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".

I have an external hard drive set up on the Sheevaplug, mounted as /media/D.  How do I set that up so that a subversion download goes to that drive instead of to the internal flash?
