10 Code in this driver inspired by and in a number of places taken
11 from Brian Warner's original Keyspan-PDA driver.
13 This driver has been put together with the support of Innosys, Inc.
14 and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
17 Thanks to Paulus for miscellaneous tidy ups, some largish chunks
18 of much nicer and/or completely new code and (perhaps most uniquely)
19 having the patience to sit down and explain why and where he'd changed
22 Tip 'o the hat to IBM (and previously Linuxcare :) for supporting
23 staff in their work on open source projects.
