Here's a screenshot comparing the broken/working traces, with NAKs hidden: http://dev.laptop.org/~cjb/macntouch.png Both traces are from plugging in and hitting "a" three times. Here's a text file of the log from the failing case -- it shows that IN-NAKs are happening regularly after the final GetDescriptor (which you can get to in the file by searching for "9.534"): http://dev.laptop.org/~cjb/macntouch.log I checked to see whether /proc/interrupts increases with each keypress; it increases twice per keypress in the working case and not at all in the failing one. Any further ideas? I can't imagine what's wrong with my hardware. It works on other PPC laptops running Linux, though I haven't found another of the same model of Powerbook to test with.
