[Bluez-users] Logitech diNovo/Desktop MX Bluetooth

[Bluez-users] Logitech diNovo/Desktop MX Bluetooth

[Stian Jordet]

Hi,

I've been searching the archives a bit. I found some references and talk
about the diNovo, but no real answer, though I understand that work are
progressing in this area.

Since Greg KH is claiming that my keyboard/mouse are faulty (keeps
reconnecting when using usb-serial adapter), I'm going to buy a new set
during Christmas, and I'd like to have one of Logitechs BT sets. Thus I
have some questions.

Will it work with Linux? I'm running 2.6 kernels. If not, what will I
need, and is this already developed? I saw something about a user-space
daemon called bthid. Does that mean that the keyboard can't be used
untill a user-space daemon has loaded? Can it be used with Grub, for
instance?

And one last question, will I be able to sync my phone using the
Logitech BT dongle, while both the keyboard and mouse is connected?

Sorry for all these question, but it's a rather expensive toy if I can't
use it :P Hope someone has any experience to share.

Please cc me if anyone has anything clever to say, as I'm not
subscribed.

Best regards,
Stian

the diNovo Desktop is working fine with Linux, but the code is in an
early phase of development. We have two implementations at the moment,
the one from Peter Klausler and the other one from me which is based on
the new Bluetooth library I am working on. Peter's code need some
patches to make the keyboard and mouse working and for 2.6 it also needs
a patch to support the uinput kernel driver. My code includes already
all the needed stuff, but there is no official release available and the
code only exists in the BlueZ CVS repositories.

The Logitech Bluetooth HUB is a little bit problematic, because it is a
HID proxy capable device. This means it has a HID mode and a HCI mode.
In HID mode it presents you a USB HID mouse and keyboard and you don't
need a Bluetooth stack on your PC to have it working. And in this mode
you can also use your keyboard in the BIOS and for Grub. The HCI mode
converts this HUB into a simple USB Bluetooth dongle and your OS needs
to support Bluetooth HID devices. Actually at the moment nobody knows
how to switch this HUB from HID to HCI mode and back.

This all means that you can use the diNovo desktop always with the
Logitech Bluetooth HUB in HID mode under Linux, but you can't use the
HUB for phone connections at the same time. You need an extra Bluetooth
dongle for this until someone figured out how to switch the modes.

Regards

Marcel

Thank you for your prompt answer (as always) :)

I already have a 3com BT dongle, so I will manage untill someone
eventually (and hopefully) figures how to switch modes. The 3com is a
bit picky as well [1], so it would have been good to get rid of it :)

Thanks for your great work with BT in Linux :)

Best regards,
Stian
