What I can say is that it never worked for me on Trusty with the 3.13 kernels and continues to not work with the mainline 4.2.5 kernel. Which USB port I plug it in does also not matter. Tried USB 3.0 ports on the back and two of the USB 2.0 ones. No dice. Same for the ones on the front of my machine. Luckily this thing can change to a mass storage device, but it's still a weird and annoying issue.
