Hi,

I'm an owner of z77 extreme4 motherboard. I have installed two operation system: win 7 64bit and debian.

The usb problems started with some failure of the ports.. I passed that problem with a new USB expansion card..

Unfortunately now during the boot all the usb ports doesn't works and I must use an old PS2 keyboard to choose the Windows OS in the GRUB bootloader list.. Infact after the booting time some USB ports works properly..

If I choose Debian I get theses errors:

usb device not acception address

usb device descriptor read/64

unable to enumerate USB device

I tryed to fix the issus with some solutions:

1. reinstall all the usb driver

2. update the boot firmware

3. reset bios - clear CMOS

but it didn't work

Have you got other solution to fix the problem? I think the problem is hardware.. I tryed to find a new motherboard but it's too old..

Thanks for your help!
