I’ve been using Linux based operating system for a long time and I am Steam player.

I’ve recently bought Redragon ASURA K501 USB Gaming Keyboard from Amazon India website. I found that Ctrl, Alt and Win keys are mapped to Shift.

I modified a Linux driver from existing gaming keyboard driver suited for Redragon Asura K501 and uploaded in bitbucket.

The issues resolved:

  • Ctrl, Alt and Windows keys not working.
  • Ctrl and Alt keys mapped to Shift key.

Here are the steps to get the keyboard working on most of the Linux based distributions.

For Debian Based Systems

sudo apt-get install mercurial build-essential linux-headers-generic dkms

fedora:

sudo dnf install kernel-devel kernel-headers
sudo dnf groupinstall "Development Tools" "Development Libraries"

Common steps for both

hg clone https://[email protected]/nayabbashasayed/redragonkbd
cd redragonkbd
make clean
make
sudo ./install.sh

Search for GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub file and replace that line with the following line.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.quirks=0x0c45:0x760b:0x4"

Update the grub

sudo update-grub
reboot

Note: If you update your kenel (or opearating system), keyboard might not work and you need to do the whole procedure again.
