I've had some trouble trying to mount a Sony DSC-P1 via USB.
In 1.5.1, it just shows up as a generic device.  In -current,
it has been added to the list of quirks for the USB mass storage
devices, so it shows up there.  Alas, I can't seem to mount it,
or even dd from the raw device:

Has anybody had success with mounting this camera via USB?  Or any of
the other DSC series cameras?  I'd love to hear that I'm just an idiot,
and I misconfigured something...

Thanks,
