I am affected by this bug. I have a Canon EOS 400D. Tormod Volden's fix works for me, but not always. It seems I can connect to the camera and import photos (using F-Spot) initially, but if I try to do a second import I get the error. A workaround for this is to turn the camera off and on again, effectively resetting the connection.
Let me know if I can provide any info. -- Workaround for USB digital camera photo download problems https://launchpad.net/bugs/6602 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
