Just one guess: I have experienced a similiar issue when installing 
NetBSD to a pretty modern Intel NUC device. In my case the root cause 
was that the device exclusively has a XHCI (USB 3.0) controller, but no 
UHCI / EHCI. As NetBSD 7.x only offers support for UHCI / EHCI, the USB 
3.0 controller was not recognized at all and rendering the kernel unable 
to find a device where to look for the root filesystem. The reason why 
the kernel is still loaded from the USB 3.0 is that the bootloader is 
probably using some BIOS / CSM compatibility stuff.

Could you try NetBSD 8.0 Beta[1] on the same device? The amd64 build has 
XHCI enabled by default and this worked for my case.

Kind regards,
Matthias
