This is not really a good device for learning. It is a USB
to serial converter and Prolific provides the driver so
that you can use serial API to talk to the device.

Anyway, you may want to take a look at the example
of using the async API.
http://sourceforge.net/p/libusb-win32/code/HEAD/tree/trunk/libusb/examples/bulk.c

If you want to use the sync API, it is also possible, just
write more data in one go and the speed should be faster.
