this has been driving me nuts for a long time. i've had to have a mouse for each machine running rio because mouse.c wasn't very amenable to either hot-plugged ps/2 or kvm-attached ps/2 mice. since steve mentioned the led problem, i was motivated to finally rid my desk of extra rodents: /n/sources/contrib/quanstro/mouse.c
the approach is - turn off streaming mode when sending commands, - always set 1:1 aka "linear" mode. much loved by iogear kvm. - don't use 2:1 mode (unloved by kvms and it confuses some fancy mice). trivial to simulate in s/w. - capture power-on signatures and set hot-plugged mice up in streaming mode. thanks for the motivation, steve. - erik
