It did not help, but it *does* seem to be a permissions problem... doing "chmod a+rwx /dev/usb*" now gives me

network socket
network beh
network bluetooth
direct usb://Canon/MP600
network http
network ipp
network lpd
network smb

Thanks!

Any idea what the problem might be? Might some process run as another user than cupsys?

Will investigate...
