I have a USB keyboard plugged into the MacBook, and I have three keymaps set up. I don't tend to intentionally change them during the course of the day, but I do occasionally do so inadvertently. If you want to know the details of the USB keyboard, comment #30 above includes the output of hwinfo. It sounds like you think this might well be the trigger for the bug.
