   ACTION!="add|change", GOTO="xorg_plantronics_end"
   KERNEL!="event*", GOTO="xorg_plantronics_end"
    
   SUBSYSTEMS=="usb", ENV{ID_BUS}=="", IMPORT{builtin}="usb_id"
    
   ENV{ID_VENDOR_ID}=="047f", ENV{ID_MODEL_ID}=="c013", ENV{ID_INPUT_KEY}="1", ENV{ID_INPUT_KEYBOARD}="1"
    
   LABEL="xorg_plantronics_end"

2. Create file /etc/udev/hwdb.d/60-keyboard.hwdb with the following content:

   # Plantronics .Audio 648 USB
