+usbcomp_msd_cdc
+=====================
+This project implements a USB composite class device that includes
+a mass storage device and a virtual COM device.
+
+To run this example, you must attach a USB cable to the board. See
+the "Getting Started Guide" appendix for details. You may also
+connect the LPCXpresso board to a base board from a 3rd party tool
+partner.
+
+When downloaded to the board and executed, the PC will first recognize
+a USB mass storage device and mount a new drive that contains a text
+file, and then it will recognize a USB "VCOM" device and ask for a
+driver. Point windows to the .inf file in the usbcomp_msd_cdc project
+directory to cause Windows to install the default USB serial driver.
+
+At this point, you should be able to read/write files in the newly
+mounted drive and send/receive characters through the USB virtual
+COM port at the same time. The transmit baud rate will equal the 
+CDC port configured baud rate.
+
+One thing we have seen that can cause trouble with the USB examples
+is the Windows driver install. Since the example projects all use
+the same USB Vendor ID and Product ID, if you try out the HID
+example and then try out the CDC example, Windows may try
+to use the HID driver it had already installed with the CDC
+example code. To fix this, go to the Windows Device Manager,
+find the broken "HID" device and select "Uninstall." Then unplug the
+device and plug it back in. Windows should correctly identify the
+device as being a CDC device and install the correct
+driver.
+
+The project makes use of code from the following library projects:
+- CMSISv1p30_LPC13xx : for CMSIS 1.30 files relevant to LPC13xx
+
+This library project must exist in the same workspace in order
+for the project to successfully build.
