ARM processor interfacing with USB flash drive

I'm choosing a class project for an upcoming microcontrollers class. The class uses an ARM processor.

One project I'm considering is to build a device that would record mp3's with a microphone and save them to a USB thumb drive. Then would be able to retrieve mp3 files from the thumb drive and play them. Okay so I guess it's basically just an mp3 player/recorder using an ARM processor.

My professor told me that the USB interface would be by far the hardest part. He told me I could use any resources I find (including code) that would help me handle that part of the project. But the problem is I don't even know where to start looking.

Can anybody help me?
