It works under Windoze but in Linux the integrated mouse doesn't work.
Whilst it's forced me to learn some keyboard shortcuts, the mouse would help a lot. Any ideas?

This is my media PC. I run currently run Mandriva 2008 & use Kafiene to watch/record etc TV.

Did you do a search?
I found this (quite quickly) for you: http://wiki.linuxmce.org/index.php/Logitech_Dinovo_Mini
Perhaps that will help.

thanks. I did do a search but couldn't find anything. Re the link you gave me I tried the following:
edit /etc/modprobe.d/options
There's no "options" file in /etc/modprobe.d but there's ipw-no-associate.conf which contains "options ... lines". I added the line as given:
options usbhid quirks=0x046d:0xc71f:0x00020000
then as recommended
update-initramfs -u
no such command/script. I tried rebooting but that didn't do anything.
I'm a little nervous running commands as root when I don't really know what they do. My next "upgrade" will be to another distro but at the moment Mandriva 2008.0 is doing what I want. Can anyone translate the above to Mandriva?

Mandriva is built on Red Hat. The 'buntus built on Debian. They are fundamentally different in the ways they handle networks, modules, and other things. I don't have a Red Hat based system to play with.

Looks like your device works with 'buntu 9.04 at least:

It's not working with Red Hat (well, not "out of the Box") as of Dec 2009 (so probably not fixed yet):

I think that link I gave you tells you what to do to make it work, but the precise details are incorrect for your distro.

I suggest you either learn about how Mandriva manages module options, and edit the appropriate files,
-or-
Try and get it working from the command-line eg

Then plug it in and see if it works. ( No changes needed to initramfsif you do it this way ).
If it doesn't work you could try:
as mentioned in the above link at post #2

Oooops! No. You edited the wrong file. Please go back and restore it to as it was, or your wireless interface may be unusable (and you'll be wondering why?).

thanks for the help. I'd obviously been searching in the wrong places. For anyone else with the same problem, I've resolved the problem by pairing the unit with another bluetooth transmitter instead of the pre-paired provided one. By pairing it with a normal bluetooth transmitter then running hidd --search (as root while pressing the pair button on the keyboard) apparently Linux sees it as a HID (Human Interface Device) and knows how to deal with it. Works perfectly. There's a little blank spot next to the battery to store the provided usb stick.

Interesting.

But I am puzzled - BT is BT (unless your device's BT dongle / "provided USB stick" is very broken).

Maybe try the original BT dongle, and go through the steps you did to get it working with "another transmitter". I'd be interested to know if it then works.

If not, please plug in the "bad" dongle and post the output of lsusb so we can see that its USB IDs are.

Thanks.
