Thanks for reply. But USB3.0 AIO-3399J OTG port didn't work also.

Below is the step I tried:

If PC do not recognize the board , just install Install "RK USB Driver" .
1. Keep power on
2 .Keep dual male usb3.0 data cable connected with host PC
3. Press and hold RECOVERY key, short time press the reset for restart the power.
4. After around two seconds, release RECOVERY key
Then PC will catch the usb device.

Thank you Could you help a bit more?

I made sure the driver installed but still can't catch ...

Might be the win10 problem.
Change another system and try.

Follow the log , it seems it is your cable or connecting problem.
If success , it is impossible go into recovery mode.
