The following is a 'catch *everything*' approch.
There are "less-drastic" ways,  bud you don't provide enough
information to determine what short-cuts are possible.

*FIRST* _shut_down_ the machine.
Next, remove the USB device.
Now, turn on the machine and boot into FreeBSD.
Do an 'ls -l' of the /dev directory.  save the output to a file in your home
directory.
Plug in the USB device.
Did you get system log and/or console messages about a new USB device?
 (if not, you may be missing USB device suport from the kernel0
Again, do an 'ls -l' of the /dev directoy.  Save the output to a *differnt*
file in your home directory.
Look for device entries that are mentioned in _this_ list, that are *not* in
the list you got when the USB device was not connected.

*THOSE* are the possible devices for the 'mount' command you are trying.
