The problem is that you are dynamicaly loading the HID driver (Human Interface
Device).  This driver creates (in devfs) the /dev/input/mice.

You either need to load the driver manualy, so it won't be autocleaned.  Or
compile the USB interface driver and the HID driver staticaly in the kernel.

Even if you do not use devfs, you will have a problem.  Because, when X
connects to the "mice" device, it will get a "no such device" error, as
no loaded driver will have the major/minor combination claimed.
