Mac mini bluetooth or multitouch failures after hibernating I recently purchased a Mac mini and have begun having a problem with bluetooth. I've made a bunch of changes to the system all at once, so some of the information I'll provide is probably not relevant.

I am currently running 10.8.5 (12F45) off of a new second hard drive that I installed (a Crucial M500 SSD). I have an Apple Extended Keyboard with an iMate ADB/USB adapter and a Magic Trackpad as my input devices. I had used this Magic Trackpad and keyboard with a MacBook Pro (running Lion) for about two years without any problems. 

The problem that I have encountered is that occasionally (not every time), when I wake the computer from hibernation (which it automatically enters after a brief period of sleep overnight), bluetooth is malfunctioning in a strange way. Bluetooth is indicated as on in System Preferences and in the menubar, but cannot be turned off. The trackpad is not indicated as connected. Here's the strange part: the trackpad still partially works. I just used it to wake the computer (not the power button). I can move the cursor around the screen and click on things if I press on the trackpad, but none of the gestures work – scrolling, swiping, zooming, etc. and I can't tap to click. When I go to the Trackpad preference pane, it thinks no trackpad is connected, and when I go to the Bluetooth preferences, the name of the bluetooth module shows as:



Here's what I've tried so far:


checked software update to make sure all updates are installed
unpaired trackpad from MacBook Pro
unpaired and repaired trackpad to Mac mini
reset NVRAM and SMC
killing blued process


None of these has had a lasting effect; killing blued never worked.

One of the things I've noticed is that when I wake the computer and this condition occurs, I see the following two messages in the Console:

kernel[0]: [AppleMultitouchDevice::willTerminate] entered
kernel[0]: [AppleMultitouchDevice::stop] entered


Whereas normally when I wake the computer, I get these two messages:

kernel[0]: [AppleMultitouchHIDEventDriver::start] entered
kernel[0]: [AppleMultitouchDevice::start] entered


I'm kind of at my diagnostic wits-end. I'm willing to try a fresh install of Mountain Lion, but I'd kind of like to know why this problem is happening so that I'm confident a reinstall will be a permanent fix. Thanks in advance for the suggestions.
As it turns out, the problem was one with either the iMate ADB/USB adapter or the Apple Extended Keyboard (AEK). Since the AEK requires an ADB/USB adapter, and I don't have another one around, I can't determine which component was the cause. Either way, since I replaced the AEK with an Apple USB Keyboard, the problem has not returned.
