- Minimal implementation of a USB serial port, using the CDC class.\r
- This example application simply echoes everything it receives right back\r
- to the host.\r
-\r
- Windows:\r
- Extract the usbser.sys file from .cab file in C:\WINDOWS\Driver Cache\i386\r
- and store it somewhere (C:\temp is a good place) along with the usbser.inf\r
- file. Then plug in the LPC176x and direct windows to the usbser driver.\r
- Windows then creates an extra COMx port that you can open in a terminal\r
- program, like hyperterminal. [Note for FreeRTOS users - the required .inf\r
- file is included in the project directory.]\r
-\r
- Linux:\r
- The device should be recognised automatically by the cdc_acm driver,\r
- which creates a /dev/ttyACMx device file that acts just like a regular\r
- serial port.\r

- When an IN request arrives, the callback is called immediately to either
