Looks like you may have to pass a 'tuner=#' option too, isn't cheap noname hardware just so much fun? I used a script to do it quicker.

Here is a slightly modified one that should work with your drivers.

Code:

#/bin/sh
MAXTUNER=69
for i in $(seq 0 $MAXTUNER);
do
           rmmod tuner em28xx
                       modprobe em28xx card=4 tuner=$i
                       echo "Actual tuner is:" $i
                       sleep 1 # this is to make sure /dev/video is registered when tvtime starts
                       tvtime
done

Posting the dmesg output from the card would really help.

Have you tried all card= and tuner= options? It may take a while, but once you know you will never have to do it again.

tommytomthms5 · 01-04-2008, 07:16 PM

i know the card option is 35 but i ran that script to go through all 69 tuner options for nothing.....

elliott678 · 01-04-2008, 08:03 PM

How are you sure your card option is 35? My card works with more than one option, but I get stuff like inputs being switched, only s-video input...etc...etc....

tommytomthms5 · 01-04-2008, 10:51 PM

[ 17.400000] em28xx #0: Found Supercomp USB 2.0 TV

35 -> Supercomp USB 2.0 TV (EM2821) [eb1a:2821]

thats how sure

elliott678 · 01-04-2008, 11:51 PM

You get that without setting a 'card=' option? Then, if you haven't already, remove the 'card=' part of that script and run it that way.

Something simple is wrong, if the driver knows what the card is on its own then you can't be too far off.
