Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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 :) |

| 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 |
