What does get returned by dmesg?

This means that this is probably not gspcav2 as it has been merged into the 
2.6.27 kernel, please use that version. See:
http://moinejf.free.fr/gspca_README.txt

Note that streamer is part of xawtv and xawtv has known bugs which are 
triggered in certain use cases when used together with gspca, you should really 
compile xawtv with this patch:
https://bugzilla.redhat.com/attachment.cgi?id=313380

What we *really* need is a new upstream for xawtv (as its still quite popular) 
even its just a place to collect all fixes currently scattered over many 
different distros. So any volunteers to organize this?

Regards,

Hans
