This detection and auto-mounting of plugged in media is generally part of 
the desktop you run. I am using TDE, up to date version r14, and when I 
plug in my junk cell phone when its turned off, it goes into charge mode 
until it topped off, then a TDE Daemon finds it and mounts 
to /media/somenumber automaticly, giving it access perms only from the 
owner of the desktop.  Only 50 megs of ram so obviously its a fat-16 
file system.

I doubt, if you are not running a desktop, that such an automount 
facility is available or running on your system.

One way to do it manually is to run 'blkid' from a shell, which will 
output a unique identifier for each device it can find.  My phone for 
instance, shows up in the list blkid outputs as

/dev/sdd: SEC_TYPE="msdos" UUID="2A21-0001" TYPE="vfat"

you could then construct a mount command, see mounts man page, useing 
either the /dev/sdd (discouraged as it is not unique and yours may be a 
different sd#) or the UUID=number, which will be different from mine, 
using the vfat filesystem, mounted to /media/2A21-0001 in my case.  The 
UUID method is much the preferred method, and that is the name its 
mounted at too.

I am pretty sure such an auto function could be hacked up in a bash 
script, I've done them critters for 2 or 3 things here, but not this 
since my gui of choice handles it.

But I think you can see from the above what needs to be done by hand if 
your desktop isn't in use.

IHTH.
