Those above errors seem to be the important ones. Starting with the Xorg
log:
[ 109.592] (EE) ws: /dev/wsmouse1: SCALIBCOORS failed Inappropriate
ioctl for device
That comes from sys/dev/wscons/wsmouse.c, `wsmouse_do_ioctl': it passes
down to the mouse driver.
The mouse driver in this case is ums(4) (not uts(4)) in the function
`ums_ioctl'. This in turn passes off to `hidms_ioctl'
(dev/usb/hidms.c), which should handle WSMOUSEIO_SCALIBCOORDS without
issue, but:
ums1 at uhidev0 reportid 7
ums1: mouse has no X report
This comes from dev/usb/hidms.c, `hidms_setup', which is called from
`usm_attach' back in ums.c . Without a successful, `hidms_setup', the
`hidms_attach' function is never called. Presumably, this is the source
of all my problems. But back to the uts(4) idea:
uhidev0 at uhub3 port 3 configuration 1 interface 0 "eGalax Inc.
eGalaxTouch EXC7903-66v03_T1" rev 2.00/66.03 addr 3
This makes me think it should use the uts(4) driver, not ums(4).

So that's what I know so far. This makes me think there are two items to
fix:
1. If `hidms_setup' fails, the device should be disabled. This is to
prevent issues like the one I ran into, where Xorg.0.log fills with
errors.
2. Adding support for the touchscreen.
I'll gladly try this but it'd be great if I could get some pointers on
how to begin. For (1), should `hid_locate' be called from within
`ums_match'? For (2), is it as easy as adding some constants to
`uts_devs'?
