Make sure you have installed all your USB drivers for the Samsung Galaxy Nexus to connect it with the computer. Download Samsung Galaxy Nexus USB drivers! Apart from just the USB drivers, there are a few more things that you need to take care of.

1. You need to enable USB debugging mode. This helps to connect your Android phone with the PC. See here: How to Enable USB Debugging.
