Wm: muffin dm: LightDM Distro: Linux Mint 20 Ulyana base: Ubuntu 20.04 focal Thanks in advance for any help or suggestions you can offer. Everything else works except the Logitech. I tried every port on the laptop, the dock, and external USB hubs. I tried different Logitech receivers and they do not work either. The current mouse/keyboard set-up has been in use without change for several years. I removed Solaar and reinstalled, with no effect.Īs far as I can tell, all other USB devices (thumb drives, hard drives, phone, keyboard, mouse) all work fine. Now Solaar tells me that there are no receivers found. I used Solaar to unpair and pair the devices, no change. I found no pattern (yet) to reproduce the problem. If I unplugged the receiver and plugged it back in, it would start working again but stop a bit later. I first noticed that the mouse & keyboard stopped responding in the middle of a session. I used Timeshift to go back and the issue still remains. I think it started after the last kernel update. My Logitech devices (M510 & K520) stopped working.
