Question USB 2.0 ports won't work on my Gigabyte GA-970A-DS3P FX motherboard. USB 3.0 ports work great.


I have an issue with my USB 3.0 ports working great, but my USB 2.0 ports not working at all.

It's become really frustrating. Can you help me troubleshoot why the 2.0 ports won't work?

Here's some system information:
