About my setup:
- Windows 8 64-bit.
- X79-UD3 Motherboard.
- Latest Windows 8 USB 3.0 Drivers from motherboard manufacturer website.
- Latest BIOS revision. (F12p)
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:
XHCI hand-offin the UEFI bios be enabled or disabled for Windows 8?
- The difference between
EHCI hand-offand 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?
