The device I want to disable has id 13. Use xinput to list its properties:
xinput -list-props 13
Device ‘DualPoint Stick’:
Device Enabled (117): 0
[…several lines removed…]
xinput -set-prop 13 117 0
Once I knew the solution, I could easily find other posts that mentions it. But what good is that?🙂
Actually, the device is is dynamically allocated, and can change. So a better command to disable the stick is:
xinput -set-prop "DualPoint Stick" "Device Enabled" 0
