        cite="mid:b1d79cdb-11c8-f3a1-9965-3bb723131925@xtra.co.nz">Just
        compiled an Arduino LoRaWAN demo sketch, and programmed it into
        a SparkFun SAMD21 Pro RF. <br>
        <br>
        Post programming, the blue LED appears to be on (or flashing
        fast), and the Arduino IDE is no longer able to find/program the
        unit. <br>
        <br>
        Win7 Device Manager reports the USB device under 'Other devices'
        "Sparkfun SAMD21 Pro RF" with a VID of 1B4F, and PID 214F there
        is also a yellow exclamation point indicating that the
        associated USB drivers have not been installed. <br>
        <br>
        A search of the web indicates that the bootloader has been
        corrupted, but I am surprised that the hardware can still
        enumerate a USB device - mind you, I know nothing about this
        processor. <br>
        <br>
        ----- <br>
        <br>
        So the short-and-sweet question: anyone seen/fixed this issue
        before, it seems like a popular way of bricking these
        (expensive) boards. <br>
        <br>
        I have found the bootloader hex/binary, and fetched a copy of
        Atmel Studio (870MB), just need to find a cheap, readily
        available, and compatible programmer. <br>
        <br>
        Comments please. <br>
        <br>
        Regards, Mark <br>
