Here's some tips (don't know if they'll help)

1. lspci -v
- Tells you if the hardware has been properly detected.  Looks like yours has been.

2. lsmod
- Tells you if the driver module got properly loaded.  The driver parts of mine looks like this.
Don't get upset, I'm using one of the CKennedy drivers, which does a little bit more and looks a bit
different.  You should see entries like ivtv, msp3400, saa7115, i2c-algo-bit, i2c-core.  If you do,
then the driver is probably loaded OK.

ivtv-fb                25648   0  (autoclean)
tveeprom                7456   0  (autoclean) (unused)
ivtv                  788576   0  (autoclean) [ivtv-fb]
msp3400                19692   1  (autoclean)
saa7115                 7644   0  (autoclean) (unused)
saa7127                 7804   0  (autoclean) (unused)
tuner                  10208   1  (autoclean)
i2c-algo-bit            7144   1  (autoclean) [ivtv]
i2c-core               12676   0  (autoclean) [tveeprom msp3400 saa7115 saa7127
tuner i2c-algo-bit]
videodev

3. Do:
dmesg | less
(q to quit)

, and look for error messages.  If the hardware detection failed, you'll probably see error messages
in the listing (but you won't because it looks correct)

4. If you get an error that reports 'no such device', in my experience it meant the driver isn't
loaded, or you don't have permissions to the /dev/video* devices.  I've seen some instructions that
suggest doing:

chmod 666 /dev/video*
- sets the permissions properly (not sure about that)

or,

chmod 777 /dev/video*
- sets the permissions to anybody, anywhere, anytime.  A serious security hole and probably not a
good idea, but it will eliminate any permission issues with /dev/video.


Hope this helps, good luck,
Don
