Using Logitech K400 wireless keyboard with Linux
Posted by on October 30, 2011
Besides the camera, I also bought a very basic computer yesterday equipped with the Logitech K400 wireless keyboard. It will be placed at home beside the LCD TV and be used as a media player and for some light-weight computing tasks. Linux is my favorite OS but I’m not sure whether the Logitech K400 can be used. The Logitech website only specify it supports MS Windows. This post is to confirm that K400 does work with Debian and Ubuntu. It works out-of-the-box with no configurations required.

Dear Sir, I thank you for your informative post.
On my way to buy one…
You are welcome.
And, just for the record, it works flawlessly for me as well (on Debian).
A *huge* improvement over http://www.mythtv.org/wiki/Wireless_Keyboards#iOne_Scorpius_P20
thanks you
?? Mine doesn’t. lsusb returns the logitech unifying receiver, but no functionality beyond that. Am I missing something?
Running xubuntu 11.10
Alex,
this is somewhat asking you to blow the dust (http://www.joelonsoftware.com/articles/customerservice.html), but .. did you set the small switch on the keyboard side to “on”?
If so, please post the results of an lsusb; I’ll try and have a look this evening at home.
A.
hah, yes, I did.

As you can see, we seem to have somewhat similar info on the wireless keyboard.
(You have other logitech devices, though, and I hope they don’t .. interfere. Have you tried removing the other devices, just for testing purposes?)
Otherwise, here’s the verbose version of lsusb for the k400:

If you have something similar, then there’s always the possibility that you were sold a defective unit, and your only option is obviously to return it.
Thank you friend!
I was thinking to buy one and this information was very important to me!
I’ll put it in a ATOM mediacenter pc i use.
