Hi All,

My system configuration is as folows:
- clean Ubuntu8.10 (live CD) - kernel 2.6.27
- my USB sonixj camera connected - it is 0c45:612a Microdia PC Camera 
(SN9C110)
- dmesg shows no errors or suspicious messages

Problem: I cannot get any application to work with my camera. Even svv 
mentioned in http://moinejf.free.fr/gspca_README.txt does not work. Logs 
for svv and streamer are below. Attached is also a raw file generated 
with svv (just 2kB in size). The logs show JPEG conversion errors. 
Anyone has a similar problem? Any helpful ideas on what to do?

I appreciate your help.
Thanks,
JJ

svv returns the following errors (or similar - it often asks for a 
different number of bits, sometimes it complains about unknown huffman 
code during JPEG decompression):

streamer (another application that I tried) returns a similar conversion 
error:
