Hi list,

Matthias Urlichs from "bluez-utils" redirected me to this mailing list, 
so here's my story:

I'm using a "Logitech diNovo Laser" desktop under both Linux and Windows 
  XP and it works quite well. 
(http://www.logitech.com/index.cfm/products/details/AT/EN,CRID=2158,CONTENTID=10777)

But when I tried to pair another Bluetooth device with my PC under 
Linux, I realized that the dongle wasn't recognized as a Bluetooth 
device and ran in "USB hub mode" instead, allowing me to use mouse and 
keyboard transparently but preventing me from using it with other 
Bluetooth devices.

I filed a bug for bluez-utils at 
https://bugs.launchpad.net/ubuntu/+source/bluez-utils/+bug/83484 but 
Matthias Urlichs told me that this is not a bug in "bluez utils" and 
there might be some "USB driver magic" necessary to use the Bluetooth 
capabilities.

He was right about that: After uninstalling the "Logitech SetPoint" 
software under WinXP, the bluetooth device vanished from the hardware 
manager and the bluetooth stack found no device. Mouse and Keyboard 
continued working though.

Has anyone an idea on how to make this work under Linux? I'm using 
Ubuntu 6.10 on my desktop PC (but I also have a Debian Etch Server 
standing right next to me). More information can be found at the bug 
ticket at https://bugs.launchpad.net/ubuntu/+source/bluez-utils/+bug/83484

Yours faithfully,
Raphael Charwot
