- UsbSerialDriver is now a discrete interface.
- UsbSerialDriver provides getPorts() method, returning one or
more usable UsbSerialPort.
- Use of UsbDeviceConnection is deferred until open(),
making it possible to probe for ports without
permission from Android.
(Thanks to Felix for inspiring some of these changes).
Even though they are not being used, might as well set them right. The other option would be to delete these four lines. For reference, http://www.beyondlogic.org/usbnutshell/usb6.shtml

Original commit message:
New driver for Prolific PL2303
A new driver for Prolific PL2303 devices, which is more or less a port
of the "pyprolific" driver from https://github.com/eblot/pyftdi
Demo now consists of two activities:
- DeviceListActivity shows all usb devices (including unsupported ones)
in a ListView.
- SerialConsoleActivity dumps the data stream for a device selected in
DeviceListActivity.
acquire() is renamed and deprecated in favor of findFirstDevice().
findAllDevices() is added as new functionality.
Internally, probe() now returns a list, allow a (future) multi-port
device to return multiple drivers, one for each port (googlecode
issue #14).
