All mouse and keyboard devices use HID (Human Interface Device) profile.
Check if your notebook's Bluetooth supports this profile...

Yes it does, but Logitech tries to hide that. In their datasheet there
is no word about any profile used. They do not say that the mouse would
work with any other bluetooth dongle. Patrick Röder said in his review:

After that I am not so sure that the mouse uses the standard HID profile.

I think the review is incomplete, or the HID understanding is lacking then:

Page 8: http://www.logitech.com/pub/pdf/blue...h_faq_v1_2.pdf

"...if you already have a system with built-in Bluetooth and the HID
profile, you can directly connect the Bluetooth keyboard and mouse. The
Bluetooth wireless hub will be used only to recharge your mouse - no need to
plug it to your system."

Adolf, when I say "HID understanding is lacking then" it's not directed to
yourself

thx for that, I did not see the FAQ, and neither the product description
nor the datasheet said anything about this.

to my opinion logitech is not helping bt to become a standard like usb.

the mouse works fine with my d400 latitude, but only without using
drivers! :-( when you try to install you'll need to plugin the cradle,
but after install of "setpoint"(and deactivation of the cradle by the
driver because of existing bt solution) i canot use the mouse with build
in bt anymore. :-/
i even tried standard usb driver a.k.a. "mouseware" which normaly detects
usb mices (and my bt hub seems to be a usb device), but nothing - again
mouse stays not visible. :-/

very bad work logitech! i really thougt it will be as easy and
comfortable as it has been all the years. :-|

without drivers the mouse is not as percise and fast as mx technologie
allows it to be.

read about an ibm r40 with probs on this, installing newest driver solved
this but if drivers were installable ...

maybe someone knows a nice workaround ! plz help !

The mouse seems to have two work settings:

- HID standard: only basic functionality, left / right mouse button,
back/forward/scroll buttons cannot be used
This works with any BT dongle with HID supported.

- "Logitech" mode: all buttons and settings are accessible, full
functionality
This only seems to work with the Logitech Base Station.

I don't know if this is a technical issue (there are several bluetooth
stacks out there that maybe).


Do Microsoft Bluetooth mice work on any system supporting bluetooth or is it
the same there?
Can drivers be installed on non-MS-Dongle - Systems?

As I only have the DiNovo Desktop from Logitech and do not want to spend any
money on pointing devices, I don't know.
Maybe there is someone out there who can check this out for us...

Moin,

That looks like a stupid idea to me. Not stupid enough to believe noone
would do it, though.

It works fine with bthid under Linux/BlueZ and I can see no reason why
it shouldn't (except for the abovementioned extreme stupidity, of
course). I couldn't make it work with my Windows/Widcomm (Thinkpad
T30), but I didn't try too hard.
