DUE and windows problems

Hey razer93, you sketch works perfectly in my laptop but with Windows 7 x64 SP1. Like you, I am using the native USB port.
I wanted to share a couple of things that happened during the first time I connected DUE to my laptop:

  1. Like lynchzilla, I got the red warning about the signature but Windows allowed me to override it.
  2. Windows recognized an 'Arduino Due X' driver but I couldn't make anything work! So I re-booted my laptop and the driver was gone; then, I re-installed the driver making Windows browse the arduino-1.5-windows folder and a 'bossac' driver showed up. Finally (and automatically), after few minutes, the Arduino Due driver (ver. 5.1.2600.0) took over again.
