I have installed this device:
AVerMedia AVerTVHD Duet - PCTV Tuner Model #A188
it has, up 'till now, never had a working driver for Linux.
Netsearching the device today, I see:
where, someone, has made the driver for this device work. Can anyone confirm this and if the driver will work, please explain (show me a link to) how to install this in my stock, kernel unmodded Precise Pangolin ver. 12.04 LTS?
