I can't connect my Samsung Galaxy SL GT-I9003 via USB I can't connect my Samsung Galaxy SL GT-I9003 via USB. When I try to connect via usb mode the phone doesn't respond, it only charges. I tried restarting and restoring my device, but it still won't connect. I want to update my Android OS from Froyo to Ginger Bread.
Go to start.
Type device manager.


Do you see some icon with a yellow triangle exclamation mark in it?
If so, you probably did not install any drivers. Install the 
Samsung USB driver or the Google USB driver.
