If the latest BIOS doesn't fix your problem then try updating your AMD Chipset drivers and see if that fixes it.
Otherwise disconnect all USB hardware to your PC except your Mouse and Keyboard and see if the error goes away in Device Manager.
If it does, start connecting one USB to your computer until the error appears again. Then you will know, at least, which USB hardware is causing the problem.
Otherwise unless someone else has other suggestions i am out of them.
