I have the Microsoft Wireless Mobile Mouse 4000 + Asus Transformer Pad Infinity (with dock). I connected the mouse to the USB port on the dock. I opened Joystick Center and enabled the J2T add-on, and set the IME thing on. Now, the keyboard shows up while searching, but the mouse does not!! I tried a wired mouse and it worked, but this mouse doesn't show up... anyone know why?
