Autostart UsbGps Service

Hello. I’m sorry for my bad english. I have installed the UsbGps Version v2.2.1 (199) application on the car radio. The radio tape recorder has a modified firmware, so there are no requests for access to the USB. I have been trying to configure the service startup for 5 days, but it does not work. The service does not start when the receiver is turned on. Each time you need to go into the application and start manually. I did this, put the script in the “system”-“etc”-“int.d” folder, but it does not start. What am I doing wrong?
