    found my fix....

    when the apm reconnects you go to device manager and install new driver for the apm then it connects to flip... thanks

    Update...
    The apm on table watching gimbal shows the ghost glitch im experiencing occassionally..
    Today the apm worked well alti hold gps lock and stable all worked right..

    Only had a few ghost glitch commands...

    The gps rate i think is high still ..


    Anyone know if the mediatek v2.0 that ships with current apm is updated or needs flashed?
    Anyone know how to flash atmega without tool on 3dr apm? Mine has no boot loader i believe.
    When jumpered then shorted it disconnects from usb then gives the 3 low tone beeps stating error usb not recognized.

    I have lowered the hz to 20 to make sure and isolated apm on foam

    Did you get the APM 2.5 from 3DR? They should have the bootloader loaded.
