USB Hub not working on 12v
I have an Anker 3+7 port hub (three charging ports, seven device ports). It comes with a 12v 5a power brick and I'm trying to run it off of 12v instead of using the brick. I've run a new 12v line and confirmed proper polarity of the tip, but the hub will not power on with it. Voltage is identical to what the power brick is providing. Is the hub 'confirming' that I am not using the OEM's brick? I would think the fuse would blow if it tried to draw too much power, but the line is still providing power.
