Sorry, will get that soon. But in the mean time, I do have a confirmed working
'driver' provided by the manufacturer, which I believe may be even more useful.

The driver was linked on this forum post -
http://forum.huiontablet.com/discussion/22/can-dwh69-work-on-linux/p1 but I
understand as a random dropbox link not everyone would want to download it. It
contains an 'idc' (for android) file, and instruction file which I replicate
below, and `huiontablet.c` which I've uploaded to pastebin here -
http://pastebin.com/ykCYrryL

The current Arch 4.7.2 kernel could not compile with the provided c file,
producing the following error:-

drivers/hid/huiontablet.c: In function ‘usb_mouse_irq’:
drivers/hid/huiontablet.c:100:3: error: implicit declaration of function ‘err’
[-Werror=implicit-function-declaration]
err ("can't resubmit intr, %s-%s/input0, status %d",
^~~

Simple fix, I just removed the call to 'err' and substituted printk (which was
commented out there, I believe 'err' is used in Android).

Note, I've cleaned up some chinese from the instructions file.

1 huiontablet.c [kernel]/drivers/hid
  Copy huiontablet.c to [kernel]/drivers/hid

2 Makefile
  Open Makefile ,before the end of file ,you can write

obj-$(CONFIG_HID_HUIONTABLET)   += huiontablet.o

3 Kconfig "drivers/hid/usbhid/Kconfig"
  Open Kconfig,after "drivers/hid/usbhid/Kconfig" (about Line 60),add

config HID_HUIONTABLET
        tristate "Huion tablet" 
        depends on INPUT
        ---help---
        Support for Huion tablet.

4 hid-ids.h
  Open hid-ids.h,before endif(about Line 675),add
#define USB_VENDOR_ID_HUIONTABLET 0x256C
#define USB_DEVICE_ID_HUIONTABLET 0x0005
#define USB_DEVICE_ID_HUIONTABLET2 0x006E

5 [kernel]/drivers/hid/usbhid hid-quirks.c
  Enter the folder [kernel]/drivers/hid/usbhid,open hid-quirks.c,in
hid_blacklist struct,before { 0, 0 }£¬add
        { USB_VENDOR_ID_HUIONTABLET,USB_DEVICE_ID_HUIONTABLET,
HID_QUIRK_IGNORE},
        { USB_VENDOR_ID_HUIONTABLET,USB_DEVICE_ID_HUIONTABLET2,
HID_QUIRK_IGNORE},

about Line 90

6 make menuconfig
Device Drivers-> HID Devices-> Huion tablet 
  open console and enter the kernel folder,
  make menuconfig
select Device Drivers-> HID Devices-> Huion tablet
