Connect PC to laptop with android
It's possible if you are using Cyanogenmod even without any 3rd party software:

Connect the phone to the PC and enable USB tethering. Then create a hotspot on your laptop and connect your phone to it.

After that, your phone shares it's WiFi connection to your PC, so you can transfer files and use internet.

If you're not a CM user then try using PdaNet+
