An Arduino wrapper to @sdima1357's usb_soft_host esp-idf example

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 but it has been tested up to 4.4.2.

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 has partial support for ESP32-S2, and remains untested on ESP32-S3 && 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

esp32-usb-soft-host's Issues

scan codes

This lib is perfect, I just don´t know how to decode the data received to scan code.

Can you help me?

Has anyone tested its latency?

I'm trying to make a low cost keyboard latency tester, wondering if ESP32 can do it, but I have no logic analyzer.

mouse example

Hi, Can you provide an example on how i can catch data from a connected mouse?
the mouse gets detected, but nothing more then that. if I plug in a keyboard i at least get raw data

Sending Print data to Thermal printer controlled by ESP32 via HID .

Dear sir,
My device is a thermal printer with an ESP32 controller. In that case, I have to send the print data from a 3rd party exe to my printer via the HID port. As per your tested H/W devices, the library is compatible with certain mice and keyboards. Is there any support for printers, mainly 3/2-inch thermal printers? 
Any help would be great.

Regards,
Vineeth B

@suarezvictor your fork is very impressive and I wish I found it earlier.

Before starting to integrate your changes, I need to establish an exhaustive board list to handle to the workflow matrix that will run the build tests. Did I miss any device?

SNES Controller not detected

This is a bit weird issue.
I spent some time developing a USB to DB9 (Commodore 64) controller using a SNES game pad.
Everything worked well and because of the 2 Commodore 64 ports I decided to buy a second SNES controller, but this second is not even detected.
Of course I thought that it could have been broken, but tested on a Mac it works perfectly. So I decided to open and inside the two controllers seems quite different. In particular the main difference that I can see is that one controller seems to have a crystal and the other not, but I can't see the chip used because it is under a black cap.

I am a bit stuck here because no message, appears on the console so it seems that the device is not detected in any way.
Is there something that I can do to debug this issue?

ADB device host emulation ? (single purpose of setting adb tcpip enable)

Hello
I have a very pointed use case for this that might be useful to really a LOT of people.

And it is the ESP32 behaving as an ADB host to execute only one specfic command

"adb tcpip 5555"

You see, most modern phones are bootloader lock and unrootable.
It is impossible to execute any code as root unless you are the manufacturer, network provider or google

This is fine for most people but there is one thing that really unlocks a lot of capability from an android phone and it is enable tcpip network function of the adb client inside the phone.

This is a root function, however, if usb debug mode is enabled (unprivileged user can do it) then it is possible for a adb host device to tell the adb client over usb to enable network capability with the command "adb tcpip 5555" with that number being the port it will listen to for commands

The major problem is that this network connectivity will shut itself off on every reboot.
Currently this requires the user taking the phone back to a real computer running windows or linux to re-enable network connectivity.

So, I would like to inquire, what would it take for the ESP32 to perform this adb host task using software host USB ?

My understanding of the ADB is that is similar to a usb serial port but can be a lot faster.
Upon connection, there is a key exchange, the host provides a key fingerprint and the android client devices shows the user the choice to accept this fingerprint

Then the host would sent the command "adb tcpip 5555" (or another port number) and that would be it.

I can sniff this exchange with my oscilloscope to help developpement of this capability

This would allow anyone with a prepared ESP32 to go to a phone, plug it in the charge port and re-enable network functionality

Example use case
I use two dozen phones as cameras, but unfortunately, the camera will sometime crash when used in viewfinder mode for too long.
The cameras are rigged, pointed to specific locations and I would really prefer not to touch them once they are setup. However sometimes I have to reset them. With an esp32, I could leave it connected at all time (currently, it's just a charge cable) and it would continually query the device (is your port 5555 responding to connections) and if not it would do the sequence of enabling network connectivity

I need this remote connectivity to stop and start all those camera's recording remotely as well as swap camera settings (pushing xml config files)

I believe that many people are in my situation as well. Perhaps it would work to create a payment pool for this feature, I certainly would put my 100$ on that !

