Capacitative USB touch not working properly on 7' HDMI IPS (1024*600) Waveshare clone display

Some steps forward:

I used the bash script in this post and calling

bash usb_replug.sh usb1

fixes the issue.

Then i also tried to replace the following line from @oscaracena 's answer

ExecStart=/bin/bash -c ‘while ! $(xset q > /dev/null 2>&1); do sleep 2; done; sleep 5; xinput enable seeed-tp’

with

ExecStart=/bin/bash -c ‘usb_replug.sh usb1’

but it does not work.
What would be the correct way to adapt that answer to this case?
