I have got the same problem (error message) as above, exactly the same output
from dmesg.
The above lines are generated after pluging in the Dazzle DVC-80 (Digital Video
Creator) - an USB device for capturing analog video from Composite or S-video
input.
This device is at least partially recognized by USBvision, b ut so far I
have not been able to record a single frame from it under Linux. I tried
mplayer, mencoder, xawtv , ... - nothing worked with DVC-80 so far.
I have recently installed Ubuntu 8.10, kernel 2.6.27-7, then upgraded to
-2.6.27-9.
I would be grateful for any hints (or patches, error correction) on how to make
DVC-80 working.
I am attacing two screenshots from the Device Manager with info on
DVC-80 (which is also for ssome reason referred to in some places as
DVC-800, but it is actually the same device).
Below is also the output from v4l2-conf --all, and lsusb. Do you need
any other information?
> v4l2-ctl --all
