Some I time ago I sended the oops or ayiii (what is the difference, it was an 
ayiiii)

The list told me that I should use ksysmoops.

The problem doesn't come up if I plug the mouse in the usb hub of the 
keyboard.
Everything works well if it is in the first port, only the second makes the 
problem.

I hope I can reproduce it later today and run ksysmoops to get some 
information.

thanks
have fun
Felix
