Yes, I checked with 2.6.6, it still works. > Second, what happens when you apply this patch to 2.6.7: > > http://marc.theaimsgroup.com/?l=linux-usb-devel&m=108593392122076&q=raw > > (Although it's possible that patch will help, it doesn't affect anything > that has changed from 2.6.6 to 2.6.7.) I applied the patch but it didn't help, the symptoms are the same. Removing the LIRC modules (which tainted the kernel) and the hotplug script "my_usb" (used to mount the camera) also didn't help. I rebooted a couple of times, and once cupsd got stuck (it didn't start). I'm loading the usblp module, although the printer is powered-off. I'll try again with 2.6.7-rc1. What else could I try? Remove all USB hardware and see if the camera alone would work? Anything else? Regards...
