good idea but no results

never mind strace just wasn't installed

and after following your advice the solution was

setfacl -m u:x321x321:rw /dev/input/*
setfacl -m u:username:rw /dev/bus/usb/001/005

I think it would be better if you add your user to the group input:
adduser your_user input


Then logoff and login again to make efective that change, so then your user will be in the group input hence your user wil have access to those devices.

The proper way would be to create a udev rule to grant permission to your user only as required.
