Detailed Description

This file contains USB core functions not strictly necessary for USB to actually operate. This includes:

• Printing debugging, informational, and error messages
• Printing the state of the USB (through usbinfo()).
• Obtaining human-readable string descriptors from USB devices.
• Translating certain constants into strings describing them.

To disable all the above functionality, set USB_EMBEDDED to TRUE in usb_util.h. Obviously, only do this if you know what you're doing.
