Thanks, Brian
The problem is still there. I follow your instructions, and here is
the ouput:
r...@vietkhoa-laptop:/home/vietkhoa/microdia# insmod ./sn9c20x.ko
log_level=15
insmod: error inserting './sn9c20x.ko': -1 File exists
r...@vietkhoa-laptop:/home/vietkhoa/microdia#
r...@vietkhoa-laptop:/home/vietkhoa/microdia# cheese
r...@vietkhoa-laptop:/home/vietkhoa/microdia# LD_PRELOAD=/usr/lib/
libv4l/v4l2convert.so cheese
r...@vietkhoa-laptop:/home/vietkhoa/microdia#
dmesg produces an output which does not fit here, so I just copy the
part that I think is involved
