使用 NPM/Node 检查安卓手机上的 USB 调试

Question

我正在尝试检查USB调试是否通过NPM/Node打开或关闭。一旦Android手机连接到我的系统并且USB调试关闭，那么我需要向用户显示提示以在他的手机上启用USB调试。

根据我的研究，连接到我的系统的每台设备(扫描仪/电话/USB(都有一个唯一的 GUID，可帮助我区分连接的设备。此外，我无法获取USB调试详细信息。 请帮忙！

到目前为止，我编写的代码是基于iSerialNumber的，但我想在总线类型GUID的基础上区分它。

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");
}

}(;

我正面临这些问题。

Answer 1

if(check.iSerialNumber == '3')

i序列号不是实际的序列号，但它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。GUID不由 USB 设备使用，但可以由操作系统本身使用，如此处所述。如本文所述，序列号在每个非电话 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。我发现的最好的方法是检查设备供应商 ID 和产品 ID，它们分别作为idVendor和idProduct存储在设备描述符中。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设备公开了多个用于不同目的的接口，如MTP，PTP，大容量存储和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是Android，如果是Android，则检查USB调试。我不是常规节点.js用户，所以我的代码不好。

Answer 2

尝试以下代码，但它仅适用于三星设备：-

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)
});
};
