java端的HashMap<String, UsbDevice>类型怎么转换成对应前端类型

            //---2.逻辑处理  
    const manager = context.getSystemService(  
        Context.USB_SERVICE  
    ) as UsbManager;  
    //取得USB接口信息  
    var deviceList = manager.getDeviceList();  

我通过以上代码获取USB信息，deviceList 结果如下，现在是我怎么把这个结果转换成前端可用的对象，比如我要取mName属性怎么获取

{/dev/bus/usb/005/004=UsbDevice[mName=/dev/bus/usb/005/004,mVendorId=26728,mProductId=1280,mClass=0,mSubclass=0,mProtocol=0,mManufacturerName=Gprinter,mProductName=GP-80,mVersion=4.00,mSerialNumberReader=android.hardware.usb.IUsbSerialReader$Stub$Proxy@6630830, mHasAudioPlayback=false, mHasAudioCapture=false, mHasMidi=false, mHasVideoCapture=false, mHasVideoPlayback=false, mConfigurations=[
