I've had this happen on rare occasion with this macbook pro (last aluminum) but it's starting to become more frequent. The trackpad and mouse will just stop responding, entirely. System Profiler still sees it and it's on the USB bus, but the mouse can't be moved or clicked. Keyboard works fine. Ext usb mouse works fine.
The fix so far I've found is simply to sleep it, and wake it back up. I have the hotkeys memorized now (cmd-opt-eject) since I can't pull sleep from the menu. (I didn't try to close the lid but I'm betting that won't work either since the sleep sensor is in the trackpad?)
It's possible this is only happening when waking it from sleep, my memory on the events isn't very clear but it's a distinct possibility, in which case it's an issue of the trackpad not waking from sleep reliably.
Anyone else seen this?
I did look in console and there wasn't anything relevant in the logs.
