Xubuntu 7.10 on a Thinkpad T40.  Trying to connect a Canon Powershot A40 
camera.

I'm plugging in the camera, and it's not mounting automatically.  I'm 
not sure what steps to take to get it working.  I'm not familiar with 
all the steps to get from a USB device to a filesystem mount.

'lsusb' makes it appear that the system knows the camera is there.  I 
see device files in /dev which seem to correspond to the camera.  Same 
information shows up in dmesg.  I'm used to seeing a device as something 
like /dev/sda, and I can mount that.  I'm not sure how to do that with 
the multiple USB /dev files I'm seeing.  (There are 4 files in /dev 
which appear related to the camera, /dev/usbdev2.10*, see 'ls' output 
below.)

The camera powered off a few times while I was poking about, and dmesg 
shows it was re-detected every time I powered it back on.

My iPod mounts automatically when plugged in, with either the Apple or 
Rockbox firmware.  Is there some other module, driver, or daemon I need 
to install to get the same behavior from my camera?

thanks,
alex
