When I first connect ASUS transformer to my computer, my Windows XP installed MTP driver with yellow exclamatory mark in Device Manager. Then I download driver from ASUS, but after I uninstall, update or restart PC to reinstall ( before and after install Pad Pc Suite), Device Manager is still showing MTP driver. Could somebody help me? Also, there are 3 sub folders of the driver - Android, MTP and tethering. I tried first 2. Which one is correct one?
