any ideas on wether or not
this hub would allow over clocking beyond 50 osc6 bits if they were plugged into he 1.2 A ports?
The 1.2A ports only work, if no computer is connected! On the page you will find a footnote:
2 Enter the Fast-Charge Mode by disconnecting the DUB-H7 from your computer, or by powering off your computer. It is recommended that the total power consumption of
the connected USB devices should not exceed 2.4 A, or 12 W.
I would recommend an USB3 Hub. USB3 allows up to 900mA per port.
