Hi Mike,

The good news is that Revolution lets you read from
and write to USB devices, with code similar to the
script below:
--
on mouseUp
  ## open a connection to the device
  open driver tDeviceName for binary read
  ## read three unsigned 32-bit integers 
  read from driver tDeviceName for 3 uint4
  ## do some more reading
  ## ...
  ## close the connection to the device
  close driver tDeviceName
end mouseUp
--

The bad news is that I haven't used it before, but I'm
sure there are others who would be happy to help you
with additional questions -- just wanted to inform you
that Revolution can do it.

Best regards,

Jan Schenkel.
