usb giving me a huge headache

i recently got gentoo up and running on my system, but for the life of me i cant get my usb devices to work. i have a usb keyboard that acts as a usb hub, which i plug my usb mouse into. the keyboard's plugged into a belkin usb switch, which is plugged into both of my computers. i was able to get the keyboard and moouse to work under debian, but not under gentoo. here's my current xorg.conf file (i've tried a number of different things, but no dice):

Section "InputDevice"
Identifier "Keyboard0"
Driver "kdb"
EndSectoin

Section "InputDevice"
Identifier "USB Mice"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Buttons" "5"
EndSection

anybody have any thoughts? thanks a bunch.
