kernel 2.6.25-rc2

usb 1-2.2: new full speed USB device using ehci_hcd and address 6
usb 1-2.2: configuration #1 chosen from 1 choice
HID device claimed by neither input, hiddev nor hidraw
input: Logitech Z-10 USB Speaker as
/devices/pci0000:00/0000:00:02.1/usb1/1-2/1-2.2/1-2.2:1.3/input/input4
input: USB HID v1.10 Device [Logitech Z-10 USB Speaker] on
usb-0000:00:02.1-2.2

Nobody claims the device and yet an evdev device shows up in /dev/input? 
That device reports ~8 EV_KEY event codes, which is about right, but 
pressing these buttons doesn't generate any events.
The audio part of the device works ok with the alsa-usb-audio driver.
Though sometimes it locks up, when I try to change the volume of the
speaker through the gnome-volume dialog. When that happens, lsusb
becomes _very_ slow and eventually times out (cannot read device status,
Connection timed out (110)), I also see some of these messages in dmesg:
usb 1-2.2: usbfs: USBDEVFS_CONTROL failed cmd lsusb rqt 128 rq 6 len 255
ret -110 (with different 'len' values). To reset the device I have to
plug it out and in again.

I enabled HID_DEBUG, but no debug messages show up in my dmesg output,
which is strange. Attached is lsusb of the device.
