Locate the id of multiple input devices and change the value of its property

Question

I was looking at this which answers if there is only one of the device names. The id's can change when unplugging the device and plugging it back in, this is why I need to get them by their names. I however have two:

SteelSeries Sensei Raw Gaming Mouse

How would I fix this in a script? I need the first one to have specific settings and the second one to have specific settings.

In other words how do I acquire both id's and in the order they appear? Some sort of for loop that checks the output or something.

Run xinput | grep "id=12" to get the first one, and xinput | grep "id=14" to get the second one, assuming that those id's don't change. — Daniel, Sep 18 '15 at 16:45
@Daniel If you follow the link to the other question you shall see it states that the id may change. — Karl Morrison, Sep 18 '15 at 16:45
Are there indeed 2 different devices or is one a wifi-adapter? — Ron, Sep 18 '15 at 16:59
@Ron My mouse a sensei raw has a button which switches settings for the mouse (hence the two SteelSeries Sensei Raw Gaming Mouse pointers). Nothing to do with WiFi. It's a wired gaming mouse (not wireless). — Karl Morrison, Sep 18 '15 at 17:12

Someone in SO has provided a nice script that might help you. Change the commands accordingly.

You can do something like the following:

if [ "$SEARCH" = "" ]; then 
    exit 1
fi
ids=$(xinput --list | awk -v search="$SEARCH" 

    '$0 ~ search {match($0, /id=[0-9]+/);

                  if (RSTART) 

                    print substr($0, RSTART+3, RLENGTH-3)

                 }'

     )
for i in $ids
do
    xinput set-prop $i 'Device Accel Profile' -1
    xinput set-prop $i 'Device Accel Constant Deceleration' 2.5
    xinput set-prop $i 'Device Accel Velocity Scaling' 1.0
done

So with this you first find all the IDs which match the search pattern $SEARCH and store them in $ids. Then you loop over the IDs and execute the three xinput commands.

You should make sure that $SEARCH does not match to much, since this could result in undesired behavior.

Very nice, will try it. – Karl Morrison Sep 18 '15 at 18:10 — Karl Morrison, Sep 18 '15 at 18:10
