@tacticaltoast I need to take a look into Manjaro - I have not tested the driver with it before. I am sure that the PowerBlock will also work with it. Probably switching the driver to systemd will solve it (comparable to how the ControlBlock driver is installed, https://github.com/petrockblog/ControlBlockService2/blob/master/scripts/insertLine.sh#L15).

I will come back here soon!

Some how my usb pen drive was corrupted. Uninstaled retropie and did reinstalation process all over again. Must have unpluged pen drive before light stoped blinking so the transfer files with directories not working properly. Everything working properly now.
