Raspberry Pi OS • Re: Missing hidg0 for keyboard emulation on pi 400

I've not tried the USB HID gadget on RPiOS Bookworm.

On Bullseye and earlier /dev/hidg0 appears automatically once the gadget has been configured.

I usually do that as follows:

1. Add the following to config.txt

   Code:

   dtoverlay=dwc2

2. Make sure the following is not present in config.txt or if it is present make sure it is commented out

   Code:

   otg_mode=1

   If present and not commented out (or not inside an inactive conditional filter) this always takes precedence over loading the dwc2 overlay.
3. Run a shell script like this one from /etc/rc.local. Or cron, or a systemd service.
