[Virtual-pkg-base-maintainers] Bug#727240: base: pressing multimedia key on "Genius GX Gaming Manticore" freezes keyboard

[Ondrej]

Package: base
Severity: normal

Dear Maintainer,
after connecting my new keyboard Genius GX Gaming Manticore, I am unable to use multimedia keys (play/pause, mute, volume up/down). After pressing some of these keys, keyboard "freezes" and I am unable to do anything. Only solution I've found is replugging keyboard into USB port.
After snooping USB "traffic" (using wireshark), there are no data sent, when I press these keys. But when I tunnel keyboard to virtualized Windows XP in Virtualbox, after pressing these keys, I see some data flowing.
