+//! <h1>USB Generic Bulk Device (usb_dev_bulk)</h1>

+//!

+//! This example provides a generic USB device offering simple bulk data

+//! transfer to and from the host.  The device uses a vendor-specific class ID

+//! and supports a single bulk IN endpoint and a single bulk OUT endpoint.

+//! Data received from the host is assumed to be ASCII text and it is

+//! echoed back with the case of all alphabetic characters swapped.

+//!

+//! A Windows INF file for the device is provided on the installation CD and

+//! in the C:/ti/TivaWare_C_Series-x.x/windows_drivers directory of TivaWare

+//! releases.  This INF contains information required to install the WinUSB

+//! subsystem on WindowsXP and Vista PCs.  WinUSB is a Windows subsystem

+//! allowing user mode applications to access the USB device without the need

+//! for a vendor-specific kernel mode driver.

+//!

+//! A sample Windows command-line application, usb_bulk_example, illustrating

+//! how to connect to and communicate with the bulk device is also provided.

+//! The application binary is installed as part of the ``TivaWare for C Series

+//! PC Companion Utilities'' package (SW-TM4C-USB-WIN) on the installation CD

+//! or via download from http://www.ti.com/tivaware .  Project files are

+//! included to allow the examples to be built using 

+//! Microsoft Visual Studio 2008.  Source code for this application can be

+//! found in directory ti/TivaWare_C_Series-x.x/tools/usb_bulk_example.
