Problems mounting a cell phone

[MR ZenWiz]

I have a Casio C811 G-zone cell phone that I'd like to be able to
acess from my Xubuntu 14.04.1 system.

When I plug it in to the USB port, it shows up in lsusb as an NEC
device, but the file system never mounts and I can't seem to access it
as a /dev device.

The phone has version 4.12 of Android, if that's any help.

Any suggestions welcome.

Thanks.
MR
