[Bug 280657] Re: Intrepid kernel 2.6.27-6 no supported image sensor dected for SN9C105 (045e, 00f7)

[Jonathan]

I just wanted to say that I may have made a little bit of progress with this.  I was playing around with loading/unloading different kernel modules to see if it affected anything.  It appears to be kind of flaky, but I'm able to get it to detect my sensor sometimes.  For this, I did:
sudo modprobe gspca_sonixj
sudo rmmod gspca_sonixj

This leaves gspca_main on, but not gspca_sonixj.  Unfortunately, I don't think it was working with just loading gspca_main.
Here's a little more info from dmesg:

jonathan at jonathan-ubuntu:~$ lsmod | grep gspca
gspca_main             33536  0 
compat_ioctl32         18304  2 gspca_main,sn9c102
videodev               46720  3 gspca_main,sn9c102,compat_ioctl32
usbcore               175888  6 gspca_main,sn9c102,btusb,uhci_hcd,ehci_hcd

Previously, that command didn't bring up anything because gspca wasn't
loading at all.

Unfortunately even though the sensor is detected, I can't get any apps
to recognize it.  Cheese and Ekiga both just hang like they're trying to
use it, but can't.  I also tried using the LD_PRELOAD stuff, but that
didn't seem to help.  So I'm thinking this is just a waste of time, but
I thought I'd offer it up just in case anyone can make more sense of it
than I can.

Also, I tried loading a few other modules, like gspca_sonixb, without
much luck.  If anyone has any other suggestions for things to try, I'll
do it!
