Mouse not working via KVM switch

[Karel Lucas]

HI all,
On a recent install of openBSD I can't get the mouse to work through my 
KVM switch. I work with various computers via a KVM switch on 1 monitor 
with a keyboard/mouse combination. Only on the PC with openBSD the mouse 
does not work, the keyboard on the other hand works fine. Both are 
connected to the KVM switch via USB, and the switch via USB to the 
computers. The brand of the mouse is Logitech. Does anyone know why the 
mouse doesn't work, but the keyboard does?
