[Pico W] Vendor specific host

Hi evryone, I have three hubs interconnected between them and each hub has an stm32 usb device vendor specific and i want to plug the hubs to the usb of the pico W to send the data through wifi. I'm not expert of usb and i don't find example for vendor specific host in the tinyusb library, can you help me and tell me how can i build the solution ? Thanks

Is this the same question as the one from 8 January?

i'm on the same subject and working on the usb
