History
Tomas Rezucha 2b5caf34b7 tinyusb: Do not access string descriptor array out of boundaries 
The previous version of esp_tinyusb (v1.0.0) always assumed 8 string descriptors.
In case the user passed a smaller array of descriptors,
esp_tinyusb accessed memory outside of the array.
This is fixed esp_tinyusb v1.1.0 by 046cc4b02f

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.
