Hi,

I have a set of USB speakers which also implement HID:

According to the Usage Page the device is not a keyboard, yet the keyboard handler
binds. Is this really sensible?
I: Bus=0003 Vendor=0471 Product=0104 Version=0100
N: Name="Philips Electronics Philips USB Digital Speaker System"
P: Phys=usb-0000:00:1d.0-1/input2
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb6/6-1/6-1:1.2/input/input15
U: Uniq=
H: Handlers=kbd event11 
B: PROP=0
B: EV=13
B: KEY=e000000000000 0
B: MSC=10

As long as it's not the only thing that binds. We're just missing udev
level information to be able to match the audio device and the sound
device, so that pressing the buttons would change the volume on that
device. See:
https://bugzilla.gnome.org/show_bug.cgi?id=340720

Well then it would seem than binding to only an event interface should
make things easier for X.
