[arch-general] digital camera not showing as mass storage device

I can get my digital camera to work with libgphoto stuff like shotwell, but for months now it simply won't show up as a mass storage device. Am I missing a kernel module or something? I loaded usb-storage. I downloaded the Ubuntu 10.10 beta live CD, plugged the camera in, and it popped up fine as a hard disk /dev/sdX... In the logs I see a load-modules.sh error. Please advise.
