Target Disk Mode on a SSD in USB 3.0/3.1 enclosure

Hi all

I am planning to make a clone of my internal Yosemite boot drive using Carbon Copy Cloner.

My question is: If I clone this to an SSD in an external USB 3.0 enclosure, would I be able to use Target Disk Mode to selectively boot over USB 3.0? There have been postings but mostly focus on how to but over Thunderbolt or FireWire.

Also has anyone tried this on a USB 3.1 (Gen 2) card and see if the Target Disk Mode works?
