USB HID touchscreen (Penmount) status?

Hi,

I am trying to get Penmount touch screen controller into some usable
shape. As I used webcamd for touchscreen before, I thought it should
work. 'webcamd -l' tells me how it should be used, so trying running
'webcamd -N DIALOGUE-INC-PenMount-USB', but the result is

webcamd 10832 - - Attached to ugen0.2[0]
webcamd 10832 - - webcamd: Cannot find USB device

so no joy this way. By the way, I found some old patch for Linux at
https://patchwork.kernel.org/project/linux-input/patch/1408978083-569-1-git-send-email-christian.gmeiner@gmail.com/
and, given the date, it should be probably included in standard Linux
sources, so webcamd should know it, but there is something wrong.

So I tried another route, using sysutils/uhidd port. Installing it,
running 'uhidd -hkmou -dDvvv /dev/ugen0.2' shows me touch events, I
just see nothing in X. Starting uhidd this way outputs

uhidd 10933 - - open /usr/local/etc/uhidd.conf failed: No such file or directory
uhidd 10933 - - proceed without configuration file

so that's great. How can I feed the event into X? I tried running uhidd
with -H option to create a device, but I have no idea how could
xf86-input-libinput driver accept it - device from uhidd is probably
not proper input/event device, even if I request the name be like this.

Any hint here? Googling did not reveal anything I could understand and
use :)
