Cant get Ras Pi Zero in usb gadget mode on Trixie to show up in Win10 Device Manager as USB Composite or any other device
My goal is to replace a missing usb device that receives data from a PC thru USB and responds back with a heartbeat on a proprietary protocol.
The game will not play without this specific USB named device from a vendor ID, product ID & desc etc of exact message.
I have successfully flashed a 16GB MicroSD with the latest Raspberry Pi Imager & am able to PuTTy in Windows using WiFi and the user/pw i setup to modify the following once its been updated to Trixie:
I followed various blogs and got the usb gadget service running but Windows never detects a new device only powers it -
I am using the non pwr usb c port closest to the middle which is the data cable direclty to the pc.![:?:]( "Question")
1. modify the last line of config.txt in boot/firmware/ to have dtoverlay=dwc2
2. modify cmdline.txt in boot/firmware at the end to contain:3. Create the Gadget Script Service:The Service is running fine without errors per AND 4. Setup the Service & Register it to start at bootup - once its booted I login via PuTTy ssh and can see the serivce works as expected but nothing shows up on the windows machine:
My goal is to mimic this usb displays protocol once i get this figured out so im wondering if this device can even be setup to received USB commands from a computer & parse the payload and respond with necessary data as well as send a heartbeat packet message back every minute
