You are missing the "HUION PenTablet Pad pad" interface...

... which is created here.

[edit: keeping this part for documenting purpose, this is not required
right now, we would have to update the xf86-input-wacom driver first.
See below]

So actually, you are just missing a udev rule to properly tag the device
as a ID_INPUT_TABLET:

[bentiss@plouf ~]$ cat /etc/udev/rules.d/65-digimend.rules 
# udev rules for digimend devices

ACTION!="add|change", GOTO="digimend_end"
KERNEL!="event[0-9]*", GOTO="digimend_end"

ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="256c", ENV{ID_MODEL_ID}=="006e",
ENV{ID_INPUT}="1", ENV{ID_INPUT_JOYSTICK}="", ENV{ID_INPUT_TABLET}="1"
ATTRS{name}=="* Pad", ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="256c",
ENV{ID_MODEL_ID}=="006e",  ENV{ID_INPUT_TABLET_PAD}="1"

LABEL="digimend_end"
[bentiss@plouf ~]$

Then run "sudo udevadm control --reload "

With this rule, "udevadm info --exportdb" should show the event node
"HUION PenTablet Pad" tagged with ID_INPUT_TABLET_PAD=1.

Then, xinput should show up the "HUION PenTablet Pad pad" device.
If it does not, then you will have to send me the Xorg.log when you
plug the tablet.

No, the kernel will be fine. It's the userspace which will consider all
"HUION PenTablet" as H610 Pro and will show the same UI for configuring
the tablet. It's not a problem for the stylus part, but it will be one
for the buttons of the tablet (what we refer to pad).

The pad interface :)

Oh. Actually, you also need to add a patch in xf86-input-wacom :(
Without it, the pad will be rejected by the driver while it could work
just fine.

I'll send a patch to digimend-kernel-tree to make the pad interface
looks like an old legacy Wacom pad so that you will be able to continue
the tests. Sorry for that.

You can definitively ignore Mouse and Consumer Control. We keep them in
the kernel because we don't know if they are used by any tablet, given
that it looks like there is no reliable way to know which tablet is
which.

OK. So it's best to wait for the update on the driver first. With this
update, you won't even need the udev rule.

I'll do that tomorrow.
