Well, not exactly 'lose compatibility' as much as change the way the drivers are structured; but yes even the ubiquitous USA-19HS - that rock-solid bastion of Apple support - was affected by the changes in Big Sur. In the long run it is for the better, but there will be some pain in the short term obviously. (on/off) USB Keyspan USA-28XB Firmware; depends on USBSERIALKEYSPAN Say Y here to include firmware for the USA-28XB converter. Be sure you have a USA-28XB, there are also 28X and 28XA models, the label underneath has the actual part number. Option: USBSERIALKEYSPANUSA19 Kernel Versions: 2.6.15.6. (on/off) USB Keyspan USA-19.

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.

+ Wed Apr 25 12:00:00 PST 2002 (Keyspan)

+ 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)
