We contacted the ODM to get newer firmware. They contacted Clevo, who told them that the Barlow Ridge chip in these machines is the B0 revision. According to them, the latest firmware available for the B0 revision is 14.6; they also state that the 56.x firmware is for the B1 revision and is incompatible. Is it possible that the problem is that the driver is written specifically for the B1 revision and only partially works with the B0 revision? Thanks for your help! Aaron
