    Teensy Programming without Windows Drivers

    Hi all,

    perhaps the topic name wasn't the best.

    Currently we are using TyQt to program a number of teensy's on a computer with the arduino environment.
    Problem being that windows seems to spend ages installing drivers for each new teensy that is connected, so takes a while before TyQt can pick them up.

    Is there a way of programming them without having to do this?

    Thanks in advance,
    Cosford.

    The problem is that windows "installs" the driver for each combination of vid/pid and serial number. You can tell windows to use the same driver independently of the serial number of the plugged in Teensy.

    . Scroll down to IgnoreHWSerNum

    That worked for me.

    Perfect. I figured that was the case. I'll give this a shot.
