I keep my USB cable at work, hooked to the USB on the side of my monitor. I have a makeshift "dock" that I set it in to charge and to pull pictures. (I use my droid to take pics of things I need for work, then I hook it up so I can email or print the pics). Sometimes when I plug it in, it's like it doesn't see it. Usually I get the option to MOUNT or DON'T MOUNT, but if I don;t, I have to move the cable to the other USB port on my monitor, then it works. Is there a manual mounting option somewhere in the menu?
