This board has been working great for over a year and then yesterday the USB ports went completely funky. If I plug in a USB1 device (keyboard, bluetooth dongle) then it works great.... if I plug in a USB2 or USB3 device, it doesn't show up. Not in the BIOS or boot options, not in Windows, not in a Live Linx distro.

Any ideas?

I've cleared CMOS values, upgraded the bios, etc. These thumbdrives and USB devices work on 2 other PCs.

What OS are you using?

If Windows, what do you see if anything in Device Manager about your USB ports? If you connect a USB flash drive, does anything change in Device Manager?

Your board only uses Intel USB ports. Is it any USB port that won't work with the USB flash drives, or only the IO panel, or front panel?

Any kind of changes in the PC before you changed the BIOS version? Any recent Windows updates?

Some USB flash drives have LEDs that flash when the drive is active, or when first connected. Do you see that happening when connected to the PC?

Windows 8.1 when the problem first showed up. Upgraded to Windows 10 to see if it would solve the problem.

This is with USB3 disabled in the BIOS. If I enable USB3, I do get another USB3 device that appears.

Sometimes device manager will display a "Unknown USB Device (Port Reset Failed)" when something is plugged in, but not always -- and never when I have the USB3 enabled.

I have tried front panel, IO Panel (both the USB2 and the USB3 ports.) It doesn't seem to matter.

No updates or changes until the problem occurred.

When I plug in a flash drive, it will blink to indicate it has powered up, but it won't blink after that.
