I have seen this issue all over the web with other phones as well as mine. So maybe on of you fine folks can help me.... Every time I plug my phone into the PC, I am supposed to be prompted to select: Mass Storge, Kies, or Music Player.... I normally select Mass Storage so I can edit files and blah blah blah. Well my phone will prompt me, I make my selection, and nothing happens! I have found the drivers for both Kies and USB on The Samsung site and installed them. I have uninstalled and reinstalled via control panel. My phone used to connect with no issues, prompt me, and then do what I choose for it to do. NOW IT DOESN'T FOR SOME REASON. It charges, but yet my pc all of a sudden can not recognize the USB. WTF happened? Can some one help me?
