The contact at Apple confirmed the only two options would be to tie in to the logic board upstream from the mouse/keyboard USB controller, or somehow magically figure out all the needed information to do it at the lower level (essentially duplicating the USB stuff on the logic board). At any rate, this person is in a position to answer the technical questions I had, and the feared/unfortunate end result is that it would be possible to accomplish my goal… IF I had a logic board too, not just the pad and cables. This person was kind enough to answer my questions, in return, I won’t give out that information. I’d rather not divulge the idea that led to this, but will say that the end result was several responses from someone at Apple.
The 3 ICs on the unibody touchpad cable are: On the unibody Macbooks, the combined mouse/keyboard USB controller IC is on the logic board ( as confirmed by ifixit) In the first link above, the older style touchpads incorporated the mouse’s USB controller IC into the touchpad PCB itself. The challenge is that the ribbon cable which connects the touchpad to Apple’s logic board is extremely small, has 3 ICs on it, and way too many tiny test points for me to realistically probe to pull this off. I had an interesting idea pop into my head earlier in the week, which was a potential way to get more information, or pinout/wiring diagrams of the parts I have, to move the project past its current standstill. No middle click, no two finger scrolling, terrible accuracy, yet I continue using it because the comfort level outweighs the negatives in my case.įast forward to this week.
Comfort wise, it works amazingly well, but the cirque pad, quite frankly, sucks.

I have a similar setup I made for work, but since I only have the choice between Windows XP and RHELinux there, I just used this cirque touchpad. I thought it would be a great way to create an amazingly comfortable mousing/typing combo by putting it between the two halves of my Kinesis freestyle keyboard, allowing me to minimize reaches for the mouse while maximizing comfort. Similar things have been done before, albeit not for these glass touchpads. ~6 months or so ago, I purchased a top case from a parted out 13″ unibody Macbook from eBay, with the intent to strip off the touchpad and make a DIY desktop touchpad USB device out of it.
