KVM Mouse and Keyboard not working

I use a KVM at home. I have Haiku r1b5 installed to a small itx PC connected to it. Haiku works really good but when I use the KVM it does not see the mouse or the keyboard. It will see any USB device I have in the one USB port the KBM has. Video is fine. Pc has no issues when mouse and keyboard are connected directly. Does anyone have any suggestions?
