Non-Unifying "NANO RECEIVER" confirmed working (just add the ID)

[Nephiel]

Hello,

Some Unifying-ready Logitech devices, such as the M305 mouse, come with a non-Unifying receiver. It looks the same, but instead of the Unifying logo it has "NANO RECEIVER" written on the case. The device ID of the nano receiver is 0xc52f.

I have M305 and M175 mice. both of them come with one of these Nano receivers. I added the ID to the code and your pairing tool worked, both mice pair successfully.

All it needs is a new define in line 29:

define USB_DEVICE_ID_M305_NANO_RECEIVER (__s16)0xc52f

and including this new ID in the comparison in line 59:
info.product != USB_DEVICE_ID_M305_NANO_RECEIVER &&

I'm posting this here in case you want to add it to the code.

Hi,

can you send me please the modified files? I want to "hack" my receiver which comes with M325 to work with other mouses. Thank you very very very much! jardadjart@gmail.com

@djart01 Are you aware that more modern tools exist, such as ltunify (simple) and https://github.com/pwr/Solaar (more advanced)?

[djart01]

I am so sorry, I need it for windows :-( my mistake.

[Lekensteyn]

@djart01 There exist a receiver (yours?) that can only pair to a single device. In order to use it with other devices, you need to unbind (unpair) it first. Anyway, since you are using windows you should try the software provided by Logitech, SetPoint.

[Nephiel]

Once a receiver and a device are paired you don't need Unifying software any more, unless you want to pair to a different device/receiver, or if you want info about battery status.

Didn't know about Solaar. I'll have to check it out if it supports battery info.

[Lekensteyn]

It does support battery information, although the granularity depends on the device. For example, an Anywhere MX can report battery with a precision of 1%, but a M525 mouse can only report "critical" (5%), "low" (20%), "high" (50%) or "full" (90%).

For just battery information, you can also rely on UPower 0.9.22 or later (earlier versions were buggy). Example:

$ upower -d
...
Device: /org/freedesktop/UPower/devices/keyboard_0003o046DoC52Bx001B

    rechargeable:        yes
    state:               discharging
    percentage:          55%
...

(if you know the path, you can also use upower -i /org/freedesktop/UPower/devices/keyboard_0003o046DoC52Bx001B to restrict the output to a single device)

I can also confirm that this works with my M305 mouse and Nano Receiver.

Merged the request, can someone test it out?

Can i Pair Unifying Mouse to pair with non-unifying receiver (non logitech receiver)??

[Lekensteyn]

@RjShadow The radio communication is proprietary, so no, you cannot pair a Unifying mouse with a non-logitech receiver.

[RjShadow]

ow my.. i really need to buy new logitech receiver. :( tnx for the
responce..

how can I open the script at the windows?

[Sharcs]

Above + I have a Logitech MX 620, will it work with the unifying receiver?

[cinchcircuits]

I also have a non unifying receiver.

The device ID for my device was different.

I needed to additionally add a additional nano receiver with the id of 0xc534

#define USB_DEVICE_ID_ALT_NANO_RECEIVER (__s16)0xc534

I was then able to pair with my keyboard and mouse.
