Hi.

	I got a usb touch screen device A.K.A. eGalax.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
ugen4.4: <USB TouchController eGalax Inc.> at usbus4, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	In this time, however, FreeBSD doesn't support usb touch screen.
	So I researched Linux's (drivers/input/touchscreen/usbtouchscreen.c)
	and NetBSD's (uep(4)) implementations.  It's too simple.

	I considered making modified ums(4) to adapt usb touch screen.
	But I noticed that ums(4) should be become a mouse subsystem
	like ucom(4), and I gave up:-).  Anyone, do you have any idea?
