USB device configuration
ESP32x SoCs have: a bidirectional control endpoint EP0 IN and EP0 OUT six additional endpoints EP1 .. EP6 that can be configured as IN our OUT a maximum of five IN endpoints concurrently active at any time (including EP0 IN) all OUT endpoints share a single RX FIFO each IN endpoint has a dedicated TX FIFO To avoid a lot of special case handling, the maximum number of IN an OUT endpoints including the control endpoint EP0 is 5.
