Guys... I am running Vista Ulimate. This is blowing my mind. I have two USB memory sticks. One is a Sandisk and the other is a Kingmax. The Sandisk works fine, the Kingmax can not find the correct mass storage driver anywhere. I have tried everything that I can think of and did tons of google searching so I am assuming this is a MBP issue. I even tried forcing another driver, looking at how the driver is on the sandisk card etc. How can one work and not the other!!!!
