That's what I meant above. Shut down your PC completely. If your USB
ports are still powered after a shutdown, look in your BIOS to power
them down.


Have a look in your syslog whether the stick is found in a "cold state"
or a "warm state" when booting.

Mine works absolutely fine alongside a Hauppauge Nova-T 500, which give
me 4 physical tuners in total. But my backend shuts down when not in use
and wakes up when a recording is about to start. So I never reboot my
backend knowing that the Hauppauge card has problems with it. Maybe the
USB tuner has problems with a reboot too, I'll never know... ;-)
