Linux Microdia Keyboard Chipset Driver

For Chipset 0x0c45:0x7603 The kernel reports the chipset as SONiX USB Keyboard

Written for the Azio L70 USB Keyboard: L70 USB Backlit Gaming Keyboard (KB501)

NOTE: Makefile and instructions are only tested on Ubuntu, however they are known to work on Debian, Arch, Fedora, and Manjaro.

Reports suggest it supports the following keyboards as well:

SL-6432-BK - Speedlink LUCIDIS Comfort Illuminated Keyboard
COUGAR 200K Scissor Gaming Keyboard
GAMDIAS USB Keyboard (unspecified model but will report as Microdia chipset)
Avazz USB Keyboard (unspecified model but will report as Microdia chipset)
Perixx P1800
Modecom MC800-Volcano
Serioux Radiant KBL-003
SEISA DN-V370 multimedia keyboard

Manual Install

sudo apt-get install git build-essential linux-headers-generic
git clone https://github.com/Swoogan/aziokbd.git
cd aziokbd
sudo ./install.sh

Blacklisting

NOTE: install.sh attempts to blacklist the driver for you. You shouldn't need to do anything manually. These instructions are to explain the process, in the event something goes wrong.

You need to blacklist the device from the generic USB hid driver in order for the aziokbd driver to control it.

Kernel Module

If the USB hid driver is compiled as a kernel module you will need to create a quirks file and blacklist it there.

You can determine if the driver is a module by running the following:

lsmod | grep usbhid

If grep finds something, it means that the driver is a module.

Create a file called /etc/modprobe.d/usbhid.conf and add the following to it:

options usbhid quirks=0x0c45:0x7603:0x0004

If you find that the generic USB driver is still taking the device, try changing the 0x0004 to a 0x0007.

Compiled into Kernel

If the generic USB hid driver is compiled into the kernel, then the driver is not loaded as a module and setting the option via modprobe will not work. In this case you must pass the option to the driver via the grub boot loader.

Create a new file in /etc/default/grub.d/. For example, you might call it aziokbd.conf. (If your grub package doesn't have this directory, just modify the generic /etc/default/grub configuration file):

GRUB_CMDLINE_LINUX_DEFAULT='usbhid.quirks=0x0c45:0x7603:0x4'

Then run sudo update-grub and reboot.

Again, if you find that 0x4 doesn't work, try 0x7.
