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.

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.]]> Wed, 16 Sep 2015 10:16:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=835&PID=3755&title=usb-oddities-z87-extreme4#3755
