Keyboard stop working

Question

I have a Corsair Gaming Strafe MX keyboard is not detected by Ubuntu 16.04. After grub when I have to login the keyboard and mouse doesn't work. After login by using another keyboard and a few seconds my mouse starts working again. But the keyboard does not. I know it gets power because the leds on it lights up.

I got this problem after I install xpad to get my xbox one controllers to work. So I tried to remove xpad but still have problem with my keyboard.

My mouse have worked fine before but I sometimes had problem with that I had to unplug and plugin the keyboard again.

Edit:

I get following message in dmesg when pluging it out and in again.

I have the same issue using Corsair K70 LUX... I regain the keyboard by plugging it out and back in after reboot. However it stays 'connected' during sleep sessions.

Answer 2

This is a well known problem with Corsair keyboards, and as yet there are workarounds but no real solution. You might want to look at ckb-next for some workarounds and a driver that might help:

scroll to the "Troubleshooting" section and look for Linux.

I have had reasonable success by adding the following to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.quirks=0x1B1C:0x1B13:0x20000408,0x1B1C:0x1B12:0x20000408,0x1B1C:0x1B20:0x20000408"

After you add this, run:

sudo update-grub

to record the changes, then reboot.
