Logitech Unifying Receiver Protocol?

Question

Is there a place where I can find documentation or an SDK about the Logitech Unifying Receiver?

I recently obtained a wireless mouse, which came with a Logitech Unifying Receiver (a small USB dongle that plugs into the computer and communicates with the mouse/other compatible devices (such as keyboards)).

I wanted to try writing an app for my smartphone that pretends to be a mouse and sends data to the receiver.

I was able to monitor the data from the USB bus by using usbmon, and could probably use that to hack something out, but wanted to know if I could find the info I need somewhere on the internet without having to derive it on my own.

I'm going to try using SL4A on Android, if that helps any.
