About my setup:

  • Windows 8 64-bit.
  • X79-UD3 Motherboard.
  • Latest Windows 8 USB 3.0 Drivers from motherboard manufacturer website.

All right so device manager detects my USB 3.0 ports, so all is well there.

However when I plug in my external USB 3.0 hard drive, windows doesn't even make a beep; the hard drive is not picked up by device manager at all.

The SAME thing happens with Ubuntu 12.10 BUT adding PCI=nomsi (as a workaround) to the Grub command line of the Ubuntu boot option makes Ubuntu 12.10 detect my external hard drive.

I also have a few other doubts, if you guys would be kind enough to answer them that include:

  • Should XHCI hand-off in the UEFI bios be enabled or disabled for Windows 8?
  • The difference between XHCI hand-off and EHCI hand-off and what are it's effects on USB 3.0 functionality?
  • And last but not least how can I get Windows 8 to recognize my external hard drive when Ubuntu 12.10 (after the Grub workaround) works fine?
