Hi,
The attached (mostly trivial) patches adds support for the Evolution
Scorpion Robots. The patch is against 2.6.20. I tried to follow patch
style in Documentation/SubmittingPatches, but to be honost I can't
figure most of it out (guess I'm stupid, but that's okay).
Evolution Robotics supplies a patch against 2.6.8 with their
software. My patch is based on their work, so I don't know if I can
sign it off, or if you need some Evolution people to do this (which
might be hard).
The patch adds device ID's for some robots which is trivial. The
only non-trivial part of the patch is the part that changes the baud
rate of the device if it is an Evolution product. I don't know if this
is done in the correct place according to the flow of the program. (As
you can tell, I'm not really a kernel hacker...)
I'm sorry if I don't provide everything you usually require, but as I
said, I'm not really a kernel guy :-)
Søren
