Using USB hub

I have three external drives I’d like to use with the Live Plus. I have a USB hub but doesn’t seem to function with the player (the player only  sees one drive plug into the hub).  Can a Hub even be used with this player  or is there a  compatibility  problem with some USB Hub brands?

As far as I know, with the stock FW, you can still only connect one drive per USB port.

It’s not that hubs aren’t supported, per se, but they can only be used for connecting other USB devices, and not additional drives.
