Yes you are right, the 80% of issues are always power related.
Yours may not be a problem with the hub but a problem with the power source of the hub. You have to be sure the power source is providing the amps required.
I have a full equipped OpenPlotter (weather sensors, IMU, 1W sensors, switches, outputs, DVB-T, GPS dongle, NMEA 0183-USB, NMEA N2K, WiFi dongle + wifi built-in) connected to the same power source 5V 3A. Both Raspberry 3 and hub are connected to it. The system works right. Sometimes I can see the annoying, multicolour, little square upper right on the screen but performance is not affected.
