ESP32 USB Soft Host library for Arduino IDE

What is it?

This is mainly a wrapper around the excellent work of Dmitry Samsonov (@sdima1357) with esp32_usb_soft_host

Some parts of the code (e.g. the timer group isr calls) have been regressed to fit esp-idf 3.3 needs.

USB Low Speed is slow

ESP32 USB-LS Soft host (:warning: LS=low speed) is a pure software implementation of USB host thru general IO pins.

Features

The library supports up to 4 HID low speed devices simultaneously. A callback can be attached both for detection and events.

Hardware support

This library has been tested on ESP32-Wroom/Wrover and works fine as long as the pins aren't shared (beware of the psram pins!). It remains untested (but useless) on ESP32-S2, and can't compile (yet?) on ESP32-C3.

Known working HID devices:

  • USB Keyboards: any, but consider powering externally it has backlights and/or other gadgets
  • USB Mice:
    • LogiLink ID0062 (idVendor=0x1a2c, idProduct=0x0042): Data recieves - 10/10 , led fired - 10/10;
    • Microsoft Intellimouse 1.1 (idVendor=0x045e, idProduct=0x0039): Data recieves - 10/10, led fired - 10/10
    • Microsoft Wheel Mouse (idVendor = 0x045e, idProduct = 0x0040): Data recieves - 6/10, led fired - 6/10;
    • ASUS Logitech M-UV55A: Data recieves - 7/10 , led fired (complete init?) - 10/10
    • ASUS (Logitech) Optical USB Black #M-UV55A (idVendor = 0x046d, idProduct = 0xc016): Data recieves - 7/10 , led fired (complete init?) - 10/10;
    • A4Tech SWOP-48 (idVendor = 0x093a. idProduct = 0x2510): Data recieves - 10/10 , led fired - 10/10
    • Genius Netscroll 110X (idVendor = 0x0458, idProduct = 0x003a): Data recieves - 10/10, led fired - 10/10
    • Logitech B100 (idVendor=0x046d, idProduct=0xc077): partial detection, may need several resets before events are fired
    • Logitech M-BT83 (idVendor = 0x046d, idProduct = 0xc03e), Data recieves - 5/10, led fired - 5/10;
    • A4Tech X-7??? , gaming mouse w/o label [ VID_09DA&PID_8090&REV_0606&MI_00 ]. Not recognized by driver, no any info in the Serial Monitor exist.
    • A4Tech OP-720 (idVendor = 0x093a, idProduct = 0x2510): Data recieves - 5/10, led fired - 10/10;
    • Oklick-305m: Data recieves - 0/10 (sic!), led fired - 10/10 (i guess it always turned on, independing of init result )
    • Exegate SH-9018: Data recieves - 0/10, led fired - 10/10. Device reaction looks like Oklick-305m
