USB Generic Bulk Device (usb_dev_bulk)

+//! +//! 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:/StellarisWare/windows_drivers directory of StellarisWare +//! 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 ``Windows-side examples +//! for USB kits'' package (SW-USB-win) on the installation CD or via download +//! from http://www.ti.com/stellarisware . Project files are included to allow +//! the examples to be built using Microsoft VisualStudio 2008. Source code +//! for this application can be found in directory +//!
