You need to load the USB 3 Host Controller and Hub drivers
at the beginning of the restore process. Then the reimage software should see the disk and image.
With Windows imaging you go to the load driver
option and select the 2 appropriate *.inf files.
I use WD MyBook Essentials usb2/3 HDDs. Even when the drivers are installed, you may need to wake the HDD up by physically disconnecting HDD power and USB the plugging back in.
It is a bit annoying with this fiddling but Windows will locate the image. The speed of the USB 3 reimage more than makes up for the nuisance.
----Store the drivers anywhere convenient. I have them on my Boot utility flash drive.
