Hey everyone,

I have a FBSD 8.2 install.  I've been trying to mount DOS formatted 
floppy disks via a USB floppy drive, and have been getting the following 
error every time:

cannot mount /dev/da0: invalid argument

I was curious to see what would happen if I created a UFS filesystem on 
the floppy and tried to mount it.  So, I issued the following command:

newfs /dev/da0

It was successful.  I then tried to mount the new filesystem (mount 
/dev/da0 /mnt), and got the same error: invalid argument.  Does FBSD 
have a problem mounting USB floppy disks?  It's not a big deal, as my 
other USB storage devices seem to work, and as I have an ordinary floppy 
drive I can try, but that curious part of me wants to know why this 
isn't working.

I can provide dmesg output, if necessary.

Thanks!

James
