Rock 4 SE OTG/USB_Gadget Not Working

Take latest release of Debian for SE from here :
Flash successfully with balenaEtcher.

Configure USB Gadget:
echo “dtoverlay=dwc2” | sudo tee -a /boot/config.txt
echo “dwc2” | sudo tee -a /etc/modules
echo “libcomposite” | sudo tee -a /etc/modules
sudo touch /usr/bin/usb
sudo chmod +x /usr/bin/usb

Open /etc/rc.local and add a call to ./usr/bin/usb before the script executes the command “exit 0”.

Specify functionality in /usr/bin/usb file

/dev/hidg* is not present

Edit: I have ordered a USB-A to USB-A cable, as I understand USB-A to USB-C doesn’t work properly.

Update: USB-A to USB-A cable does not resolve the issue.

I have been able to enable OTG and set a device descriptor (despite not yet working) by loading dwc3 instead of dwc2.

I changed USB plug and my device descriptor started to be polled correctly. Also, USB-A to USB-C cable works fine.
