Are you using an FUSB302 with an FUSB340 (USB Switch)? My understanding is that the FUSB302 only provides USB C power delivery along with a USB2.0/USB 3.0 connection. That chip doesn't do anything to allow host and device on the same port. As far as I know that's a function of the SAMA5D27 and the NuttX drivers. I actually don't know if the SAMA5D2 UDPHS and UHPHS can function simultaneously, or whether NuttX supports that. Did you get that working? Or is that the problem you are trying to solve?
So what's the problem with filing a bug? And didn't you add support for the FUSB302 into NuttX? Anyway... we can talk on email for now. Do you have one that doesn't work? I'd love it if you can send it to me. What I got working was CDC/ACM console and CDC/ECM ethernet over USB on the same USB connection. Is that relevant to what you're looking for? If so I can come up with a config that will do that. -adam On Wed, Aug 16, 2023 at 12:47 PM Tim Hardisty <t...@jti.uk.com> wrote: > Hi Adam, > > My board is pushing many boundaries as it allows usb host and device to > coexist on a single physical port using an FUSB302 controller.
