This coupler features a male USB A type connector at one end and a female USB B type connector at the other end. This is useful if you need a USB A M/M cable and only have a USB A to B M/M cable handy. It is compatible with USB 2.0 and backwards compatible with USB 1.0/1.1 connections.
Note that the maximum reliable length for standard USB cables is about 15 feet. If you need to extend USB longer than that, we recommend the use of one of our Active USB Extender Cables
