Hello,

i put infos and links on using the MS Bluetooth Optical Desktop under
Linux on
	http://www.iptel-now.de/HOWTO/BT_HID/bt_hid.html
(Many thanks to Peter Klausler for his page and the recent Linux driver!)

The page also shows 2 pictures of the PCB in the keyboard - it's
relatively small and i guess it has potential for reuse in other context
(e.g. in a wireless Twiddler or Twiddler-like chording keyboard that uses
BT).

The "Optical Desktop" is far from "cheap" - but at least at the moment
it's less expensive then serially attached BT modules (at least from what
i know).
Does anybody know more on that topic:
 - BT modules that easily interface with uCs (and are not to expensive)
 - uCs with USB host functionality that easily interface with the
     relatively cheap USB BT modules

Also - does anybody know more about the uC (Winbond W78LE812F-24) / BT
module cobination in the mentioned keyboard?
I'm hoping to collect some more info.

best regards
 ralf
