Tested on linux domU (ubuntu 12.04 64 bit) with usb redirection:
- with usb1 and usb2 working and no problem found.
- with usb3 linux sees the usb3 controller but usbredirection not 
working (tested with qemu 1.3 of xen-unstable)

Tested on windows 7 pro 64 bit domU with usb redirection:
- with usb1 not working, windows sees the usb devices (flash mass 
storage) with error (unable to start device, code 10).
- with usb2 working and no problem found.
- with usb3 not working, windows sees the usb controller but 
usbredirection is not working (tested with qemu 1.3 of xen-unstable)
Qemu log on usb3 test:
xhci_cap_read: reg 2 unimplemented
xhci: unimplemented command 52
xhci: ERDP out of bounds: 7e7d5000
xhci: ER[7] at 0 len 0
xhci: asserted controller error
xhci: ERDP out of bounds: 7eace000
xhci: ER[6] at 0 len 0
xhci: asserted controller error
...
xhci: slot 1 has no device
xhci: error firing data transfer


For usb1 and usb3 I used the qemu parameters posted by Paolo Bonzini 
last week.
Someone can help me to fix/improve that please?
Thanks for any reply.
