[pvrusb2] driver status / update

[fivenote]

Everything is working!

My final problem was with mythtv-setup. When I ran it from the desktop
shortcut it created it runs gksudo and I enter my password to have it
run as root. But for some reason it won't open the analog side of the
card for me to configure it for mythtv.

If I open a terminal and 'sudo su' then 'mythtv-setup', it can open
and configure the card. Go figure.

I noticed something similar when I was using the sysfs interface to
test pvrusb2. If I 'sudo echo television > cur_val' I get permission
denied. If I 'sudo su' first, I can then write values.

Thanks to Mike and Hans and the other v4l-dvb developers for working
through this. You are a very responsive and helpful developer group.

I'm diggin my new pvr.
