USB Generic Bulk Device 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. 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. The device driver may also be downloaded from http://www.luminarymicro.com/products/software_updates.html as part of the ``Stellaris embedded USB drivers'' package (SW-USB-windrivers). 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.luminarymicro.com/products/software_updates.html . Project files are included to allow the examples to be built using Microsoft VisualStudio. Source code for this application can be found in directory StellarisWare/tools/usb_bulk_example. ------------------------------------------------------------------------------- Copyright (c) 2008-2009 Texas Instruments Incorporated.
