a) MTP didn't work out of the box with ViBE as a mountable filesystem b) I've always had issues in the past with MTP, so I just set to MSC which is more of an industry standard and is more mature on linux c) it works on Karmic d) a cursory search of launchpad reveals similar bugs for other devices which were considered worth fixing: https://bugs.launchpad.net/ubuntu/+source/libgphoto2/+bug/330383 https://bugs.launchpad.net/ubuntu/+source/hal/+bug/236422 https://bugs.launchpad.net/ubuntu/+bug/345916 I set the device to MSC so it should be detected as MSC. (And is, when the offending rule is removed). lsusb output showing the ViBE identifying as a Mass Storage class device.
