	* USB HID device (~~claims to be a~~ keyboard ~~maybe?~~)		* USB HID device (virtual keyboard)
	* VID:PID is <code>0xffff:0x0035</code>		* VID:PID is <code>0xffff:0x0035</code>

			If configured, it can also show up as a virtual COM port:

			* USB CDC device (virtual COM / serial port)
			* VID:PID is <code>0x0483:0x5740</code>

			On Windows 7 at least, it requires the ST CDC driver:

			On Linux it "just works".

== Software ==

There seems to be variants of two different pieces of "demo" software -- one written in C++ that can interact with the device over USB, and another written in Java.
