIOS and verified the settings are correct? I assume yes. if not please go over the manual and verify the BIOS settings are not the issue.
a mechanical problem seems most likely. ie. bad insulation, corroded wire, bad connection
it could be the header on the motherboard, or the cable that attaches to the header. the problem is you only have one of each so testing which is bad will be difficult.
from the pictures I could find the USB 3.0 cable is the covered blue one on the case? correct me if wrong.
the motherboard has one header that will fit that cable? correct me if wrong. Going by pictures here.
Yes you're right there is only one of each which sucks but in windows it says:
USB Device (Device Descriptor Request Failed)
try this:
go to device manager
open the list of USB devices if not already opened.
on the first device right click on it and go to update driver.
then do the same thing for the second and third, down through the list until problem resolves.
if nothing try this
turn off the computer. unplug your phone from the port, remove the power cord from your PC for 30 seconds, plug in pc , reboot, when windows is loaded, plug in phone again.
if neither of things work let me know I'll keep looking
