I've currently got a Canon G5 camera set up and working happily under
Linux (Slackware 10.1) with kernel 2.6.11.7 so that I can access it via
GPhoto2.

However, I want to mount the camera's compact flash card directly as a
filesystem so that I can recover some accidentally-deleted data (oops).

I did this once last year with a 2.4 kernel, but can't figure out what
device the system needs me to use for it to work with a 2.6 kernel.

Hotplug's reporting the camera device as /proc/bus/usb/003/003 - but mount
doesn't think this is a valid block device.

Nor is it /dev/sda1 - that's the first partition on my SCSI drive of
course (I've got SCSI devices in the machine).

Nor is it /dev/sdb1, sdc1 etc.

Any ideas? Maybe there's something I need to disable first? Wish I'd
written down how I did it last year now! :-)

FWIW, lsmod output is:

relevant line in /var/log/messages:

Jun 29 12:52:23 pukeko kernel: usb 3-1: new full speed USB device using
uhci_hcd and address 3

/etc/hotplug/usb/usbcam is (echo line added by me just so I can see what
it's using):

#!/bin/bash

if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
  echo ${DEVICE} > /tmp/camdev
  chmod a+rw "${DEVICE}"
fi

catting any stuff under /proc/scsi doesn't show up anything
camera-related.

Any ideas?

cheers
