Hi,

I'm trying to get an eGalax USB touchscreen working on FreeBSD 
13.0-RELEASE and several approaches have been unsuccessful.

1) uep(4) in evdev or native mode - uep.ko automatically loads and 
attaches. X uses the respective evdev or egalax input driver however no 
events are registered with `xinput --test` or evemu-record. [1] suggests 
uep(4) is for older non-HID devices and the vendor reused the same 
device IDs for newer HID devices, so a different driver may be correct 
for this device. [1] 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=183032

ugen0.3: <eGalax Inc. USB TouchController> at usbus0
uep0: <eGalax Inc. USB TouchController, class 0/0, rev 1.10/1.00, addr 
3> on usbus0

2) uhid(4) - With uep(4) disabled, uhid(4) attempts to attach but fails:

kernel: ugen0.3: <eGalax Inc. USB TouchController> at usbus0
kernel: uhid1 on uhub1
kernel: uhid1: <eGalax Inc. USB TouchController, class 0/0, rev 
1.10/1.00, addr 3> on usbus0
kernel: uhid1: no report descriptor
kernel: device_attach: uhid1 attach returned 12

3) uhidd(8) - With uhid(4) disabled, this is the only method that any 
touchscreen events have been seen but there are issues. Sometimes 
starting uhidd will fail the first couple times 
("libusb20_dev_request_sync failed" the first, crash the second) and 
then start OK after a few tries. When it is running uhidd prints 
touchscreen events with -v but X didn't autodetect the /dev/uvhid* 
device or if symlinked to /dev/uhid*. If the X "mouse" driver is 
configured with the uvhid device X will segfault upon startup citing 
mouse_drv.so.

4) wmt(4) - wmt.ko automatically loads but does not attach or create any 
evdev devices.

5) `webcamd -l` shows the device but exits on startup with "Cannot find 
USB device".

Should this device work with uhid(4) or wmt(4) and does the below output 
give any clues what might be going wrong? If uhidd(8) or webcamd is what 
should be used instead are there any issues with my config?

The device itself should be okay, it works out of the box on OpenBSD and 
the vendor provides drivers for Linux.

Thanks in advance for any pointers.

-Mark
