If you have your Wireless Media Stick plugged in your PC and no USB drives show up after a period of time (it can take up to 60s to show up) then you should perform a factory reset. Also check to see if your LEDs are operating properly (One should be solid green, the other flashing or solid green as well).
If you have only one LED solid and/or the stick doesn't show up on your PC/MAC then please perform a factory reset -
While the stick is plugged into your PC (ie powered on) take a paperclip and press the 'reset' button on the side and hold it in and count 11 (eleven) flashes of the LED then let go of the reset button.
The stick should come up fine after this reset.
