I have a microSD in my phone and It comes with a usb plug but when I plug the phone into the computer it desnt even recognize it. If i go to music > sync it says connecting but never connects. But then if I go to usb mass storage it shows up on the computer but the files I drag into the folder never show up on the phone. Oh and I also out the bluetooth on the whole time. Am I doing something wrong? Is there any way to put music from my mac to my phone just through the usb connection or do I have to get a scan disk reader to do that? thanks.
