I made a small modification to one of my Red’s. I modified the Raspberry connector, routing the D+/D- signals of the USB_IOT. I need to connect to another microcontroller.
Could anyone provide me a hint about how to activate that connection? I have already tested, but seems that when connecting that USB port to a USB on a linux machine, nothing happens.
I’m unsure if I have to also connect the V_IOT signal, or just leave the VBUS pin unconnected.
Moreover, do I need to further configure the HSIC hub?
Thanks a lot.
