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

Control transfer handler.
This module handles control transfers and is normally installed on the
endpoint 0 callback.
Control transfers can be of the following type:
0 Standard;
1 Class;
2 Vendor;
3 Reserved.
A callback can be installed for each of these control transfers using
USBRegisterRequestHandler.
When an OUT request arrives, data is collected in the data store provided
with the USBRegisterRequestHandler call. When the transfer is done, the
callback is called.
When an IN request arrives, the callback is called immediately to either
put the control transfer data in the data store, or to get a pointer to
control transfer data. The data is then packetised and sent to the host.

/**
* \defgroup psock Protosockets library
* @{
*
* The protosocket library provides an interface to the uIP stack that is
* similar to the traditional BSD socket interface. Unlike programs
* written for the ordinary uIP event-driven interface, programs
* written with the protosocket library are executed in a sequential
* fashion and does not have to be implemented as explicit state
* machines.
*
* Protosockets only work with TCP connections.
*
* The protosocket library uses \ref pt protothreads to provide
* sequential control flow. This makes the protosockets lightweight in
* terms of memory, but also means that protosockets inherits the
* functional limitations of protothreads. Each protosocket lives only
* within a single function. Automatic variables (stack variables) are
* not retained across a protosocket library function call.
*
* \note Because the protosocket library uses protothreads, local
* variables will not always be saved across a call to a protosocket
* library function. It is therefore advised that local variables are
* used with extreme care.
*
* The protosocket library provides functions for sending data without
* having to deal with retransmissions and acknowledgements, as well
* as functions for reading data without having to deal with data
* being split across more than one TCP segment.
*
* Because each protosocket runs as a protothread, the protosocket has to be
* started with a call to PSOCK_BEGIN() at the start of the function
* in which the protosocket is used. Similarly, the protosocket protothread can
* be terminated by a call to PSOCK_EXIT().
