I just got a Motorola Droid Razr HD Maxx and also a Motorola Droid Razr M. I'm trying to connect them to my PC with operating system Win 7 64 bit. Used the provided USB cord. Nothing happens with either of them. The PC is not recognizing them as drives. How do I transfer pictures, music from my PC to my 2 phones? Tried it on 2 computers with the same operating system. Nothing. Are there some settings on the phones? Do I download some driver for my PC? Also, how do I copy contact lists from 1 phone to the other. Thanks
