Just be sure that USB is configured into your Linux kernel. This is the case by
default if you're using any reasonably up-to-date release of any of the
commonly available distributions.

BRLTTY does support the PAC Mate. Invoke it like this:

   brltty -b fs -d usb:

Specifying "-b fs" selects the FreedomScientific driver. Specifying "-d usb:"
(that trailing colon is significant and must be specified) tells BRLTTY to look
for the display on the USB. If you'd like to invoke BRLTTY without having to
specify those options all the time, create the file "/etc/brltty.conf" and put
the following two lines in it:

   braille-driver fs
   braille-device usb:
