Did you USB hub have its own external power supply ? If it did not then you
have discovered your problem. If the hub is not using an external supply
then ALL its power is coming from the one USB port and being divided among
the ports in use. In your case you need two powered ports and with the USB
hub are getting only power from one.
(Hubs destined for use with desktops usually include a power plug wart
thing, those destined for laptops often don't have a provision for external
power.)
You can get information on power available and used on USB hubs from
device manager
Universal Serial bus controllers
the various USB Root Hub entries
