gphoto2 and Canon IXUS 500: permissions problem?

My (very nice ) birthday present this year is a Canon IXUS 500 - one stylish digital camera! - and I'd like to get it working with gphoto2 (v. 2.1.0) and gtkam on my Red Hat 9 system.

The good news first: at the terminal,
gphoto2 --auto-detect
tells me there's a "USB PTP Class Camera" on the system, so at least the camera is recognised.

Unfortunately, gtkam gives me a "Could not initialise camera" error, and
gphoto2 --summary
expands on this, saying "Could not claim the USB device". The gphoto2 FAQ suggests this message means either another kernel module is using the device, or the permissions on the device are not set properly.

To be honest, I'm not that advanced a Linux user yet If it's a kernel module problem (and I have a gut feeling it isn't), how could I find out?

On the other hand, if it's a permissions problem: I've tried the steps to set up hotplug in the gphoto2 manual, but it seems to have had no effect.

Has anyone else managed to get an IXUS 500 and gphoto2/gtkam working together?

Many thanks,

P.S. Two lines from /var/log/messages which may help:
... kernel: usb.c: USB device 8 (vend/prod 0x4a9/0x30b4) is not claimed by any active driver.
... /etc/hotplug/usb.agent: ... no modules for USB product 4a9/30b4/1
