USB full-speed hub with the P2
Since the P2 can emulate a host and a device, I wonder if it is not possible to create a hub by adding one and one. It wouldn't be anything new, but the application would prove the P2 capabilities. Since I can't program this, I'll leave the challenge to whoever is able to.
Also, I'm thinking about using the P2 in very high impedance mode to sniff USB 3.0 lines for LFPS, but I will probably get in muddy terrain (yes, keeping impedances controlled is a must, and USB doesn't like stubs, or pins sticking out).
