What is the current state of drawing tablet support?

Wacom Intuos S works ok via evdev on 12.2-p6, with one caveat - at least that's valid for mine: you need to have it plugged in during boot and keep it that way. Once you unplug and plug it in again, the device only seems to get power but isn't properly initiated. Needs a reboot to get it working again. Your mileage may vary with other models and different hardware/USB bus, obviously.

I believe I somehow still needed x11/xinput for it to run, but can't say for sure; it's been a while since I set mine up. Otherwise, apart from having x11-drivers/xf86-input-evdev, no config or particular addon was required,
 
FWIW, I have just got a Huion Inspiroy H952 (drawing) tablet working under FreeBSD 13.1-release. I installed xf86-input-evdev (which brought in webcamd) and xinput, enabled cuse by adding it to kld_list="..." in /etc/rc.conf. I also added webcamd_enable="YES" to rc.conf. Finally, I added the following lines to /usr/local/etc/devd/webcamd.conf:
Code: 
# add Huion tablets
notify 100 {
        match "system"          "USB";
        match "subsystem"       "INTERFACE";
        match "type"            "ATTACH";
        match "intclass"        "0x03";
# limit to vendor match
        match "vendor"          "0x256c";
        action "/usr/local/etc/rc.d/webcamd start $cdev $interface 2>/dev/null";
};
to have webcamd start up automatically when the tablet is plugged in. Oh yes, I also added my user to the webcamd group. The tablet works in GIMP and Xorg, but in Xorg the default mode is select which is not that useful. Also the two buttons on the pen is mapped to middle and right button. I suspect this can be changed with xinput or something.
 
xinput reports
Code: 
tingo@kg-core1:~ $ DISPLAY=:0.0 xinput list
⎡ Virtual core pointer                        id=2    [master pointer  (3)]

and /var/log/Xorg.0.log is filled with lines like these

that's all for now.

thanks, I did both of your post so I am not sure which one worked after I rebooted now my Huion H950P is working . (FreeBSD 13.1 fresh install)

install:

and
xf86-input-evdev

follow post #6



now I just need to get my Bluetooth running for ear buds, but its late now....

I just tested the huion-freebsd (see post #9) with my Inspiroy H952, and it does have an effect. Without it, /var/log/messages shows

the H952 works both with and without this. The machine I',m testing on runs
Code: 
root@kg-core1:~ # freebsd-version -ku
13.3-RELEASE-p7
13.3-RELEASE-p8
root@kg-core1:~ # uname -a
FreeBSD kg-core1.kg4.no 13.3-RELEASE-p7 FreeBSD 13.3-RELEASE-p7 GENERIC amd64
 
and pressure works in GIMP (you have to enable the pencil on the tablet first, then you have to enable "pressure opacity" under Dynamics for the brush or tool you are using).

I am thinking to buy it now on Amazon and I hope that will work on Inkscape too and I hope pressure too.
Do you have any other problems, please?
TY
 
With a Wacom CTH-470 on FreeBSD 14.2-R p2 (Xfce, X11), I went to GIMP, Paintbrush Tool -> Basic Dynamics, and I get different brush darkness shades when applying pressure; I'm not sure if there's some debug window that shows the pen pressure stats real-time, but it looks like it works fine! (had it over a year and never tested pen pressure until now :p)

I'm forcing evdev instead of wacom:

Code: 
Section "InputClass"
    Identifier "Wacom CTH-470 (evdev custom)"
    MatchUSBID "056a:00de"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev"
    Option "Mode" "Absolute"
    Option "AccelerationProfile" "-1"
    Option "AccelerationScheme" "none"
EndSection

Tested just now. Pressure works in Inkscape (Inkscape 1.4) using the Pencil and Calligraphy tool. It probably works with the Pen tool, but I'm no Inkscape expert.
I didn't have to change any settings, just plug in the tablet, and Start Inkscape.

None that I have discovered so far.

Thank you. I will order tomorrow Huion Inspiroy H952 like yours :).
