It has a 3.3V power supply.
There was a bulged Teapo 1000uF 10V and 1 22uF 50V Teapo that had a little higher esr than normal. I replaced them with 22uF 50V Rubycon YXF and 1500uF 6.3V Nippon-Chemicon KZE (this is the closest grade cap I had in stock).
The power supply is working, but when it is connected with the controller board it refuses to start. The same happens with any computer power supply that I connected. They act like shorted.
So there must be a problem with the hub controller... Is it fixable? Looking it I can't see many parts that can be tested with a multimeter and changed if they are found bad....
