19.6 New Features in Stellaris USB Librar y

19.6.1 Add support for USB audio class in device mode. (Reference 9894)

This update adds support for USB audio device class to the USB library. The USB audio class

support only audio playback with volume control implemented as well. The audio device class is

implemented as a generic USB audio class and will work with any operating system that supports

USB audio class devices without the need for additional operating system drivers.

19.7 Bug Fixes in Stellaris USB Library

19.7.1 USB library enumeration code not properly clearing FIFO ﬂags. (Ref-

erence 10044)

When handling standard device request, the USB library was not always clearing the FIFO read

ﬂag when a new request was received. This could effect any commands that followed the request

that failed to clear the FIFO read ﬂag.

19.7.2 USB library not handling VBUS errors in OTG mode. (Reference

10100)

The USB library is not properly handling VBUS error interrupts during host enumeration in OTG

mode. If VBUS error occurs during enumeration, it causes the USB library code to hang in an

intermediate state and not properly turn off power and retry the connection.
