>As USB devices are connecting in a tree form, you can really easy specify the way keyboard and mice devices are bound to a specified X display. You have to use one USB hub with number of ports equal(or bigger) to the number of the X displays, to this hub are connected smaller (2-4 port) hubs (or keyboards with integrated hub). To the first port of the smaller (integrated) hub are connected the keyboards, to the second the mice (in case there are free ports you can connect usb-audio devices to them :) ). This results in the following layout of the usb-id's in case the primary USB hub is the first USB device :</P
