Re: [PD] Comport can't read serial devices when soundcard is plugged in

I don't think it got through....

Well I'm interested, where did you post it to?

        I'll try this tomorrow, and i'll let you know if it works.

            I m pretty sure it's not related to the hardware, as it
    works
            perfectly fine in windows. I believe it has to do with the
            firmware.

                If you are plugging and unplugging the arduino it's
    possible
                the OS doesn't detect it properly. I know there were
    issues
                with the FTDI driver not reporting when the device
    had been
                removed, that caused Pd to hang.
                As long as your resistors are more than about 1 kOhm it
                should be OK.
                If you write ones to the input pins they will have
    internal
                pullup resistors enabled, so a switch that connects
    the pin
                to ground when it's on will work.
                And the pots should be wired like this:

                5V
                \
                /
                \<----Pin
                /
                \
                GND

                Anyway you say it works once it connects, so it's
    probably
                not the hardware, except possibly the cable/connectors.

                    I don't get random dropouts once it's connected
    (I used
                    it for 2 ours in
                    Pd and it worked fine all the time), but it just
    doesn't
                    appear (either
                    in the Serial port menu of the IDE, or in the device
                    list that comport
                    outputs) randomly. Do you think that this could
    still be
                    caused by
                    something sucking up too much current? There's
    nothing
                    special connected
                    to the board : 2 pots, and 8 buttons (wired so that
                    their rest position
                    is High).
