[PATCH] USB: Prevent hid-core claiming Apple Bluetooth device on new …

…G4 powerbooks

To recap: My new G4 powerbook has a bluetooth device that boots up in
what apppears to be a compatability mode - it looks exactly like an HID
keyboard/mouse device.

A special command sequence is sent to switch it into full bluetooth
mode. When this occurs the original HID device vanishes, and a new
(bluetooth HID) USB device appears on the bus with a different product
ID.

The original thread is here:
http://sourceforge.net/mailarchive/message.php?msg_id=12532263

The attached patch adds the device to the hid-core quirks so that
hid-core ignores it.
