The uvc video drivers for web cams are reported to be included in Ubuntu, but appear not to be available on the Sheevaplug. I have not been able to find anything in the repositories which seems appropriate. How does one load the modules which will recognize web cams? lsusb shows:
Bus 001 Device 003: ID 046d:09c1 Logitech, Inc. QuickCam Deluxe for Notebooks
"ls /dev/video*" shows nothing, as does "dmesg | grep video".
