Easy enough to fix with udev...  Find some unique key for the device with
udevinfo (USB keys have product names and serial numbers, I would expect
cameras to have the same), create a udev rule assigning a synonym such as
"usbkey" or "canonXY", and change your fstab to mount /dev/usbkey
and /dev/canonXY.
