Keyboards and Keyboard/Mice Combo Sets

[Pepebuho]

Hi

I have a K750 keyboard.

Solar App only works on windows.

Is there any Solar App for Linux?

In case there is not, is there any API I could hook up to in order to make my own? How to I talk to the keyboard to fetch the solar level and battery level?

Thanks

Javier

Hi Pepebuho,

Unfortunately, the K750 is not supported for use on the Linux platform.

Best Regards,

Hi phillips. I understand that. Is there any documentation about how the application talks to the keyboard? I would like to roll my own application to do what Solar App does.

Unfortunately, I do not have any documentation regarding information on how the keyboard interacts with the application. However, the connection between the USB receiver and the K750 is through Radio Frequency (RF). Please see FAQ #20620 for further information regarding what to do if the Solar App doesn't detect your keyboard.

I know this may not be the answer you are looking for, but unfortunately we do not have access to the exact information you are requesting.

I would also love to be on the recieving end of any technical documentation on how to read the solar/battery status under linux.

I would gladly release software to the community if ever such information was to become available.

I've found the kernel patch from Nestor Lopez Casado that provides better support for the Unifying Reciever under linux, I imagine that'll make it easier to talk to the keyboard and get any status updates about power from it

I think it S U C K S HUGE  that your  long time  LINUX  users  are in effect given the FINGER  when we  wish to use  your products to ther fullest. 

You would think  that after TEN years  that Logitech would have  supported LINUX  by now.

Ordinary users  should not be expected  to compile  kernel drivers  to use  your products.

Hello,

I took a shot at creating a userspace driver for the "non-standard" features of this device (onboard battery charge and lux reading).  I'd be interested to see if it works for anyone else:

I tried your solar app python script and I have to say, it does somewhat work. I got annoyed with the garbage it would spit out so I installed virtualbox with winxp, bound the nano-reciever to the vm, and got a nice little app called USBTrace. I spied on the usb reciever and pressed my light key, and found it transmits differently than any of the kb.device.ctrl_transfer lines you have uncommented or commented out. Once I fixed this line, the script works flawlessly, and no more crazy garbage results!

Here is the line I used:

kb.device.ctrl_transfer(0x21, 0x09, 0x0210, 2,"\x10\x01\x09\x03\x78\x01\x00"),

I also took a little extra time to make a Gnome 3 gnome-shell extension based on this script, you can check out a screenshot here: http://talon.linux.sh/k750.png
