I was having the same issue. Has nothing to do with the cable type you're using (i mean, besides it being a micro usb cable, obv).
Connected my droid razr to my comp and it wasn't responding. All you need to do is restart your phone. You do this by holding the power button and the down volume button at the same time for 10 seconds. Once it restarted, it's been connecting to my comp no problem. Charging and accessible.
The only way I got it to work was by installing the Motorola Drivers.... Google "MotoHelper_2.0.53_Driver_5.2.0.exe"
I know this thread is a year old, but I don't want to start a new one for the same thing. I have no "charge only" option when I connect my phone to my computer. The three options I get under USB computer connection are: mass storage, Media device (MRP), and Camera (PTP). I have tried two different usb cables, I have tried restarting my phone and I have installed the Motorola driver mentioned in the last post (am I supposed to see this somewhere or do something with this driver?). Still, there is no option for charge only. The phone looks like it's charging, and if it has over 50-60% charge already, it seems to charge (slowly) but if I plug it in at say 20%, it just stays at 20%. Sometimes it will show it's charging and lose power in the process. I am at a loss as to what to do here. :blink:
That's normal. I think charge only option disappears after ICS. If you see the lightening bolt indicator you're charing. The dial only moves in 10% increments and that low can take a while to move to 30% so normal.

I am guessing the computer just doesn't have the charge power of an outlet and when the charge is less than 30%, it loses power faster than it charges it, and when it has more it takes hours to get up 10%. Does that sound accurate and normal? If so, I will just have to know I cant depend on my computer to charge my phone when it is too low.
