出力は次のようcat /proc/bus/input/devices | grep -i "Mouse\|Touchpad"になります。
N: Name="ELAN1300:00 04F3:3087 Mouse"
H: Handlers=mouse0 event5
N: Name="ELAN1300:00 04F3:3087 Touchpad"
H: Handlers=mouse1 event6 `
の出力はxinput list | grep -i "Mouse\|Touchpad"次のようになります。
⎜ ↳ ELAN1300:00 04F3:3087 Mouse id=13 [slave pointer (2)]
⎜ ↳ ELAN1300:00 04F3:3087 Touchpad id=14 [slave pointer (2)]
