Peter Marcisovsky d786f187e9 feat(us/host): set device cfg during enumeration
- user callback funciton to set device configuration
      as a part of usb_host_install
    - callback provides device descriptor of a device being enumerated
    - user can set which cfg descriptor the USB device will be set with
    - user can filter device enumeration
    - Kconfig menu to enable callback function
    - usb_host_lib example demonstration

USB-OTG Examples

See the README.md file in the upper level examples directory for more information about examples.

Common Pin Assignments

Pin assignment is only needed for ESP chips that have an USB-OTG peripheral. If your board doesn't have a USB connector connected to the USB-OTG dedicated GPIOs, you may have to DIY a cable and connect D+ and D- to the pins listed below.

ESP BOARD          USB CONNECTOR (type A)
                          --
                         | || VCC
[USBPHY_DM_NUM]  ------> | || D-
[USBPHY_DP_NUM]  ------> | || D+
                         | || GND
                          --

Refer to soc/usb_pins.h to find the real GPIO number of USBPHY_DP_NUM and USBPHY_DM_NUM.
