回複:USB 2.0 Problem

到control pannel -> System -> device manager -> delete all the USB setting -> restart your computer -> let system reload the device drive form the default setting

Hope this will fix your problem.


Also try to boot your computer from safe mode, 看看u***** port 的speed 是否仍然如此慢

also go to Microsoft web site downlaod all the update files. Hope this will work.
