Hi,
I have the same problem as you, I need to restart the Nuc to light up the usb hdd.
The problem doesn't appear if I connect this hdd to another computer.
The "Deep S4/S5" option did the trick but I lose the ability to power on with IR remote.
Is there a solution to simply make this thing works without loosing some functions ?
I have Windows 7 64, bios 0032, all drivers up to date.
Thank you.
