[Feature] USB Host functionality

[aschueth]

I have a USB peripheral (GPS puck) that I would like to read into an ESP32-S2 board. I naively thought this was going to be simple, but am now realizing it is quite nuanced. From what I understand, using USB_CDC is not realistic since the ESP32 board needs to be USB-host. Additionally, from what I understand, the tinyUSB library (https://github.com/hathach/tinyusb) supports USB-Host, but this library does not. I have been pointed to this library (https://github.com/chegewara/EspTinyUSB) in the meantime for USB-host functionality, but I believe it would be a good fit in this current library as well.

On the topic of this;

I can see the newly added pico PIO usb host and example. I currently have a usb keyboard plugged into a pico.
I've run the example, i get the device descriptors back correctly.

How would i then go about reading keystrokes etc from the keyboard? i cant see anything that would allow this

basic host function with hid and msc is already implemented with rp2040 using pio-usb
