HVR950Q ATSC / QAM is supported in the master development repository, and it is in upstream 2.6.26 and later.

You need the xc5000 firmware.

[   17.247610] usb 5-2: new high speed USB device using ehci_hcd and 
address 2
[   17.380387] usb 5-2: unable to read config index 0 descriptor/all
[   17.380434] usb 5-2: can't read configurations, error -71

^^ This is not a firmware problem, but looks fishy.  If using the latest drivers from linuxtv.org doesnt work for you, then try another USB port, or confirm that it also works in windows.

Good Luck,
