After everything worked fine when booting from CD (modem, usb-stick, usb-camera) I installed the same Knoppix-version 3.3 on hd. But now I can't access my modem by kppp thru ttyS0 (error message "Can not open Modem Device") and no access to the usb-devices (error mesasage by USBView: "Can not open the file /proc/bus/usb/devices"). What shall I do to get these working and where can I find what the differences are between CDRom boot & booting from hd?

thx in advance,
kabs
