wacom on X1 Yoga 3rd generation not detected

[Mathias Picker]

Hi all,

webcamd says that a wacom stylus should be automatically detected 
by devd.
This does not work on my 3rd gen X1 Yoga on 12-stable

I’ve installed
xf86-input-evdev-2.10.6_4
xf86-input-wacom-0.37.0
webcamd-5.3.7.1

and enabled webcamd with webcamd_enable="YES" in /etc/rc.conf

I can configure the stylus manually, but this is problematic on 
the X1 Yoga, since all inputs are removed when I close the lid and 
reconnected when I open it again, and for wacom I get new device 
entries /dev/input, so the manual configuration will no longer 
work.

I’m running FreeBSD Danton 12.1-STABLE FreeBSD 12.1-STABLE r353466 
GENERIC  amd64

Any idea how to debug and/or fix this would be great!

Thanks,

Mathias

P.S. More info:

Closing the lid looks like this in /var/log/messages:
Oct 15 21:27:43 Danton kernel: ugen0.5: <Wacom Co.,Ltd. Pen and 
multitouch sensor> at usbus0 (disconnected)

and this happens on opening:

multitouch sensor> at usbus0

Without manual configuration the device is seen by libwacom:
