I had a "new" maple board (at least a year old, but new for me) that would not load the serial port driver.
The dfu driver loaded on windows 8 with the driver signing turned off. excellent.
The problem was I could not load the serial driver. It was like nobody was home once the board booted.
The issue was the serial port was not initialized on wakeup.
Some example programs dont seem to make the port work properly. If you load the AnalogOutSerial example it does work and will then bring up the serial maple device. Once it is in device manager then you can choose the maple serial driver.
Hope this helps!
