Are you using USB 3 or 2? I've seen similar error reports elsewhere (non dt) where the only solution was to switch to a USB 2 port (if one was available).

I have turned off all automatic mounting of external devices and the following displays in the terminal: david@david-T400:~$ darktable -d camctl [camera_control] creating new context 23fa980 [camera_control] loaded 1451 camera drivers. [camera_control] loaded 41 port drivers. [camera_control] 1 cameras connected [camera_control] gphoto2 error: PTP I/O error [camera_control] failed to initialize camera Canon EOS 50D on port usb:003,003 [camera_control] failed to initialize device Canon EOS 50D on port usb:003,003, probably causes are: locked by another application, no access to udev etc. [camera_control] registering listener 44b4340 Ideas to solve this would be appreciated. This really is a nuisance. Darktable crashes if I try to remove the camera even with the camera turned off.
