See some diagnostics from all of these machines below (relevant parts in bold). I have tried plugging it into a little single-board computer (Odroid N2), my MacBook Pro, and a Windows/Linux desktop computer, all equipped with functioning USB 3 ports.
However, I can only get the device recognized as a USB2.1 device, no matter where I try to use it. I have recently bought an Archer T3U(EU) v1.0, which, according to the specs and packaging is USB3.0 capable.