Connections made before powering cause error invalid header

I'm having an issue in which a device that is connected to the circuit prior to booting the board will cause the below to repeatedly print. The problem is resolved by unplugging the USB peripheral and plugging it back in while the program is running. Has anyone else had this issue come up?

My project is for an embedded device so I'll be unable to just unplug and plug in the USB device.

Serial USB adapter?

It is possible to connect a USB serial adapter like FTDI or CH340? I'm thinking of using this as a 3d printer server using USB and not the serial interface. Like a octoprint server.

CapsLock Problem

It's exciting when the lcd appeared what i type by keyboard, but then i found a problem about CapsLock. I could change CapsLock state only once. Through some debug, i solved this problem. Now i can change CapsLock state just as i wish.
Origin Code(usbkbd.h):

virtual uint8_t HandleLockingKeys(uint8_t key)
    {
      switch(key) {
        case UHS_HID_BOOT_KEY_NUM_LOCK:
          bmNumLock = ~bmNumLock;
        break;
        case UHS_HID_BOOT_KEY_CAPS_LOCK:
          bmCapsLock = ~bmCapsLock;
          //Serial.printf("CapsLock Changed.CapsLock:%d\n",bmCapsLock);
        break;
        case UHS_HID_BOOT_KEY_SCROLL_LOCK:
          bmScrollLock = ~bmScrollLock;
        break;
      }
      return 0;
    };

Modified Code:

 virtual uint8_t HandleLockingKeys(uint8_t key)
    {
      switch(key) {
        case UHS_HID_BOOT_KEY_NUM_LOCK:
          bmNumLock = !bmNumLock;
        break;
        case UHS_HID_BOOT_KEY_CAPS_LOCK:
          bmCapsLock = !bmCapsLock;
          //Serial.printf("CapsLock Changed.CapsLock:%d\n",bmCapsLock);
        break;
        case UHS_HID_BOOT_KEY_SCROLL_LOCK:
          bmScrollLock = !bmScrollLock;
        break;
      }
      return 0;
    };

Just change a operator from ~ to !.

Don't work USB_Test program

Hello,

We're testing with a keyboard connected to the ESP32-DevKit C-32E.
But when I type on the keyboard, I don't see the keys.
GPIO has DP connected to 16 and DM connected to 17, with the other pins disabled.
Do you have any advice?

support for wireless keyboards?

the library successfully worked for wired keyboards but can we make it work out for wireless keyboards as well? i'm using logitech mk215 wireless keyboard and it's not working.

add support to read and print keystrokes.

hello, it would be more helpful if you can add support for usb keyboard to read and serial print the keystroke.

Connection issue

Hello.

I want to ask for schematic.

Do you put +5V on USB connector, and connect D+/D- directly to ESP32 pis (without voltage level shifter)?

I have tried connect some devices to ESP32 thru cheap 5V<->3.3V level shifter and have no success. Keyboard and one mouse with long cable (~1.4m) is not recognized, and another mouse with shorter cable (~0.8m) is unstable recognized .

Unfortunately i'm not sure about ESP32's pins 5V toolerance and i affraid to burn out microcontroller.

Thanks for your time.

Crashes when using Bluetooth

Base on the example here, I added ESP32 BLE Keyboard library to it.

#include <BleKeyboard.h>
BleKeyboard bleKeyboard;

void setup()
{
  //...
  Serial.println("Starting BLE work!");
  bleKeyboard.begin();
  return;
}

I found that it crashes at whatever execute later, bleKeyboard.begin() or USH.init().

The ESP32 I am using is ESP32-DevkitC (ESP32­WROOM­32D).

ble.begin() before USH.init()

Won't compile

I couldn't get the example code to compile without removing all the "inline" tags (on the function declarations). Do these serve a purpose that will cause problems later down the road, or are they safe to remove?

Support for esp8266?

Does the library supports esp8266/NodeMCU?

