two devices on one USB channel

I've bought a KVM switch (2computers->1display,mouse,keyboard(PS/2 
both)). It has one USB output (Windows sees USB mouse and USB keyboard).

I've rebuilt my kernel with this options:
options         KBD_INSTALL_CDEV
device          uhci
device          ohci
device          usb
device          ugen
device          uhid
device          umass
device          ukbd            # Keyboard
device          ums             # Mouse

Keyboard is working now. But mouse don't.

dmesg:
usb1: OHCI version 1.0, legacy support

moused is runned by usbd (/usr/sbin/moused -p /dev/ums0 -I 
/var/run/moused.ums0.pid ; /usr/sbin/vidcontrol -m on).

How can I fix it please?
