Currently there is no way to remove a mouse from the list of devices. I have an old mouse that has broke and I replaced with an identical device (other than serial number of course). Both mice still show up in my device list under the mouse settings. This is confusing and I'd like to be able to remove the old mouse/tell settings that it's okay to forget the mouse. However, there's currently no button to do so.
the settings show only connected devices. Unplug your old old device
(In reply to David Redondo from comment #1) > the settings show only connected devices. Unplug your old old device The old device is not plugged in. Unplugging the mouse while in the settings menu disables the drop down. Plugging the mouse back in crashes the settings page. Possibly it's not my old mouse and my mouse is just showing twice...?
That's typically what's happening, yeah.
