ls /proc/bus/usb lists as empty with the scanner on. /var/log/messages says: Mar 15 13:14:40 musicbox kernel: usb 3-1: new full speed USB device using ohci_hcd and address 2 lsusb -v doesnt seem to work, giving me nothing but: Unknown line at line 4969 Where the number of the line changes, going up to 5004 dmesg | grep usb tells me (among other things): usbcore: registered new driver usbfs usbcore: registered new driver hub usbcore: registered new driver hiddev usbcore: registered new driver usbhid drivers/usb/input/hid-core.c: v2.0:USB HID core driver But on boot I remeber seeing usbdevfs not supported by kernel or something. Could this be becasue the module isint loaded yet?

See above for lsusb -v. sane-find-scanner doesnt find the scanner. Thanks for the help so far! What can I try next? Could it be a hotplug misconfiguration of some sort? -thewade
