监听USB设备的插拔，请求USB设备权限，获取当前连接的所有USB设备

• 集成插件步骤请参考https://www.cnblogs.com/wenrisheng/p/18323027

1. 下载demo，拷贝demo里的AndroidManifest.xml文件到uniapp项目根目录下
2. 点击插件页面右上角的"试用"按钮，按照提示集成到uniapp项目
3. 删除本地基座和手机app
4. 重新自定义基座运行

    import {
        UTSUsbManager,
    } from "@/uni_modules/wrs-uts-usbmanager";

• 监听USB设备的插拔

                // 注册USB插拔监听
                UTSUsbManager.registerReceiver(this.action, (resp) => {
                    let action = resp.action;
                    switch (action) {
                        // USB授权结果
                        case this.action: {
                            let granted = resp.granted
                            let action = resp.action
                            let device = resp.device
                            this.showMsg("有USB设备授权结果:" + JSON.stringify(resp));
                            if (granted) {
                                this.showMsg("有USB设备授权成功");
                            } else {
                                this.showMsg("有USB设备授权失败");
                            }
                        }
                        break;
                        // 监测到有USB拔出
                        case "android.hardware.usb.action.USB_DEVICE_DETACHED": {
                            this.showMsg("有USB设备拔出:" + JSON.stringify(resp));
                        }
                        break;
                        // 检测到有USB插入
                        case "android.hardware.usb.action.USB_DEVICE_ATTACHED": {
                            // USB插入时，有些设备会监听到USB插入-USB设备拔出-USB设备插入这么个过程，可能是系统或USB设备的bug
                            this.showMsg("有USB设备插入:" + JSON.stringify(resp));
                        }
                        break;
                        default:
                            break;
                    }
                })

• 取消监听USB设备的插拔

UTSUsbManager.unregisterReceiver()

• 获取当前连接的所有USB设备

        UTSUsbManager.getDeviceList((resp) => {
                        this.showMsg(JSON.stringify(resp))
                        // {"devices":[{"deviceName":"/dev/bus/usb/001/017","interfaceCount":2,"interfaces":[{"id":0,"name":"Espressif CDC Device","interfaceProtocol":0,"interfaceClass":2},{"id":1,"interfaceProtocol":0,"interfaceClass":10}],"deviceId":1017,"deviceProtocol":0}]}
                });

• 请求某个USB设备权限

权限结果在registerReceiver里回调

let device = devices[index];
let deviceId = device.deviceId;
let requestCode = this.requestCode;
let action = this.action;
// FLAG_IMMUTABLE = 67108864
// FLAG_ONE_SHOT = 1073741824
// FLAG_MUTABLE = 33554432
let flags = 67108864;
UTSUsbManager.requestPermission(deviceId, requestCode, action, flags);
