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.
