With Fedora 17, when you install a flash drive, it no longer shows up as an entry in /media.
Fedora 17 qualifies the mounted device as /run/media/user/device, because the device should be mounted as private.
If you want it universal, I guess the way to do it is to change the directory permissions.
Since I am writing this in the public library, using their computer, and going from memory, the sequence to access your device from the command line could be /run/user/media/device but definitely not /media/device
