    This will send for a card reader slot (remove/add media):
      UEVENT[1187091572.155884] change   /devices/pci0000:00/0000:00:1d.7/usb5/5-2/5-2:1.0/host7/target7:0:0/7:0:0:0 (scsi)
      UEVENT[1187091572.162314] remove   /block/sdb/sdb1 (block)
      UEVENT[1187091572.172464] add      /block/sdb/sdb1 (block)
      UEVENT[1187091572.175408] change   /devices/pci0000:00/0000:00:1d.7/usb5/5-2/5-2:1.0/host7/target7:0:0/7:0:0:0 (scsi)
    
    and for a DVD drive (add/eject media):
      UEVENT[1187091590.189159] change   /devices/pci0000:00/0000:00:1f.1/host4/target4:0:0/4:0:0:0 (scsi)
      UEVENT[1187091590.957124] add      /module/isofs (module)
      UEVENT[1187091604.468207] change   /devices/pci0000:00/0000:00:1f.1/host4/target4:0:0/4:0:0:0 (scsi)
    
    Userspace gets events, even for unpartitioned media. This unifies
    the event handling for asynchronoous events (AN) and events caused by
    perodical polling the device from userspace.
