I wonder if the problem is actually internal to the HD-PVR, or is some 
sort of problem with the USB subsystem or the drivers.

I have an HD-PVR that I use manually outside of Myth. When it stops 
working I unplug the USB cable, wait a minute then re-insert it. This 
has always fixed the problem, with no power cycling of the HD-PVR needed.

Of course the HD-PVR may reset itself when it's plugged in to a USB 
port, so I'm not sure how to determine at which end of the USB cable the 
problem lives.

So I'd guess that power cycling the HD-PVR would also fix my problem, but 
it would be nice to know where the problem actually is.

The main symptom (other than not working) is when I start a recording 
(with cat) the red LED does not light up, which is how I know I am in 
the "failed" condition without having to check for a recorded file.
