I am left-handed and share certain devices with my right-handed SO. I bought the Corsair M55 which seems adequate as a middle-tier shareable device given its symmetric design and the two (four) "thumb-buttons" for both left-handed and right-handed configurations.

However a xinput --test <id> shows that:

  • Buttons 1-2-3 are standard (I plan to remap 1 and 3 for left-handed usage in my account).
  • Buttons 4-5 are wheel buttons.
  • Right-handed thumb buttons (those that are physically on the left side of the mouse) are 8 and 9.
  • Left-handed thumb buttons (physically on the right side of the mouse) don't trigger anything.

How can I use those buttons? Why are they not triggering any xinput event? Have I missed any step?

Without drivers only one side of the thumb buttons is active at the time. You can switch sides by holding both thumb buttons for three seconds:

  • To switch to left-handed mode press both buttons on the left side
  • To switch to left-handed mode press both buttons on the right side

Switching is signalized by blinking DPI LED, its persistent, and left-handed mode also swaps left-right mouse buttons
