+This is the Readme file for the libs-device directory. This directory contains
+code snippets which may be useful for USB device firmware.
+
+
+WHAT IS INCLUDED IN THIS DIRECTORY?
+===================================
+
+osccal.c and osccal.h
+ This module contains a function which calibrates the AVR's built-in RC
+ oscillator based on the USB frame clock. See osccal.h for a documentation
+ of the API.
+
+osctune.h
+ This header file contains a code snippet for usbconfig.h. With this code,
+ you can keep the AVR's internal RC oscillator in sync with the USB frame
+ clock. This is a continuous synchronization, not a single calibration at
+ USB reset as with osccal.c above. Please note that this code works only
+ if D- is wired to the interrupt, not D+.
