I don’t think a USB hub is supposed to feed power out of the male connector.
@seven1m indeed it is, as usb is supposed to also deliver power, hoever since usb can also be chained you probably can't power all the devices from a single usb port (unless you want to fry it), hence the psu :)
@manu No, I'm saying it is sending power to the SOURCE. I understand it should power the female ports. But when I plug this into my Mac, the mac shuts down my laptop USB port.
