yeah, that is a problem - I am pretty 'alone' in regard of linux users. I know
very few, and they have either only servers without X or run some stable
distributions with old kernels.

It is probably hardware related. I have tried two other mice and both were ok.
Both had a lesser resolution and were slower, but that shouldn't make any
difference.

I wanted to try some of the 32-rcs to see if they make any difference but the
reiser4 for 2.6.31 patch does not result in a buildable kernel anymore, thanks
to changes in writeback.h. So all I can say is:
2.6.31 is ok with the logitech, using ehci+hub+Translator settings and that is
good enough for me.
every other mouse is ok with either ohci or attached to the hub.
