I have one of
Mbeat 7-port multi USB3.0 and USB2.0 hubs. Few people here on IIS recommended it and it has not skipped a beat since I got it.
It is powered (3A power supply) and has 4x USB3.0 and 3x USB2.0 ports. I had no issues running EQ6, guide cam, imaging cam, temperature sensor and a custom dew heater controller (monitoring only, not the straps).
