Don't think so :) Everybody wants a working camera :-))

Great !!!!! I used the patch and it works OK. I can't test the multiple
camera option :) The rest seems to work great. One question, all drivers
so far have put a huge load on the machine when starting the ./main
client program. Even my dual celeron with a lot of mem becomes slow.
Does the same happen for you?

to tell there is a new image ready (???) and the current driver is just
polling al the time??

Scott, if you want I could put up your patch, until Jarl is back and
reading, with a small readme file and the already patched driver for
I-can't-patch-myself users ;-) I also have the wcIIcam file online and
that has been doenloaded over a hundred times, and I have never seen
more than 15 ppl here :-)

Thanx again,

Bas (who is hoping that in some time he can run his webcam from Linux
instead of booting to NT ;)
