KVM switch problem with mouse

[Ivan Carey]

Hello,
I'm using FreeBSD 5.3
I'm using a MC2050, MC2060 2 port auto kvm switch.
My mouse does not work either at the console or in KDE, the keyboard is ok.

Is there a command I need to place into the kernel to get the mouse driver 
to recognise the mouse via the KVM switch?

Thanks,
Ivan
