    Downloaded the GUI program and tried to connect the cable. The end doesn't match the aircraft lead. Any help?

    I pulled it out from the main battery compartment. As per instructions on the GUI program.

    Your'e correct the connector should have 3 wires (red, white, blue) and should be visible when you open the battery door. The connector cable; are you using the one with the usb connector on one end.

    Yes GUI cable has USB connector on one end but the little block connector on the other end is not compatible.

    It is wider with more tiny contacts. It's a different kind. Maybe it fits another model? But it won't fit mine.

    If the end of the GUI cable is too small it's because that end of the cable connects to the camera. Disconnect the piece that is 3-4 inches long and then the GUI cable should hook to the bird

    Now when I plug the GUI cable into the USB port the computer won't recognize it. How do I download the correct USB driver?

    The USB cable is a simple USB to serial converter with FTDI chip.
    The driver can be found here: D2XX Direct Drivers

    Once the driver is installed correctly then you see another device in device manager section "Port (COM & LPT).

    Connect Q500 with USB, start the GUI and then switch on the Q500. It should be recognized on the COM port that is indicated at device manager.

    This has really been a problem. After having downloaded the driver and tried the USB GUI interface plug in several different computers I am convinced that the plug is faulty. It does not show up no matter how I power up the copter or whatever. The LED on the USB plug does not light up and I am unable to connect to the machine to update firmware. Anybody else had this problem? I really think it's a bad GUI cable.

    Glad you found this thread.

    Might try seeing if Yuneec will send you another. If not, buy one from Carolina Dronz

    Did all this. Still nothing showing up when I plug in the cable, and no led on the USB plug.

    I use all of this on two MacBooks. I find that restarting my laptop when it won't see my copter in the GUI corrects the issue.
