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.

Only the salient id is needed.

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
```
