I would have been even faster if the sunny weather hadn't convinced me to go biking today :-) > Here is the new dmesg: > > http://tux-style.de/tmp/dmesg_patch_applied.txt > > Now in webcam mode the lucview tool found a /dev/video0 device, but > exits just after showing a window for a second. > > Here is the output: > > luvcview version 0.2.0 > Video driver: x11 > A window manager is available > video /dev/video0 > Unable to start capture: 38. > Error grabbing > Clean Up done Quit > > Here is the strace output: > > http://tux-style.de/tmp/lucview.strace Are you using a USB 1.1 device behind a hub ? Error 38 is ENOSYS, and the only occurrence of that error in the USB stack code seems to be related to split isochronous transfers. Can you connect the camera directly to the computer if you're using a hub, or turn on CONFIG_USB_EHCI_SPLIT_ISO ("Full speed ISO transactions") in your kernel ? There is no point in testing dv mode, only webcam mode will work for now. We will try dv mode after being done with webcam mode.
