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.

I really need this stuff, can you help me how can i search to build by myself at least ?

i can read those usb's but could not able to communicate through end points

It is enumerated through vid and pid or kind of ? I think the communcation with ep is the complicated part for me also cause i don't have the documentation of that USB.

it shows all the vid pid and all the interfaces and end points but when im trying to communicate through end points i need to provide class drives like which one to use there im stuck .i need to write my own driver i think.

Yes, it is enumerated. I think also you have to write your own vendor if you have already the doc, it can help you much more, they not gonna write every vendor specific for every USB.

i have done this in esp32 s3 using class driver example and talk through end points but here in pico w i have no idea what to do.https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/usb_host_lib

I tried this one also, it's enumerate the USB's with limitation(cause of the number of ep supported by the s3) but i can't talk to it.
Do you have a discord to talk their ?
