Doesn't work for Raspberry PI

Since I am in a stage where I am configuring a lot of RaspberryPi's, i got tired of unplugging cables from my pc and into my Pi and then back to my PC when i was done. I bought this device so all i had to do was plugin my Pi and press a button. I am not sure if there is a configuration problem with the RaspberryPi but the Keyboard/Mouse does not function. The video capability works perfectly though.
