[mythtv-users] multiple HVR-950Q usb tuners

A friend of mine has two of the HVR-950Q tuners and cannot get both of 
them to work at the same time.  I suspect this may be a driver problem 
and not a mythtv problem because even azap will not tune on the second 
adapter.

The main symptom is the first tuner works fine, but the second tuner 
does not appear to work at all (azap, scan, mythbackend).

We've tried the "options xc5000 no_poweroff=1" suggestion and it does 
not appear to help this issue.
