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 :) | |
20 | ||
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 | |
24 | stuff. | |
25 | ||
26 | Tip 'o the hat to IBM (and previously Linuxcare :) for supporting | |
27 | staff in their work on open source projects. | |
28 | ||
29 | Change History | |
30 | ||
31 | 2003sep04 LPM (Keyspan) add support for new single port product USA19HS. | |
32 | Improve setup message handling for all devices. | |
33 | ||
34 | Wed Feb 19 22:00:00 PST 2003 (Jeffrey S. Laing <keyspan@jsl.com>) | |
35 | Merged the current (1/31/03) Keyspan code with the current (2.4.21-pre4) | |
36 | Linux source tree. The Linux tree lacked support for the 49WLC and | |
37 | others. The Keyspan patches didn't work with the current kernel. | |
38 | ||
39 | 2003jan30 LPM add support for the 49WLC and MPR | |
40 | ||
41 | Wed Apr 25 12:00:00 PST 2002 (Keyspan) | |
42 | Started with Hugh Blemings' code dated Jan 17, 2002. All adapters | |
43 | now supported (including QI and QW). Modified port open, port | |
44 | close, and send setup() logic to fix various data and endpoint | |
45 | synchronization bugs and device LED status bugs. Changed keyspan_ | |
46 | write_room() to accurately return transmit buffer availability. | |
47 | Changed forwardingLength from 1 to 16 for all adapters. | |
48 | ||
49 | Fri Oct 12 16:45:00 EST 2001 | |
50 | Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV) | |

59 | ||
60 | Fri Oct 12 16:45:00 EST 2001 | |
61 | Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV) | |
62 | ||
63 | Mon Oct 8 14:29:00 EST 2001 hugh | |
64 | Fixed bug that prevented mulitport devices operating correctly | |
65 | if they weren't the first unit attached. | |
66 | ||
67 | Sat Oct 6 12:31:21 EST 2001 hugh | |
68 | Added support for USA-28XA and -28XB, misc cleanups, break support | |
69 | for usa26 based models thanks to David Gibson. | |
70 | ||
71 | Thu May 31 11:56:42 PDT 2001 gkh | |
72 | switched from using spinlock to a semaphore | |
73 | ||
74 | (04/08/2001) gb | |
75 | Identify version on module load. | |
76 | ||
77 | (11/01/2000) Adam J. Richter | |
78 | usb_device_id table support. | |
79 | ||
80 | Tue Oct 10 23:15:33 EST 2000 Hugh | |
81 | Merged Paul's changes with my USA-49W mods. Work in progress | |
82 | still... | |
83 | ||
84 | Wed Jul 19 14:00:42 EST 2000 gkh | |
85 | Added module_init and module_exit functions to handle the fact that | |
86 | this driver is a loadable module now. | |
87 | ||
88 | Tue Jul 18 16:14:52 EST 2000 Hugh | |
89 | Basic character input/output for USA-19 now mostly works, | |
90 | fixed at 9600 baud for the moment. | |
91 | ||
92 | Sat Jul 8 11:11:48 EST 2000 Hugh | |
93 | First public release - nothing works except the firmware upload. | |
94 | Tested on PPC and x86 architectures, seems to behave... | |
