    HI all,

    I am running Qt application on "Beaglebone black".
    But Keyboard and mouse are not working.

    Though I set the environment variable like:
    QWS_KEYBOARD=usb:/dev/input/event0
    QWS_MOUSE_PROTO=tslib:/dev/input/event1

    I am unable to use the Keyboard and mouse. Can I know the reason for this?
    How do I get my mouse and keyboard working?

      Hi,

      You should also add which version of Qt you are running on your board

        I have cross complied Qt4.8.6 source and have transferred the libraries onto the board.

        I don't haven't installed Qt on the board.

          There's no usb driver for QWS_KEYBOARD tty or linuxinput

          For the mouse, did you properly installed tslib ?

            Yes I installed tslib correctly. I have cross compiled the tslib and have transferred it into the device.

              Are you sure it's loaded ? Did you configure it properly ?

                I am sure about the configuration that I have done correctly.
                But i don't know whether its loading or not.

                  What do you get when running your application with the QT_DEBUG_PLUGINS environment variable set ?
