    It was not as easy as it had described. I ran the CD and manually ran it. However, the icon do not show on desktop. Called technical support, could not hear what the person was saying. Requested for instructions on how to set up by email, have not rec'd it so far.

    It was ok but for some reason, when my speaker got connected to my PC using this adapter the audio of my speaker does not sound good. The audio is behind from the video. It's not sync with the video.

    If you're using this to connect your XBOX controller to a PC, dont. It stopped working so I had to order the XBOX dongle & hopefully it will work with my controller. Redownloaded the driver and it wouldnt recognize the device. Just fork out the extra for the Microsoft version that will work.
