Just got my Droid 4 a few days ago and I could plug it in to the PC and mount the SD card and transfer files just fine. The last time I plugged it in I clicked on "Charge Only" from the notification menu and now every time I plug it into the PC it doesn't give me the options menu to select USB Mass Storage, it only charges the battery, I tried a full factory reset and still no luck.
