Describe the bug When Logitech K380 is connected (via bluetooth), the CPU hovers around 4% of one logical core. Sometimes, the CPU gets slammed to 100% of one logical core.
I've run solaar -ddd, and the output is a constant stream of something. If I turn the keyboard off, the constant output stops and the CPU usage drops to ~0%. If I turn the keyboard back on, the previous behaviour continues.
The output is here: solaar.log. The jump between 18:14:29 to 18:14:46 is the time the keyboard is off.
