I've just bought an Asus with a OWC Mercury Pro enclosure. I need a longer USB cable for it but not sure which is the correct one, the box says it's a USB 3.1

This looks similar but the holes in the upper part of the B end look slight different

Has anybody bought a longer cable for their OWC Mercury Pro?

That is the correct cable it's a standard USB 3.0 A to USB 3.0 B

Great, thanks
