Bluetooth: not available (mid-2011 iMac)

Question

Bluetooth: not available (mid-2011 iMac)

Hi,

my bluetooth is not available after updating to Mountain Lion. The (bluetooth-) keyboard and mouse are working, but without scrolling, gestures or special keys (play, pause, fn..).

In recovery mode (cmd+r) everything works fine though...

I've done the following steps, which are mentioned throughout the community here:

- delete library/preferences/com.apple.bluetooth.plist

- reset SMC ( http://support.apple.com/kb/ht3964 )

- reset PRAM ( http://support.apple.com/kb/HT1379?viewlocale=de_DE )

- Started Mac with all devices off & auto-login

- repaired disc permissions

- created new user

- reinstalled mountain lion

Nothing has helped yet..

This is the console log (search string "bluetooth") after booting:

same issue here.

it came up this morning after a security update, a java update and ard update.

getting log errors like:

9/26/12 11:06:11 AM	kernel	IOBluetoothHCIController::setupHardware -- failed to get the buffer size from the Bluetooth module -- re-enumerating device
9/26/12 11:06:11 AM	kernel	E:[AppleUSBBluetoothHCIController][InterruptReadHandler] Received kIOReturnAborted error - no more retries - bailing out.

9/26/12 11:06:36 AM	kernel	[[0x8597000] Req OpCode 1005 from: kernel_task (0) status: 00 state: 2 timeout: 5000] Bluetooth warning: An HCI Req timeout occurred.
9/26/12 11:06:36 AM	kernel	IOBluetoothHCIController::setupHardware -- failed to get the buffer size from the Bluetooth module -- re-enumerating device

and "Bluetooth: Not Available" in the menu bar.

the preference pane no longer shows.

reinstalled 10.6.8 combo, but no help.
