My docking wont reckognise my usb

For some reason the dock option wont reconise my usb I have tried running it as an administrator and it still wont work help.

  1. has your USB been formatted on your xbox 360.
  2. you could have an outdated version of horizon. delete the older version from your comp and install from Here.(i am aware there was a problem with horizons device explorer a while back due to an update on the 360).

FAT32 FORMAT
