I have a new Gen 3 device and had to set it up with USB 2.0 cables because it wasn’t recognized with 3.0 cable. Once set up I have tried again with the 3.0 cable, purchased a new Monster 3.0 cable, updated Bios and Intel drives on my motherboard which drives the 3.0 port but still won’t work. It gets to the point where it is supposed to load drivers and then just stops. There is a single white light visible if you take of front cover. Any clues?
Is the card/motherboard you have listed as compatible from this list?

If not, it may not be compatible…
Still, I think it should work if you insert it into a USB 2.0 port.
