Vendor specific host implementation

[maaamcube]

Hello,

I have three interconnected hubs and on each hub I have connected an STM32 whose USB is in vendor-specific device mode. I want to plug it to a pico w to establish wifi communication through usb.

Is there an example on vendor specific host implementation ?

Thanks.
