sn9c102 webcam driver in kernel 2.6.11.6
Dear List,
I've previously posted this question in linuxquestions.org, but having
gotten no replies, I'm posting here; apologies for those who've already
read it.
I have a webcam (ID 0c45:6029 Microdia Triplex i-mini PC Camera) which was
working fine under kernel 2.6.10, in my hard disk installation of MEPIS
3.3 (a Debian based distro). I had been using gnomemeeting with this
webcam. However, after upgrading (from the MEPIS apt pool) to the kernel
2.6.11.6 image, the webcam stopped working in gnomemeeting, despite making
sure that gnomemeeting was correctly configured. The new kernel does load
the appropriate driver, namely, sn9c102 module at startup (I presume
hotplug takes care of it).
I'd appreciate some feedback to try and pin down the problem. I'm
including the output of lsmod below, first with the previous kernel 2.6.10
where the webcam was working fine:

`-----
As you can see, the only major differences are that modules udf, sg, drm,
and rsrc_nonstatic are loaded in 2.6.11.6, but not in 2.6.10.
Does anybody have a hint as to where/what to look for?
