I believe the old case was 2.0 (maybe not high speed 2.0); the new one is 3.0. I used the same USB cable (2.0) as I only expected 2.0 speed - and the power is separtate.

Even on the old case, I had to power-cycle the modem top get it to find the external HDD.

You can't use a USB 2.0 cable on a USB 3.0 device. Has to be a 3.0 USB cable. One with the blue connector plug at each end.
