Can't instanciate multiple HID devices #9973

tankyx · 2024-07-01T16:35:00Z

Board

ESP32S3

Device Description

DevkitM1, plain board, both USB ports connected to host

Hardware Configuration

Optical sensor connected to GPIO21, GPIO38, GPIO47, GPIO48, GND and 3v3

Version

latest master (checkout manually)

IDE Name

Arduino IDE 2.3.2

Operating System

Windows 10

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

I am implementing an optical sensor using the USBHID.h library. It works well and I am able to send movements to the host. As soon as I instantiate a Custom HID device, the host won't receive the movements (I don't know if it is the board not sending or the host not receiving).

I tried your exact code, with the exception that I do not have PAW3370, so instead my main sketch looks like:

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  hid.begin();
  USB.begin();
  pinMode(0, INPUT_PULLUP);
}

void loop() {
  static bool btn = digitalRead(0);
  bool btn_now = digitalRead(0);
  if(btn != btn_now){
    btn = btn_now;
    if(!btn_now){
      Mouse16.click(1);
    }
  }
  delay(10);
}

Mouse works fine on my computer and I can see both devices in the USB tool I have. Main difference is that I am on a Mac and have no idea what things look like on Windows. Code looks fine and works fine, except you should not call customHID.receiveReport yourself. That will be called once the host sends data to the device.

tankyx · 2024-07-02T07:04:03Z

Indeed, I tried on both MBP M1 and MBP M3 and it was working without any issues, with both devices showing up. Probably some windows shenanigans happening. Could you please investigate ?

me-no-dev · 2024-07-02T07:31:38Z

I can't. I do not have a windows machine and the colleague that does just went out on a month long leave... One suggestion for you is to set the USB mode in the board menu to TinyUSB (I saw in the logs it was the default USB/JTAG selected)

tankyx · 2024-07-02T09:26:33Z

Yeah I have done that :

USB Mode to USB-OTG (TinyUSB)
Upload mode UART0/Hardware CDC

I dont really understand why Windows is not allowing the Arduino to work as intended

me-no-dev · 2024-07-02T10:34:12Z

Maybe it does not like something in the vendor descriptor? Can you try with a standard TinyUSB one? https://github.com/espressif/arduino-esp32/blob/master/libraries/USB/examples/HIDVendor/HIDVendor.ino

[  1024][D][USBHID.cpp:179] tinyusb_load_enabled_hid_devices():   ID:   6, Type: FEATURE, Size: 63, Usage:   VENDOR

And I can see it being plugged in as a USB Input Device with device type HID (Human Interface Device). Should I use that standard HIDVendor in my code ?

tankyx · 2024-07-02T13:35:56Z

I added the standard HIDVendor device to my code, I still get the issue on Windows. Not on MacOS though

#include "Mouse16.h"
#include "CustomHIDDevice.h"
#include "PAW3370.h"
#include "USBHIDVendor.h"

USBHIDRelativeMouse16 Mouse16;
//USBHIDCustomDevice customHID;
USBHIDVendor Vendor;
PAW3370 sensor;

static void vendorEventCallback(void *arg, esp_event_base_t event_base, int32_t event_id, void *event_data) {
  if (event_base == ARDUINO_USB_HID_VENDOR_EVENTS) {
    arduino_usb_hid_vendor_event_data_t *data = (arduino_usb_hid_vendor_event_data_t *)event_data;
    switch (event_id) {
      case ARDUINO_USB_HID_VENDOR_GET_FEATURE_EVENT: Serial.printf("HID VENDOR GET FEATURE: len:%u\n", data->len); break;
      case ARDUINO_USB_HID_VENDOR_SET_FEATURE_EVENT:
        Serial.printf("HID VENDOR SET FEATURE: len:%u\n", data->len);
        for (uint16_t i = 0; i < data->len; i++) {
          Serial.printf("0x%02X ", *(data->buffer));
        }
        Serial.println();
        break;
      case ARDUINO_USB_HID_VENDOR_OUTPUT_EVENT:
        Serial.printf("HID VENDOR OUTPUT: len:%u\n", data->len);
        for (uint16_t i = 0; i < data->len; i++) {
          Serial.printf("0x%02X ", *(data->buffer));
        }
        break;

      default: break;
    }
  }
}

void setup() {
    Serial.begin(115200);
    SPI.begin(PIN_CLK, PIN_MISO, PIN_MOSI, PIN_CS);

    if (!sensor.init()) {
        Serial.println("Failed to initialize PAW3370");
        while (1);
    }
    Vendor.onEvent(vendorEventCallback);
    Mouse16.begin();
    Vendor.begin();
    USB.begin();
}

void loop() {
    int16_t delta_x, delta_y;

    if (!sensor.read_motion(&delta_x, &delta_y)) {
        Serial.println("Failed to read motion data");
    }

    if (delta_x != 0 || delta_y != 0) {
      Mouse16.move(delta_x, delta_y, 0, 0);
    }

    if (Vendor.available()) {
      Vendor.read();
    }
}

@me-no-dev Couple of updates on the matter :

Uploading the code with both the Mouse and HIDVendor devices on my XIAO Seeedstudio ESP32S3 works on Windows.
Uploading the code with both the Mouse and the CustomHID triggers an error 10 in the device manager and doesn't work.

me-no-dev · 2024-07-10T10:41:20Z

That means that Windows does not like something in your vendor descriptor. I wonder what... what is different from the default one?

tankyx · 2024-07-10T12:53:06Z

I don't really know to be fair. Now I have the custom device showing up, but I can't communicate with it.

This is the definition of my two devices.

Following is my host code :

void MouseController::sendHIDReport(int16_t dx, int16_t dy) {
    HIDReport report;

    std::cout << "Sending HID report: " << dx << " " << dy << std::endl;

    report.reportId = 0x06; // Use HID_REPORT_ID_VENDOR = 0x06
    report.dx = dx;
    report.dy = dy;
    memset(report.padding, 0, sizeof(report.padding));

    DWORD bytesWritten;
    std::cout << "Size of report: " << sizeof(report) << std::endl;
    //BOOL res = WriteFile(hidDevice, &report, sizeof(report), &bytesWritten, NULL);
    BOOL res = HidD_SetOutputReport(hidDevice, &report, sizeof(report));
    if (!res) {
        int err = GetLastError();
        std::cerr << "Failed to send HID report: " << err << std::endl;
        if (err == 995 || err == 1167) {
            std::cerr << "Device disconnected" << std::endl;
            CloseHandle(hidDevice);
            hidDevice = nullptr;
            Sleep(2000); // Wait for device to reconnect
            ConnectToDevice();
        } else {
            exit(1);
        }
    } else {
        std::cout << "HID report sent successfully: " << dx << " " << dy << std::endl;
    }
}

It seems also that my device reboots when it receives too much data for too long

Not sure if this is related, but I do have trouble using CDC and HID simultaneously. After some time, one or the other seems to stall, see #9582 (comment).