Can I connect to a serial device

Can I connect to a device that exposes serial over USB?

ESP32-CAM Does not detect any USB device being attached

I couldn't get "New device detected on USB" at all. I have an ESP32-CAM. Here's the pinout: https://i0.wp.com/randomnerdtutorials.com/wp-content/uploads/2020/03/ESP32-CAM-pinout-new.png?quality=100&strip=all&ssl=1

I have tried with multiple PIN configurations and only for DP_P0 and DM_P0 which I believe means Data Plus USB0 and Data Minus USB0. Last one I tried is 13 and 12.

I had a USB extension cable and removed data pins (green and white) coming from female (host) part and connected to GPIO pins of the board. Power cables (red and black) is connected normally so I can power the device via a USB port.

What am I doing wrong? Do I need to share the power or at least ground between them or something?

Can it forward the data somehow?

This may be a duplicate question. I am trying to identify from your git repo if it is possible to read the usb device details(which it does) and then also forward the data as it is to computer?
i.e.: I connect a mouse to esp32(via usb) and then get the data coming from the mouse in esp and forward it serially to let's say my computer? or why not forward the data to computer via mqtt!?

So in one line the question is "Can it send and receive the data from and to the usb device connected??"

cpu freqency promble

The board that i used is ESP32 DEVKIT V1,when i set the cpu frequency 80MHz,USB Test failed. I wasted several hours to find problems, finally i tried to change cpu_freq, 240MHz and 160MHz were successfully ! But I when was trying 80MHz again, it failed. I don't konw it is just only my problem or there is a request to set cpu_freq bigger.

Not an Issue: Possible to add support to send data?

Hi,

I appreciate this isn't an issue, but just wondering if it's possible to add support to send data?

I have a universal HID device I created that I'd like to talk to via USB Soft Host, would it be difficult to implement?

how import freertos ?

Are Wemos Lolin ESP32-S3 with integrated USB-OTG connector compatible ?

Hi,
I'm a fairly beginner in the esp scene but I have a project to use a old Razer Nostromo Keypad as a "programmable macro keypad"

But first I want to try with a dumb spare keyboard I have

I have some Wemos LOLIN ESP32-S3 (+mini) ( => https://www.wemos.cc/en/latest/s3/s3.html )
at hand and wanted to use the integrated USB-OTG port to plug my keyboard in it...but it doesn't seem to work

From the wemos datasheet D+/D- are on GPIO19/20 but they do not appear on the board itself, are the 19/20 pin internally linked to USB-OTG...idk

Or do I have to use an USB breakout ? But what about the 19/20 pins for D+/D- then ?
Is the USB-OTG connector even usable as host for that purpose ?

I'm new to this so if someone could help me understand what's going on...I've seen other S3 devkit with 19/20 pins (D+/D-) + jumper on the back with USB-OTG label like this one : https://fr.aliexpress.com/item/1005004637451669.html?spm=a2g0o.productlist.main.7.1bb4lrB5lrB5VG&algo_pvid=72f72592-110c-4d9f-9796-a3915fba881f&algo_exp_id=72f72592-110c-4d9f-9796-a3915fba881f-3&pdp_npi=4%40dis%21EUR%213.50%213.50%21%21%213.71%213.71%21%402103847817090586028926195ed234%2112000036725496197%21sea%21FR%214009116193%21&curPageLogUid=sZIBwRg1ozyj&utparam-url=scene%3Asearch%7Cquery_from%3A

Videos of attached keyboard projects I found :
https://www.youtube.com/watch?v=WPlPRkPx1_8
https://www.youtube.com/watch?v=gg58sClHjIg

Is it possible to translate the device to another?

to keep it simple, let's say i have a mouse but i won't to fool my computer into thinking it as a keyboard(sorry for a lame example), is that possible??

The real world application can be, sometimes we don't have the exact device on the place to test. We can get the device's usb info, duplicate it and use or the test the software temporarily!!

Is this possible somehow?!
