Looking at the video4linux CVS HEAD, it doesn't seem supported yet.
If you know some C programming, the file I look at is viewable here: http://www.linuxtv.org/cgi-bin/viewcvs.cgi/video4linux/cx88-cards.c?rev=HEAD&root=v4l&only_with_tag=HEAD&view=auto
The two variables I look at are:
- cx88_board cx88_boards
The AVerTV 150 card of the other person had a subsystem value of 1461:c10b, which isn't listed in cx88_subids.
We support whatever the Video4Linux project supports. Their mailinglist is hosted by Red Hat: https://www.redhat.com/mailman/listinfo/video4linux-list
. You can try to talk to the developers there about your card. They may ask you some more specific info, or, if they already know about it, tell you so.
