14 | Code in this driver inspired by and in a number of places taken |
15 | from Brian Warner's original Keyspan-PDA driver. | |
16 | ||
17 | This driver has been put together with the support of Innosys, Inc. | |
18 | and Keyspan, Inc the manufacturers of the Keyspan USB-serial products. | |
19 | Thanks Guys :) | |

21 | Thanks to Paulus for miscellaneous tidy ups, some largish chunks |
22 | of much nicer and/or completely new code and (perhaps most uniquely) | |
23 | having the patience to sit down and explain why and where he'd changed | |
deb91685 AC |
24 | stuff. |
25 | ||
26 | Tip 'o the hat to IBM (and previously Linuxcare :) for supporting | |
1da177e4 | 27 | staff in their work on open source projects. |
