This adds a kded module which will monitor Udev's "usb" subsystem for any USB devices being added/removed and emits a notification as a result.
Compared to device notifier, this reacts on any kind of USB device (e.g. mouse, headset), not just storage devices. It also reacts more quickly, for example with an external hard drive, which needs to spin up first before device notifier scans the partitions.
It checks the sysfs removable property to avoid playing a sound
when an internal device that is technically a USB device (e.g.
fingerprint reader, bluetooth adapter, etc) gets enabled/disabled.
This popup is not supposed to be shown by default, it's all about the sound. That's also why I didn't invest a lot of effort into generating a pretty name for the device in question.
TODO:
- We actually need a nice sound for plugging in and unplugging
- Some notification events need to be added to https://invent.kde.org/frameworks/frameworkintegration/-/blob/master/plasma_workspace.notifyrc
