Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)

Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
- stuff.

- Tip 'o the hat to IBM (and previously Linuxcare :) for supporting
