It depend what you call button functionality. My goal is to get rid of
the keyboard shortcuts that are emitted by the device out of the box. It
is a really bad idea from the firmware engineers and you don't get the
release information on each button.

If you are using the branch huion-abstract-keyboard on the
digimend-kernel-drivers tree, then this is what we should end up.

Currently these patch series give little enhancement with respect to
what is currently upstream (these are upstream patches).

The only difference from what you will get from a plain v3.19 kernel is
that there will be some suffixes added to the name of the input nodes
(some more appeared because we can not be sure that we don't need them).
On my H610 Pro, I have:

$ xinput
â Virtual core pointer                    	id=2	[master pointer (3)]
â   â HUION PenTablet Pen                     	id=9	[slave  pointer (2)]
â   â HUION PenTablet Mouse                   	id=10	[slave  pointer (2)]
â Virtual core keyboard                   	id=3	[master keyboard (2)]
    â HUION PenTablet Keyboard                	id=11	[slave  keyboard (3)]
    â HUION PenTablet System Control          	id=12	[slave  keyboard (3)]
    â HUION PenTablet Consumer Control        	id=13	[slave  keyboard (3)]

Of course, I receive events only on the Pen and Keyboard interface.

I just pushed the 6 patches of the v2 series on top of a v4.0-rc1 kernel
merged with Jiri's tree (the official hid tree):
https://github.com/bentiss/linux branch huion.v2-4.0-rc1

But that means that you need to recompile the whole kernel for the
tests. You can try to copy/paste drivers/hid/hid-uclogic.c into your
local digimend-kernel-drivers tree and then run make. Depending on your
running kernel, it might work, or not :(

When this will be merged upstream, I'll send the equivalent patches for
the digimend tree, plus the rebase of huion-abstract-keyboard on top of
that.

Cheers,
Benjamin
