    Teensy loader not recognizing Teensy 3.2

    Hello,

    I plug in the Teensy 3.2 to the PC and the orange light blinks. I open Teensy Loader and press the button, the orange light disappears and Teensy Loader doesn't recognize the Teensy. I've tried reseting the PC, pluging the Teensy while pressing the button, changing USB cable, port... everything I read that could affect.
    What can I do so Teensy Loader recognizes y Teensy 3.2?

    Thanks

    Make sure you are not using a 'charge only' USB cable.

    On Teensy.exe Loader Menu is 'Help' - under Help is 'Verbose Info'. Open that and it will indicate when a Teensy is detected by the computer. If it doesn't indicate a device, especially when pushing the 'Program' button - it won't be able to program it.

    I've used this cable to transfer data, I'm not sure if that's what you mean by not a 'charge only'.

    This is the 'Verbose Info'
    04:34:59: Teensy Loader 1.21, begin program
    04:34:59: Listening for remote control on port 3149
    04:34:59: initialized, showing main window

    I opened the Teensy Loader before plugin in the Teensy and I pressed the button. No lines were added since I pluged the Teensy.

    What type of setup? Windows? 32 or 64 bit? What OS? Also which version of Arduino and Teensyduino?

    For example if you are running Linux, then the next question would be, did you install the udev rule file as shown in the instructions?

    But I am guessing Windows from the win32... mentioned in verbose...

    Wow, ancient 1.21 version!

    Try 1.30 or 1.31-beta1.
