GNOME Bugzilla – Bug 756574
Add support for managing Logitech unifying devices
Last modified: 2021-06-09 16:30:43 UTC
Logitech unifying devices, the tiny USB receiver, work out of the box if you only have a single device to attach to it. Take it out of the box, plug it in, it will expect a new device to try to connect to it, and everything's working. But, if you have a second device, you need to put the receiver in a mode expecting the pairing. Doing so, you can add new devices, you can list paired devices, and you can remove devices, so they won't connect to this received. On the command-line: $ ltunify pair Please turn your wireless device off and on to start pairing. Found new device, id=0x02 Touchpad Dev conn notif is expected to be short, got 0x20 instead Dev conn notif is expected to be short, got 0x20 instead Dev conn notif is expected to be short, got 0x20 instead Dev conn notif is expected to be short, got 0x20 instead $ ltunify list Devices count: 2 Connected devices: idx=1 Keyboard K750 idx=2 Touchpad T650 $ ltunify unpair 2 Unexpected disconnection type 0000 This is very similar to Bluetooth, with all the pairing passwords. ltunify command-line tool: https://lekensteyn.nl/logitech-unifying.html We might be able to slot this in to the new mouse and touchpad designs, as a new section when a Logitech Unifying receiver is available: https://wiki.gnome.org/Design/SystemSettings/Mouse#Tentative_Design
For reference a link to work to create a HID++ library https://github.com/libratbag/libratbag/issues/45
The libratbag issue is now closed, which should make it implementable.
*** Bug 779930 has been marked as a duplicate of this bug. ***
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new bug report at https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/ Thank you for your understanding and your help.
