I have a
Raspberry Pi 3 (
Model B) that I would like to act as a USB gadget or OTG peripheral. Some sources state (without proof) that the
USB_ID line is not connected properly, to allow any software hacks to enable OTG behavior.
- I would like to to see the schematics proving this.
- Since there are 4 USB ports on the RP3B it might be possible to make a hardware hack to allow untying one of the ports and use it for OTG.
- Perhaps it's possible to use USB OTG over GPIO?
The only answer touching this subject was this, but is both outdated and doesn't mention any specific model.
