A system service to make the Huion graphical tablets functional on FreeBSD.
Confirmed to work with:
- H420
- H950P
- H952 (thanks to @tingox)
- Kamvas 20 (thanks to @sterentev)
May work with other Huion devices, let me know if it does.
Make sure CUSE and Webcamd are enabled in your system.
To use the service, copy it to the service folder:
# cp huion /usr/local/etc/rc.d/
Add the service to rc.conf:
# sysrc huion_enable=YES
Then, either reboot, or start the service with
# service huion start
FreeBSD and moused in particular detect the tablet as a USB mouse by default, creating a /dev/ums device. However, since the tablet is not a USB mouse, this does not work and it prevents webcamd from attaching to the tablet properly.
This service adds a USB quirk that prevents FreeBSD from creating the broken /dev/ums device.
Since the quirk is added via vendor ID, it is possible that this would work for most Huion devices.
