I installed drivers from asus website, and i think i have all. When i compared usb cable pins and motherboard pins there seems to be one less in motherboard. Not sure how its meant to be.
That is normal there will be 1 pin missing on the motherboard in 1 corner.
What devices have you tried plugging into the USB ports? Do you have a couple flash drives, both 2.0 and 3.0 to see if it reads any of them?
Well i have tried usb stick 2.0 and 3.0 and it does not read them, only that window connection sound and notification about usb doesn't recognize device.
