Thanks for testing!

Ok, so a couple of things:
1) For the new xirlink cit driver to work you need the latest libv4l
from v4l-utils (use the just released 0.8.1 for example), but that
does not explain the io errors.

2) Make sure you the old usbvideo ibmcam driver is no used (remove the
.ko file from /lib/modules/...

3) Do
echo 63 > /sys/module/gspca_main/parameters/debug
(as root, note sudo does not work with redirects)

And then try some application again and after trying do
dmesg > dmesg.txt and attach dmesg.txt to your next reply.

4) What did you need to change exactly, can you share the changes
in question with me in the form of a patch ? (I'm waiting for
Douglas to sync the main hg v4l-dvb tree with the latest upstream /
mauro's tree and then I'll rebase my ibmcam tree.

5) Do
lsusb -v > lsusb.log and attach that to your next mail too.

Thanks & Regards,

Hans
