Query: Not enough power

I have an extension cord for this to get to the back of my PC. When I plug things into this thing, they simply are not recognized, such as a simple Sandisk 4GB Memory pen drive. Maybe it is because of the extension cord... I figured this would be underpowered. I love the targus one. It takes two ports on the PC but you get 4 so you net two.
