[Kde-hardware-devel] Not receiving Solid::DeviceNotifier deviceRemoved() SIGNAL

[Alex Fiestas]

The couse of the problem is that udev is changing the parent when the 
device is disconnected to the last parent that still exists, example:

The parent of: 		../usb5/5-1/5-1:1.0/sound/card1/pcmC1D0c
was: 			../usb5/5-1/5-1:1.0/sound/card1
but when removed: 	../usb5/

We're checking if the parent subsystem is "sound" because we don't want 
root devices to show up since they are useles...

Let's see what we can do to fix this behavior.
