Re: DRIVER NEEDED: Logitech cordless mx duo (Windows XP Professional) [USB]
Logitech website has no mention of this model so it must be an OEM product made to be packaged with a computer when it's first sold. If it did come packaged with a pc, the place to get the driver would be from the pc maker. However, you might be able to find one or more of the Logitech drivers that will work. You won't know until you try them:
It was also sold by mass distributors like Geeks, MWave, etc. Logitech doesn't support those mass distributed devices so you may be out of luck unless some good Samaritan has the original disk and is willing to upload it.
I found this tidbit of info on another website that might help:
This product is basically a combination of Logitech’s highly-acclaimed MX™700 mouse and the Elite™ keyboard.
So those drivers from Logitech website should get you going.
