FILE: usb_ex4_dev_bulk.c
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.
SCIA, connected to the FTDI virtual COM port and running at 115200, 8-N-1, is used to display messages from this application.
A Windows INF file for the device is provided under the windows drivers directory. This INF contains information required to install the WinUSB subsystem on WindowsXP, Windows 7 and Windows 10. 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. Project files are included to allow the examples to be built using Microsoft VisualStudio. Source code for this application can be found in directory ~/C2000Ware/utilities/tools/{Device}/usb_bulk_example/Release
