Determine the Mouse to use

xinput --list --short

returns: 

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Consumer Control	id=11	[slave  pointer  (2)]
⎜   ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Mouse	id=12	[slave  pointer  (2)]
⎜   ↳ Razer Razer DeathAdder V2               	id=8	[slave  pointer  (2)]
⎜   ↳ Razer Razer DeathAdder V2 Consumer Control	id=9	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard	id=10	[slave  keyboard (3)]
    ↳ Corsair CORSAIR K70 RGB MK.2 Mechanical Gaming Keyboard Consumer Control	id=13	[slave  keyboard (3)]
    ↳ Razer Razer DeathAdder V2 Consumer Control	id=14	[slave  keyboard (3)]
    ↳ Razer Razer DeathAdder V2 Keyboard      	id=15	[slave  keyboard (3)]
    ↳ Razer Razer DeathAdder V2 System Control	id=16	[slave  keyboard (3)]
    ↳ Razer Razer DeathAdder V2               	id=17	[slave  keyboard (3)]

NOTE: In this case, the “Razer Razer DeathAdder V2” is the mouse.

  • As there are multiple entries, the name “Razer Razer DeathAdder V2” cannot be used as it is not unique.
  • Instead, use the id.
    • How to know which of the id to use.

Which id to use

In the above results, the Razer DeathAdder is shown multiple times. 

xinput | grep -m 1 "DeathAdder"

returns: 

⎜   ↳ Razer Razer DeathAdder V2               	id=8	[slave  pointer  (2)]

NOTE: Many mouse show as as both Mouse and Keyboard.

  • The Keyboard entries can usually be ignore.
  • -m 1 in the grep returns only the first line.
    • This shows that id=8 is the relevant line.
    • This id may change upon system reboot, so for any future scripts using the id, it is best this is calculated beforehand: 
      xinput | grep -m 1 "DeathAdder" | sed 's/^.*id=\([0-9]*\)[ \t].*$/\1/'
    • returns: 
      8

...

NOTE: This is the same as above.

Determine the Device Node

xinput list-props 8 | grep 'Device Node'

returns:

Other way to obtain information

For USB devices: 

lsusb -v | grep -e idProduct -e idVendor

NOTE: lsusb uses /var/lib/usbutils/usb.ids to translate ids to names.

For the IDs only: 

grep . /sys/bus/usb/devices/*/id*

XOrg Configuration

Putting it all together, a new XOrg configuration InputClass Section would look like:

/usr/share/X11/xorg.conf.d/60-razer-deathadder-v2.conf
Section "InputClass"
    Identifier "Razer Deathadder v2"
    MatchDevicePath "/dev/input/event*"
    MatchProduct "Razer Razer DeathAdder V2"
    MatchVendor "Razer"
EndSection
