I have a hard drive that is powered via usb and I know you need to plug both of the USB cables from the Y into the same usb 'block' (you can't plug one in the front and the other in the back). If you were doing that, try plugging them in next to each other. Otherwise I think it's a usb problem. That's easily detectable by using a jump drive in the same ports and check /var/log/messages or dmesg. Also, if it is bad usb hw on your myth box the hub won't fix it (which is more reason to try one). My usb hd has a slot for power, does yours? If so I'd suggest trying it.
