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?!

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?

Feeling kinda dumb, but I'm getting this error trying to compile the usb_test.ino. There is no such file in this library, but the "usb_host.c" is referencing it. What am I missing? This is the exact error message: "/home/user/Arduino/libraries/ESP32-USB-Soft-Host-main/src/usb_host.c:18:25: fatal error: hal/cpu_hal.h: No such file or directory compilation terminated."

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.

small conversion problem

instead config.auto_reload = 1 better config.auto_reload = (timer_autoreload_t) 1;

suggestion: https://github.com/tobozo/ESP32-USB-Soft-Host/pull/2

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??"

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.

Copy paste problem :)

instead of printCB( pcurrent->Resp0, pcurrent->R0Bytes ); must be: printCB( pcurrent->Resp1, pcurrent->R1Bytes );

Descfription: In Resp0 response from ep0 (end point 0) In Resp1 response from ep1 (end point 1) Several HID devices have 2 end points . For example - combined mouse keyboard device

The Lib works fine with an apple mouse (desc.idVendor = 0x05acdesc.idProduct = 0x0304). I need to connect a USB QuickScan. Any idea? Any other usb scanner? Thankyou

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?

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()

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?
