Keyspan usa 28xb drivers

Date: Fri Feb 21 2003 - 12:28:28 EST

This is the drivers from TrippLite's website for the Keyspan USA-28x USB to serial adapter. I downloaded them from TrippLite's site because there's no longer. FAQ: Newer PCs and laptops lack an RS232-C interface. The Keyspan USB adaptor emulates this port and allows X-Rite serial instruments to function.

Please excuse my mistakes. That was my very first post to the list even
though I've been reading it for many years. I wasn't entirely sure how to
get this out there. I'm glad you noticed it Greg :)

You're right. the Config.in file didn't need all those changes. I mistakedly
diffed against the wrong file.

The 49WLC device works fine with this patch. I have not tested the MPR but
it should work too.

Below is a better patch.

Change History
+ Wed Feb 19 22:00:00 PST 2003 (Jeffrey S. Laing <'>keyspan@jsl.com>)
+ Merged the current (1/31/03) Keyspan code with the current (2.4.21-pre4)
+ Linux source tree. The Linux tree lacked support for the 49WLC and
+ others. The Keyspan patches didn't work with the current kernel.
+
+ 2003jan30 LPM add support for the 49WLC and MPR
+
+ Wed Apr 25 12:00:00 PST 2002 (Keyspan)
+ Started with Hugh Blemings' code dated Jan 17, 2002. All adapters
+ now supported (including QI and QW). Modified port open, port
+ close, and send setup() logic to fix various data and endpoint
+ synchronization bugs and device LED status bugs. Changed keyspan_
+ write_room() to accurately return transmit buffer availability.
+ Changed forwardingLength from 1 to 16 for all adapters.
+
+ Fri Oct 12 16:45:00 EST 2001
+ Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV)
