    Default Longer USB Cord Communication Issues

    I have to move the location of my controller and need to lengthen the USB cord. I purchased a 32 foot USB 'Repeater' cord online and tested it with the FPPP. There was no communication from the Pi and the controller. When I tried the cord on my laptop I got a message saying that drivers were being installed on the computer for the cord. Would this interfere with communications between the Pi and the Mega 2560? When I tested the original USB cord with my laptop, sequences played and the controller worked. When I tried the original cord with FPPP, there is no communication with the Mega, any ideas or suggestions?

    get a different "Active USB Extension Cord"
    there should not be any drivers, they are "supposed" to be "transparent".
    i have one for a non-blinky project and its seemless, just works

    Have started process of returning cord but my problem is that now the FPP will not communicate with the controller and I can't figure out why.

    If the extension uses RJ45 connectors between the two ends, check to make sure there isn't a crossed pin in the female connectors. They can get bent....

    Wilmar, that is the exact cord I tried and will be returning. I have a usb cord already installed in the controller that is 20 feet and worked great all last year. When I tested the new extension (attached to old usb) I could not get the Pi and mega to work. I then tried with the original and still can't get the controller to run a sequence through the Pi. I am able to run sequences via Vixen (on my laptop) and the original usb cord. Any suggestions?

    Hereís the one that worked for me
    These cables are hit and miss some work some donít thatís why I love using amazon prime easy returns . Just sucks thereís not much quality control with these things.
