    Default USB Oddities - Z87 Extreme4

    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.

    hi; toggle the option of "usb legacy" in bios (if exists) and check.
