What mouse device is the X server using? If you tell it to use
"/dev/wsmouse", rather than "/dev/wsmouse0", it'll use the "mux"
(multiplex) of all the connected mice, including the USB mouse which
probably connects as "/dev/wsmouse1". By the way, you don't need to do
a suspend/resume just to connect a USB mouse. Just plug it in.
