VOXL 2 Ethernet Expansion and HUB Power issue

[Jskim]

This is a question about VOXl2 Ethernet Expansion and HUB.

[Model Information]
-system-image: 1.8.02-M0054-14.1a-perf
-hw platform: M0054
-voxl-suite: 1.4.2~beta2

VOXL2 alone works fine and works well when connected to a 5G modem.

[Questions]

1. When using Ethernet Expansion and HUB, it does not work.
   Sometimes it works and sometimes it does not work. It almost never works.
   Once it works, there is no problem even after rebooting,
   but after a day, the same symptom occurs.

In my opinion, the reason it does not work is because VOXL2 power is insufficient.

2. Please tell me the +, - pinmap for the power supplied in the photo.
   I plan to test if it works well when supplying 5V power.
   

If there is a good solution, please let me know.

Thanks,
JS, Kim

Hello, @Jskim

I coundn´t check on the documentation either. But I believe if you use a multimeter in continuity mode and test each pin to a ground plane, e.g., USB shield, you will be able to discover the negative pin. Therefore, the positive is the other one.
