USB3 and HD-PVR

Turns out USB3 is still unstable in Ubuntu 11.04. When the HD-PVR is connected to USB3 will fail with the following in dmesg:

[ 1603.561520] xhci_hcd 0000:04:00.0: ERROR no room on ep ring
[ 1603.561524] hdpvr 9-4:1.0: usb_submit_urb in hdpvr_submit_buffers returned -12
[ 1603.561527] hdpvr 9-4:1.0: couldn't submit buffers

Just switch back to USB2 and the issue should go away.
