[pvrusb2] Black screen, device stuck, need to power cycle to clear

[Bill Kristan]

New problem... my wintv-hvr-1950 now works only briefly, then stops. The
device node is still there, and I can play it (with mplayer or mythtv), but
it gives a black screen. The first time I saw this, dmesg gave a "device
stuck" error from pvrusb2. Removing and loading the module didn't fix it,
nor did rebooting the computer, but power cycling the capture device did. I
was able to play /dev/video0 with mplayer, but when I tried to record with
mythtv I got a black recording again. No error message was reported the
second time.

I'm using the firmware extracted from the driver CD.

What else... the dmesg output is here, but I don't see any errors:

Not sure what to try ... maybe go back to the firmware from isely.net? Seems
the version shipped with the device would be best, but it would be something
to try.

Thanks,
Bill
