Interesting... what is the exact symptom ? trackpad and keyboard
not working any more ? I don't think the semaphore thing would
change as it's quite specific to the ADB probe sequence.
Do you get things back if you send ADB flush commands to the
trackpad and/or keyboard ? (You can do that from userland
via /dev/adb).
