I've just had the same problem with my Nikon P4 in PTP mode, and the same fix worked out.
It looks like this bug is pretty common, so I advice changing the bug title to something like: "My USB camera doesn't work, 'Could not claim the IO device'", and getting everyone using Edgy to know about it. Anyway, thanks for the hint. Maybe adding more device definitions to this udev rules per default would be a good idea. Merging Dapper and Edgy files maybe, as it worked just fine back in Dapper days. Thanks. -- "Could not claim the IO device": Canon IXUS 65, Edgy https://launchpad.net/bugs/64146 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
