>Description:
My brand new ps/2 optical (800dpi) wireless mouse is moving rather jumpy around on the screen. Its perfect in windows. (PN535MA is a part of Labtecs ultra flat wireless mouse and keyboard bundle)
This problem is regardless if I use X alone or in combination with moused
I've tried disabling the probe by psm to detect which type it is:
hint.psm.0.flags="0x200" in device hints file. This actually helps alot, I wouldn't use the word perfect but definately a big improvement. The problem with this is that the wheel then stops working :o(
I've tried fiddeling with the resolution for moused but not getting any noticable improvement. I also tried specifying various protos for moused but it just defaults to generic.
I think it might be that FreeBSD is not sampling the mouse often enough? The mouse buttons doesn't always work on the first click, and I would say that aprox. 50 % of them come through - same thing with the wheel.

I don't know if there is anything openly wrong with this (I don't know anything about ps/2) but I know how to modify kernel / psm / moused code so I'll be happy to test stuff out. I can't stand it working in ms but not in fbsd
>How-To-Repeat:
              Sorry! I think you need to get this mouse in order to test it. I would definately consider paying if this would be needed. 
Otherwise you would just have to use it I guess.
>Fix:
              Guessing: increase the samplerate if it isn't IRQ driven.
