3, Update Google USB driver in Android SDK Manager (in Eclipse) or search Samsung Galaxy Ace GT-S5830i driver

• HTC phone or Samsung : change Connectivity Option on phone to Charge only (Swipe status bar. Check notifications displayed). Some phone set it to some kind of Sync data so Windows can not recognize device.
