Is your feature request related to a problem?

keyboard-input e.g. for passwords or communication without Serial connection to a PC

Describe the solution you'd like

please make ESP32 able to read user input from USB or BT HID keyboard (standard C/C++ libs, e.g. scanf(), gets(), std::cin ). if BT then first pairing function like usual for BT, if USB then via USB-host at least for standard wired USB-HID-keyboards and possibly also for USB wireless keyboards (e.g., Logitech, Rii) via a USB plug with transmitter. After plugin/pairing the keyboard-input detection should work via plug+play and out of the box with C/C++ stdio.h or std:cin libs like commonly known for Windows/Linux-PCs or SoCs (e.g., RaspberryPi).

Describe alternatives you've considered

if no on-board solution possible please provide an external shield or add-on board for those features

Additional context

N/A

I have checked existing list of Feature requests and the Contribution Guide

  1. This requires HID HOST, which is not implemented in Arduino
  2. We provide Arduino APIs here. For such "standard" APIs, you need to look into ESP-IDF or Crosstool-NG
  3. What you ask for is more application level than Arduino core.

as to "1. This requires HID HOST, which is not implemented in Arduino": then the request is about to implement it to Arduino, IDF is no option (finally this was posted here to the arduino-esp32 repo).
