I'm trying to help my daughter connect her Samsung Galaxy Stellar to the computer via the USB cable to use KIES and also transfer some files. For some reason, the cable will just start charging the phone and does not recognize it in any other way. There is no option in the pull down menu and the computer does not seem to be recognizing it at all. I've used the same cable and same computer with my Galaxy SIII and I have no problems, it recognizes it, etc. What can I do?
