Connect to the internet using USB and PC

[galw]

Is there a way to download apps/maps etc. by connecting my lumia to my PC using USB cable?
I want to download some big files and my WiFi is dead.....

what do you think about blocking the option to download big files using cellular network?

WP7 does this, but as far I see, WP8 doesn't. I need this too
