I have a 12" powerbook (jan 05 model) and have been using the safe sleep/hibernation hack in order to get rid of that stupid blinking light at night when i sleep. since 10.4.4 though ive been finding that when the computer wakes and loads into tiger, no usb devices are found; removing them and re-inserting them does nothing; even the trackpad fails to initalise. anyone else experiencing this?
