SubjectRe: 2.3.51 tulip broken
/ANOTHER SOAPBOX ON/

I have been following and using Donald's tulip.c for MANY YEARS...

I totally agree with Jim Morris. Let's stop the wasteful
complaining!!!! I'll bet most of us are tired hearing it!

Donald has worked hard to maintain a driver for "tulip", while, in fact,
there is NO "tulip" standard. Manufacturers have changed the guts of
the original "tulip" design in a willy-nilly fashion - without warning
(no new board/card designation changes). Donald has "busted his rump"
to keep up with all the changes - and simultaneously improve performance
of the driver.

Have there been problems, you bet. But Donald has responded over the
years as best as one could expect. Could he use a hand? Of course.
How about working together instead of this ridiculous, undermining
criticism!
