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。

———————————Logcat查看日志觉得奇怪的部分———————————————

1. USB连接反复断开

DJIUsbAccessoryReceiver E receive action: android.hardware.usb.action.USB_STATE

——————————————————————————————————————————

2. DJIUsbAccessoryReceiver 显示设备名称“不匹配”

DJIUsbAccessoryReceiver E getModel: AccessoryChat

DJIUsbAccessoryReceiver E currentModel saved: UNKNOWN

DJIUsbAccessoryReceiver E getManufacturer: PicoStreaming
ConnectDebug I (1711814259169) DJIUsbAccessoryReceiver getManufacturer: PicoStreaming
DJIUsbAccessoryReceiver E 不匹配
ConnectDebug I (1711814259169) DJIUsbAccessoryReceiver 不匹配

    我瞎猜啊：会不会是RC-N1与 Pico 4 间建立联机时，遥控器检查设备类型，发现不认识的设备（比如说Pico 4新固件把型号改了什么的），遥控器一看不对劲，就主动断开了USB连接

    从您描述的“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……”来看，这似乎是一个遥控器引起的问题，SDK不一定可以解决。相同的问题是否也会出现在DJI Fly上呢？
