A previously working USB-headset, which has been working flawlessly on Kubuntu
12.04 has ceased to work consistently on 14.04, whenever I try to connect it.
While lsusb lists the device as being present and recognised, the Device
Preference pane in the Audio and Video Settings of KDE keeps displaying the
device in a greyed out state. In other words, it would appear that phonon
thinks the device is still missing. Thus, it cannot be used.
This problem occurs most of the times when I connect the headset to any USB
port, even directly to the motherboard. Only rarely does Phonon wake up to the
returned device.
What I expected to happen was that, after the low-level handshake on the USB
bus, Phonon would pop up a notification that it is switching to the headset
because it´s higher on my preferences. (As it did consistently, prior to the
upgrade from 12.04.)
Instead, there is no announcement whatsoever. Also, the Select Master Channel
window of KMix does not list the headset.
I am running Kubuntu 14.04 LTS.
The package is version 4:4.13.0-0ubuntu1, which is the current package
available from the repositories.
Please note that I am not entirely sure at this time wether kde-runtime is the
correct package.
