Thanks Jim ;-)

The one I use is attached (/opt/ltsp/i386/etc/rc.d/usb). This is of
lesser-importance to me than the build_x4_cfg patch. There are a couple
of ways to load the mousedev USB module, any way that it is done will
work with the build_x4_cfg patch (which simply listens to both /dev/psaux
and /dev/input/mice). The old build_x4_cfg does not listen to/dev/input/mice
by default, so if the mousedev USB module happens to be loaded, USB mice
stop working. By having X listen to /dev/psaux and /dev/input/mice, USB
mice will work whether or not the mousedev USB module is loaded.

If the USB modules are not loaded, most bios will make a USB mouse
appear to be a standard PS/2 device on /dev/psaux. But if the USB
modules are loaded, that same mouse will be moved from /dev/psaux to
/dev/input/mice.

Basically the patch makes mice "just work", whether they are PS/2 or USB ;-)
