Not aware that any exist. Windows should just see it as a keyboard, nothing more.
However, since Windows still lacks a USB device tree (something Macs have had since Mac OS 8 days), it's hard to tell exactly what it sees. Windows 8 shows both a HID keyboard and a HID mouse present when I plug in my blue cube. I guess the Cypress chip does mouse support as well, and they just didn't wire up the mouse socket.
Sounds like the PC is messed up to me.
