I found my old ibooks (g4) touch pad before. It seems to have a usb controller, it has 4 leads coming from it, one black, all the rest brown.
The main chip on the board is.

I was hoping to muck around with it over usb. It has multitouch sensing (to some degree).

According to System Profiler, the trackpad is on the USB bus, so I'm 99% sure you could just hook up those leads to a standard USB connector and voila. I also know that some guy a couple years back took the leads from the trackpad connector and hooked up a bluetooth dongle internally so that he wouldn't have it taking up an external USB port. So basically, yes, it's USB
I have seen a discussion about this before. I don't remember all the details, but the bottom line was that some iBooks are using USB and some are using an older proprietary protocol. So it could be either one.
Since there are four wires, it's likely to be USB. If you want to try it out, follow these guidelines:
But don't do this if you don't understand what I'm saying here. I'll take no responisibility for your actions.
1) To a 99% certainty, black is ground. As long as black is correctly connected, the risk of frying something from misconnecting the other wires is small. However, connecting anything but USB ground to the mousepad ground will immediately fry it.
2) Next step is to find +5V. Follow the path from the black wire (Ground) on the circuit board until you reach a capacitor. +5V should join with Gnd at a capacitor.
3) When you're fairly certain you got Gnd and +5V right, it's time to get the two data pins right. There are only two possible ways to connect the last two pins, and of them is correct. Connecting these two pins the wrong way around will not permanently damage anaything, but it obviously won't work.
Good luck!
