The bluetooth chip in the new Apple MacBook Pro 5,1 (and I suspect the new Apple MacBook Aluminium although I don't have one of these to test with) does not work until it is manually reset by issuing a

hciconfig hci0 reset

The device is identified as (from lsusb -v):

Bus 004 Device 003: ID 05ac:8213 Apple, Inc.
Device Descriptor:
  bLength 18
  bDescriptorType 1
  bcdUSB 2.00
  bDeviceClass 224 Wireless
  bDeviceSubClass 1 Radio Frequency
  bDeviceProtocol 1 Bluetooth
  bMaxPacketSize0 64
  idVendor 0x05ac Apple, Inc.
  idProduct 0x8213
  bcdDevice 0.07
  iManufacturer 1 Apple, Inc.
  iProduct 2 Bluetooth USB Host Controller

Attached is a patch for the btusb driver in the linux kernel which ensures the device is reset when the driver is loaded.
