I believe that would defeat the purpose. The whole point of the mutex is to 
protect the USB device from simultaneous access from two processes, e.g. the 
reader process and the main process. If the key to create the mutex is 
different in both processes they end up with different mutexes and the USB 
device is unprotected.

Anyway, I've commited a hash function now. The new code should also work on 
FreeBSD 8.0. If anyone can try it, I'd be much obliged.

Kind regards,

Oliver
