Rob,
For good or bad, Mtools does not require that a file system be
mounted, and is unaware of mounts you may have done for the device.
It tries to emulate the DOS way of doing things, in which you do not
mount removeable media but just directly access them.
Mattrib is kind of a special case in that it does something unique
that you may not be able to do through a filesystem.
Probably the simplest thing to do is to redefine your drive a: or b:
in /etc/mtools.conf to point to the device your USB device shows up
as, and then give a path under that drive letter to mattrib. Use a
DOS file system, you end up with DOS semantics ;^)
If the device file varies unpredictably, I'm not quite sure how to
handle that but there is probably some reasonable way.

I guess this has something to do with the definitions used for floppy
disk devices not matching what is used by OS X in devices.c. While my
powerbook doesn't have one of course, the following is under the /dev
directory:
$ ls -l /dev/fd/

The USB key in question is mounted from /dev/disk2.
Am I using mattrib wrong or does this really require a programming
change? If so I'll see what I can do.
