Aha, great idea. I've been browsing about in the mac os file system, and it=
=20
does seem to support several bluetooth devices.. I'm specifically intereste=
d=20
in "BroadcomUSBBluetoothFirmwareDownload.kext" which sounds likely. I'll fi=
nd=20
out the exact hardware used later.

I see there _is_ a linux driver for a USB broadcom bluetooth adapter that=20
uploads firmware. I'll try that one out in a bit - hopefully it is just a=20
matter of adding the correct USB IDs.

CCed to the bluetooth list in case anyone can throw light on this.

> Weird eh? It says its subclass is a keyboard/mouse!

A friend has just pointed me to:

http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/72101/wo/oT=
5zorkeg3cH25IQOn622ueI85D/1.0.0.11.1.0.6.9.5.19.0.1.0.1.1.2.1.0.15

Maybe my powerbook is booting up with the bluetooth device in a=20
'compatability' keyboard/mouse mode to support that bluetooth keyboard, and=
=20
it needs switched into 'normal' bluetooth mode somehow.
