My first big USB AVR-USB project with ATmega8. Using free avr-usb library @ http://www.obdev.at/products/avrusb/projects.html
It's perfect sound VU meter for PC which operates only on USB cable. So you don't have to connect any audio jack cable. It takes power from USB too.
In AVR there's a code in C . In PC is my app in C# which records output from soundcard and is sending some averaged data to my device.
Nice! What's running on the computer that feeds data to the USB?

I'm using #usblib wrapper for libUsb C library. On PC there's my app in C#. It's just simple sound recorder but it don't save sound to the HDD but sends some averaged samples by USB.
