RC-N1遥控器不认Pico4的新固件。
Pico 4是一款VR一体机。运行Android 10，可以安装安卓的2D程序或VR程序
编译v4.17的 FPV demo ，在Android手机、Pico3、Pico4的旧固件上，都可以正常运行，可以获取无人机画面。
最近升级了Pico4到最新v5.9固件后，就无法正常连接了。
1.已申请App Key并填入AndroidManifest.xml
2.从Pico 4的画面中可以看到，RC-N1对Pico设备的USB充电每隔8、9秒就会断开，然后重复充电、断开、充电、断开……
3.该Pico 4设备目前的PUI系统固件版本是v5.9.2（该Pico 4设备之前在低版本时也可以正常连接获取无人机画面）。且，我还有一台Pico neo3设备，该设备处于v4.7.x版本，也可以正常连接RC-N1遥控器，可以获取画面。
4.APP运行，在logcat日志中，DJIUsbAccessoryReceiver显示错误信息提示：
getModel: AccessoryChat（正常应为com.dji.logiclink）、
currentModel saved: UNKNOWN（正常应为LOGIC_LINK）、
getManufacturer: PicoStreaming（正常应为DJI）。
5. 对比新旧Pico固件系统进程，发现Pico新固件多了个 com.picoxr.streaming.deviceservice 的系统进程。
