Sony USB camera mounts read-only

[Larry Hunter <Larry.Hunter@uchsc.edu>]

Folks,

I recently purchased a Sony DSC N-1 camera.  Plug it into to two
different debian boxes (both running fairly current unstable
distributions on kernel 2.6.16-2) and it nicely automounts as a USB
drive. 

However, it mounts read only, which is problematic.  I'm just looking at
the internal memory of the camera, not an additional memorystick, so
there's no physical switch to check.

Here's the relevant dmesg log:

        usb 3-5: new high speed USB device using ehci_hcd and address 3

I tried hdparm -r0 /dev/sdc  but that didn't do anything.  Is there a
configuration file or gconf entry somewhere I should look at?  Any other
ideas?

Thanks,
