I originally purchased this just to connect a couple of USB devices, but since it arrived, I have successfully tested it, mostly just for fun, with a Camera, External HDD, Keyboard, Memory Stick, Mini Hub, Mouse and VoIP Phone. Since it is has straight connector for the micro USB, and not right-angled unlike some, both connectors fit well and aren't loose. This is important if you normally rest your unit in landscape orientation in a protective case, as I have. This means that it is not the cheapest, but sometimes you only get what you pay for. As recommended by others I have installed the low cost Nexus Media Importer App, for browsing the storage devices, including the multi-drive HDD. However, this doesn’t work with my particular camera, but as suggested in the Troubleshooting Help, I can just use the Gallery instead. So, if you only want to connect a camera, it is best to check it out using the Gallery first.
