I was in need of a USB 2.5″ HD enclosure and decided on a Vantec case because then I would not have to worry about opening the box and finding one of those stupid USB A to A cables. Wrong. Maybe I’m just behind the times though and this is OK with USB 3.0? If you would like to avoid this product, it’s a Vantec NexStar CX (NST-200S3-BK).
A fellow turbo-nerd on IRC pointed out that Wikipedia has a nice little matrix of USB connectors and it says that A to A is “non-standard”
existing for specific proprietary purposes, and not interoperable with USB-IF compliant equipment.
My previous issue with a Vantec product is here: Who let the smoke out
