[pvrusb2] mythtv and wintv-hvr-1950 - analog/digital scanning

Thanks. Tried chmod 777 on /dev/video0 but no dice.

Doing as Mike suggested and making sure I rebooted w/o mythbackend
starting, I can't even cat /dev/video0. I get Input/ouput error. I may
have mentioned that before.

I went back to testing with mythtv for a minute and noticed this...
When myth opens dtv, enum_val lists only dtv as expected - narrowing.
When I tell myth to switch to analog television, I see enum_val lists
television,composite,svideo for a few seconds. I figure it is opening
the analog side of the card, narrowing out dtv, but then failing.
After a few seconds, enum_val lists all four entires, showing both
sides of the card are closed. When running mythbackend and scanning
for analog channels, the same thing shows under enum_val - the analog
card is open and dtv is narrowed out of the list while it scans and
finds nothing.

I'm also seeing this series of entries in /var/log/syslog when myth
tries to read the analog card...

FWIW... here's the series of entries in /var/log/messages when I
connect the HVR-1950...
