Hi,

It seems that the USB ports from your motherboard aren't being recognized. I would try installing the latest version of the chipset drivers.

First you need to know what chipset brand your motherboard uses (Intel, VIA, SiS, etc).

Then go to the chipset manufacturer website and download the latest drivers:

I hope it helps.
