VEIKK Linux Driver
A driver for VEIKK-brand digitizers/drawing tablets using the usbhid API.
Configuration options are exposed in sysfs and configurable with an associated
GUI. Connects low-level hardware events to the input subsystem (e.g.,
libinput), with some processing/mapping logic in between. This draws heavily
from the Wacom driver for Linux.
Features:
Currently, a set of basic basic digitizer features are supported, such as:
- Full range and resolution for tablet pressure and spatial sensitivity
- Configurable screen mapping, orientation, and (cubic) pressure mapping
- Driver (using
/etc/modules-load.d/) and options (using/etc/modprobe.d) persist after reboots
More features are planned for the near future, such as:
- Button remapping
- Support for gesture pads and additional buttons (model-dependent)
- Device/model-specific configuration options
Installation
Make sure you have make and the appropriate linux headers installed
(linux-headers-$(uname -r) on Ubuntu, linux-headers on Arch). See this
for more details.
make
sudo make all install clean
If you are getting a Required key not available error, please see
this issue.

AUR (dkms) package
Thanks to @artixnous, this driver is available as an AUR package with
dkms! See input-veikk-dkmsAUR. Make sure to run
modprobe veikk after installation to load the driver.
Uninstallation
sudo make uninstall
Configuration
Currently, the configurable parameters are screen_size, screen_map,
orientation, and pressure_map, and are all available in sysfs under
/sys/module/veikk/parameters with permissions 0644. Documentation on the
parameters is available in veikk_modparms.c. You can update a parameter
by simply writing the new value to it as root.
The (new!) visual configuration utility is available at @jlam55555/veikk-linux-driver-gui.
Changelog:
- v2.0: Renamed from veikk-s640-driver, redesigned from the ground up to be more extensible.
- v1.1: Basic command-line configuration utility is created! Includes ability to change tablet orientation, mapping onto section of screen, and mapping raw pressure input to pressure output.
- v1.0: Basic digitizer capabilities (e.g., pressure sensitivity) for S640 and similar tablets.
Development status
Currently, development is focused on the S640, but PR's are welcome. The developer only has an S640 at the moment and is unable to directly develop new features for other models, but open to feedback and questions at jonlamdev at gmail dot com.
