This device cannot start. (Code 10) [Arduino Mega R3, Win7 64-bit, IDE 1.6.9]

Hi,
I'm really scratching my head to find out why is my W540 Lenovo is refusing to work with the Arduino.inf.

I've up & down on this forum and elsewhere to find a solution but I don't seem to help myself.

Whenever I scan for a new HW it selects the "Intel R Active Management Technology - SOL (COM3)". If I point out the "...Arduino\drivers" location then Arduino.inf and later selecting Arduino Mega 2560, the result is "This device cannot start. (code 10).

The board is "MEGA 2560 R3" made in Italy. The power LED is ON and the L LED blinks every 10s.

I've already tried:

  • Reboot
  • Uninstall USB Controllers
  • Disable firewall
  • Windows Update
  • Changed USB cable

It still doesn't work.
Your help is highly appreciated.

Thank you
