I have a Motorola Droid Razr Maxx running Android 4.0.4. I'd like to prevent ICS from mounting USB storage every time I plug it into a USB host. I just want it to charge by default. I am very dissatisfied that they took away this option in the upgrade from Gingerbread to ICS.

I am willing to do stuff in the terminal that requires root privilege to prevent this from happening, but I would be happier if there is an app for it. I want my phone to Charge Only when I plug it into a USB host.
