Expansion hub

[Ismaclst]

I bought a used expansion hub and I'm having an issue with it. I think it's the connection where the USB plugs in from the relay box. When I plug it in I get no power on the hub. If I wiggle the USB cable where it plugs into the expansion hub, the led power light will flicker. I tried two different USB cable's with the same results.

Looks like it is bad.

Buy some good automotive dielectric grease. Silly to think these connection wouldn't corrode. Intended use and a Salt water aquarium are far apart. Protect your investment.

If pin tension get loose.And it will weather you move connector or not. Micro fretting will result in bad connection i.e.:bus lock.
