I bought a keyboard that is shown on lsusb:

Bus 002 Device 009: ID 0c45:7603 Microdia

but the Ctrl, Windows/Super and Alt buttons are all mapped to Shift button. So I followed the hardware code and find this solution here, which works fine:

dkms status aziokbd
aziokbd, 1.0.0, 3.13.0-48-generic, x86_64: installed

However, after reboot, the keyboard goes back to original state( ctrl/alt/win mapped to shift) while dkms status is same as above, so I have to sudo dkms uninstall -m aziokbd -v 1.0.0 and install again.

How could I "save" the installed state? thank you.

I've ubuntu 14.04. Output of uname -a

Linux PC 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  • Could you reinstall it, when it's working, post output of: dkms status , lsmod | grep -e usbhid -e aziokbd and lsusb -t and same after reboot when it's not working. Also you may try add usbhid.quirks=0x0c45:0x7603:0x4 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub reference: unix.stackexchange.com/questions/55495/… . btw you need to run sudo update-grub – user.dz Apr 7 '15 at 9:43

    the grub command worked perfectly! Also I have posted the debug info without adding the grub command. Thanks for your help. – cstsangac Apr 7 '15 at 11:32

The usbhid still loaded as driver for the keyboard. It seems quirks didn't work as modprobe option.

  1. Try kernel option from grub, add:

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

    to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

  2. Update grub

    sudo update-grub
