Mouse dind't work ...

Do you know for a fact that the rodent works? Open a terminal and inputtail -f -n0 /var/log/syslogNow do you get any output when you plug it in/out?

Yes this: (First I output my mouse that work, then i plug the new mouse on, test it and after this put the working mouse again in)

You didn't say whether you know that thing works.

Looks like it's suggested that modprobe -r ehci_hcdmight help.

Apparently it's a hardware problem. Note that this will retard all your USB port traffic from 2.0 to 1.x making them slower.

Sry for this post ...
I testet the mouse now on a other computer and there it doesn't work too.
So the problem should be on the mouse.
Thank you for your help.

Either a USB mouse or a PS/2 mouse would cost less than an adapter ... anyway, get plenty of spares.
