Digital camera not detected in FC5

I had a problem with gtkam only connecting to the camera if I ran it as root, but recently (in the past week or two) it's even stopped working as root.

I think it's a fairly low level problem (UDEV?) because the camera's not even being recognised by lsusb:
(starting with the camera turned off)

I can see that some of the UDEV files were updated recently:

I think it's 50-udev.rules that I need to look into, but I don't know enough anything about UDEV.

(Update: I discovered the udevmonitor command - output added below)
# udevmonitor
udevmonitor prints the received event from the kernel [UEVENT]
and the event which udev sends out after rule processing [UDEV]

Any ideas?
