  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 
  staff in their work on open source projects.
  
  See keyspan.c for update history.
