I am trying to check if USB Debugging is turned on or off through NPM/Node. As soon as an android phone is connected to my system and USB Debugging is turned off, then i need to show a prompt to user to enable usb debugging on his phone.

According to my research, every device (Scanner/Phones/USB) connected to my system has a unique GUID which helps me to distinguish which device is connected. Further, i'm not able to fetch the usb debugging details. Please help!

Code which i have written so far is on the basis of iSerialNumber but i want to distinguish it on the basis of BUS-TYPE GUID.

var usb = require('usb');
usb.on('attach', function(device) {
var devices = usb.getDeviceList();
var check = devices[0].deviceDescriptor;
if(check.iSerialNumber == '3')
{
    console.log("Please enable USB Debugging");
}
else
{
    console.log("Connect an Android device");
}

});

I'm facing these issues.

if(check.iSerialNumber == '3')

iSerialNumber不是实际的序列号，而只是存储在设备中的序列号字符串描述符的索引。您可以在此链接上查看有关 USB 设备描述符的更多详细信息。USB 设备不使用GUID，但操作系统本身可以使用 GUID，如此处所述。序列号在此处提到的每个非电话 Android 设备中都是唯一的，因此不建议使用序列号将设备标记为 Android。我发现的最好方法是检查设备供应商 ID 和产品 ID，它们分别存储在设备描述符中，分别为idVendor和idProduct。我找到了供应商 ID 列表，但没有找到每个供应商的产品 ID 列表。

Android 设备公开了几个用于不同目的的接口，如 MTP、PTP、Mass Storage 和 USB 调试等。我们想找出具有接口类 255、接口子类 66和接口协议 1的 USB 调试接口的状态。我在这里找到了这些数字。

程序首先测试新连接的设备是否为 Android，如果是 Android，则检查 USB 调试。我不是普通的 node.js 用户，所以我的代码不好。

main.js

var usb = require('usb');
usb.on('attach', function(device) {
    getDeviceInformation(device, function onInfromation(error, information)
    {
        if (error)
        {
            console.log("Unable to get Device information");
            return;
        }

        if (isAndroidDevice(information))
        {
            if (!isDebuggingEnabled(device))
            {
                console.log("Please enable USB Debugging from Developer Options in Phone Settings");
                return;
            }

            //Do your thing here
            console.log("Device connected with Debugging enabled");
            console.log("Device Information");
            console.log(information);
            console.log();
        }
    });
});

function getDeviceInformation(device, callback)
{
    var deviceDescriptor = device.deviceDescriptor;
    var productStringIndex = deviceDescriptor.iProduct;
    var manufacturerStringIndex = deviceDescriptor.iManufacturer;
    var serialNumberIndex = deviceDescriptor.iSerialNumber;

    var callbacks = 3;
    var resultError = false;
    var productString = null;
    var manufacturerString = null;
    var serialNumberString = null;

    device.open();
    device.getStringDescriptor(productStringIndex, function callback(error, data)
    {
        if (error)resultError = true;
        else productString = data;

        if (--callbacks == 0)onFinish();
    });

    device.getStringDescriptor(manufacturerStringIndex, function callback(error, data)
    {
        if (error)resultError = true;
        else manufacturerString = data;

        if (--callbacks == 0)onFinish();
    });

    device.getStringDescriptor(serialNumberIndex, function callback(error, data)
    {
        if (error)resultError = true;
        else serialNumberString = data;

        if (--callbacks == 0)onFinish();
    });

    function onFinish()
    {
        device.close();

        var result = null;
        if (!resultError)
        {
            result = {
                idVendor: deviceDescriptor.idVendor,
                idProduct: deviceDescriptor.idProduct,
                Product: productString,
                Manufacturer: manufacturerString,
                Serial: serialNumberString
            };
        }

        callback(resultError, result);
    }
}

试试这个代码，但它只适用于三星设备：-

var usbDetect = require('usb-detection');
var Promise = require('bluebird');
var adb = require('adbkit');
var client = adb.createClient();

usbDetect.on('add', function(dev) {
    setTimeout(checkAndyDevice, 1500);
 }); 

var checkAndyDevice = function(){
 client.listDevices()
      .then(function(devices) {
        return Promise.map(devices, function() {
          return devices;
        })
      })
      .then(function(id) {
        if((JSON.stringify(id)) == '[]')
        {
            console.log("Please enable Usb Debugging option from your Android device");
        }
      })
      .catch(function(err) {
        console.error('Something went wrong:', err.stack)
      });
 };
