Title: Useless with external hard drives; Okay for charging ps3 controller.
Review: I ordered this 'cos price was low. Tried connecting a Western Digital Elements 500gb portable hard disk and a 120gb hitachi 2.5 inch sata hard disk in an Acomdata Tango enclosure to my laptop using this. Connection is not at all stable. It connects and then disconnects immediately and then connects again and on and on. If left connected it'll probably damage the external hard drive. So right now, I'm using it only for charging my PS3 controller. Seems to be good for that. Hence the 2 stars.
