Hi,
I'm having an odroid system with an powered usb hub for an usb hdd and connected nova td directly to the odroid.
I had the same error message after I replaced the powered usb hub with a newer one as a try to solve another problem (it was not the cause..).
In my case it seems that the new powered usb hub gives power to the odroid, because the leds were still on after I plugged of the power supply of the odroid!!
After I replaced the powered usb hub with the old one, the problem was solved.
So plugging of the usb hub temporary with having the nova connected directly and do a restart may be worth to see if it is the same problem.
