I've been "exploring" the FX3 with the superspeed explorer kit. Pretty sweet so far, but I can't for the life of me figure out how to get it to run in a raw packet mode. AKA I simply want a mode where it forwards link layer packets that don't have errors to RAM independent of their endpoints/etc.

Any hints if this is possible, or how to achieve it?

Of course I would like the opposite as well, a way to send a user defined packet back out on the superspeed bus.

Can you please explain more in detail about "raw packet mode" that you are referring?

What I would like is full visibility into the protocol layer. In other words I would like to see the raw notificaitons/transactions/data packets/etc inbound to the device. Sort of a "Trace" mode if you will, between the USB link and protocol layers in the USB stack.

Ideally, I would also like to inject packets at this level, to provide some additional host control functionality beyond what is available with the built in USB2 OTG host controller....
