Pico Pi USB Host audio

[paulhamsh]

Hi
I really want to use a Pico Pi (rp2040) with USB Host audio - TinyUSB doesn't do that, and it looks like CherryUSB does - very exciting and amazing!
I couldn't see a demo for USB Host audio for any boards - is there one, and if not, where do I start on getting it to work with the Pico Pi?
Thanks

If the hcd port with iso transfer is supported, host audio can use, so only ehci and dwc2 have supported iso transfer now. RP2040 has not implemented hcd port.

If you have free time and ability to implement rp2040hcd port, maybe you can use all the classes.

Ah ok - I don't have the ability to do that. I thought it was done already.

My friend will support for this, need sometime.
