Once fully booted, reconnect the device. Good luck! justinshn March 18, 2011 3:21:27 PM Hi there, I had already tried all that unfortunately. It seems like windows did something with the drivers from silicon labs that they fixed in the next couple days as it works now. For those who might have this problem with other devices though...you can simply disable the driver enforcement by pressing F8 before booting the OS. Thanks much! Can't find your answer ? Ask !
