Hello everyone,
I'm experiencing some difficulties with my setup and would greatly appreciate any insights or solutions you might have. I'm attempting to connect my Phantom 4 remote controller to my Huawei Mediapad M5 tablet, along with an additional USB device.
Here's my setup:
Huawei Mediapad M5 tablet
Phantom 4 remote controller
USB-A to USB-A cable: https://www.amazon.de/dp/B089FBV4DQ?psc=1&ref=ppx_yo2ov_dt_b_product_details
OTG (On-The-Go) adapter: https://www.amazon.de/dp/B07NSQ56J9?psc=1&ref=ppx_yo2ov_dt_b_product_details

I connected the USB-A to USB-A cable from the Phantom 4 remote controller to a USB hub and then connected this USB hub to the OTG adapter. However, when I tried to use the DJI GO 4 App, it didn't recognize the remote controller. Interestingly, any other USB devices I connected to the tablet, such as a USB-Stick, mouse, or keyboard, were detected without any issues.
In an attempt to troubleshoot, I used my smartphone with a USB Type C port and a USB-C hub. I connected the Phantom 4 remote controller to the tablet using the USB-A to USB-A cable. Unfortunately, this configuration didn't work either, even though other USB devices connected to the hub were recognized.
I suspected that the issue might be with the USB-A to USB A-cable. To test this, I used a micro USB to USB-A adapter (Sony EC310) along with the USB-A to USB-A cable to connect the remote controller directly to the tablet. Surprisingly, this configuration worked in approximately only 1 out of 10 attempts.
Connecting the remote controller to the tablet using a standard smartphone data cable (USB-A to micro USB/USB-C) works perfectly fine. I'm aware that the micro USB connector has 5 pins, while the USB-A connector has only 4 pins, with certain applications requiring the connection of the 4th and 5th pins of the micro USB connector. Could the issue be related to the USB-A to USB-A cable I'm using?
Any help or suggestions would be greatly appreciated. Thank you in advance for your assistance!
Best regards,
Patrick
