Title:
  USB 3.0 storage safely remove issue: re-detect (re-plug-in) the
  device(that I have removed already) soon

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a USB 3.0 Hard Disk, a USB 3.0 Flash storage, and a 4GB micro SD with USB 2.0 SD card. When I unmount devices, they still show up when I execute the command. For example, when I plug in my USB 3.0 flash storage to my PC's USB 3.0 port:
  $ df -h
  ...
  /dev/sdc1                     30G   17G   13G   57% /media/chen/MyFlash

  I ummount it and safely remove it, and run df -h, you will see it:
  $ sudo umount /dev/sdc1
  ...
  $ sudo udisks --detach /dev/sdc
  $ df -h
  ...
  /dev/sdc1                     30G   17G   13G   57% /media/chen/MyFlash

  (4)Oops, The issue is an nightmare!!   :( Please see the log )
  $ sudo lspci -vnvn > lspci-vnvn.usbstorage_usb3.0.log

  ========================================================
  The behavior of my USB 3.0 Hard disk is same.

  (1) I plug in my USB 3.0 Hard disk to my pc's USB 3.0 port( the same port ).
  (2) My computer detect my storage soon and automatically mount it.
  $ df -h
  ...
  /dev/sdc1                    932G  205M  932G    1% /media/chen/陈家胜

  (3) I ummount it and safely remove it, and run df -h, you will see it:
  $ sudo umount /dev/sdc1
  [sudo] password for chen:
  ...
  $ sudo udisks --detach /dev/sdc
  $ df -h
  ...
  /dev/sdc1                    932G  205M  932G    1% /media/chen/陈家胜

  (4) :( Please see the log:
  $ sudo lspci -vnvn > lspci-vnvn.usbharddisk_usb3.0.log

  
  (5)And I just realize lspci have no information usb storage, so:
  $ lsusb > lsusb3.0harddisk.log

  (6)I unplug my HD and plug in my storage.
  $ lsusb > lsusb3.0storage.log

  =====================================================================================
  And Have a try that plug in my micro sd card with card reader to USB 3.0 port( the same port ):

  (1) plug in my micro sd card , and :
  $ df -h
  ...
  /dev/sdd4                    3.7G   38M  3.7G    2% /media/chen/DiskGenius
  (2) lsusb:
  $ lsusb 
  ( because i plug in my USB Storage to another usb 3.0 port, so my sd card is /dev/sdd4 )
  ( Why i plug in my USB Storage is that i want get string of "Teclast CoolFlash USB3.0" )
  ( from gnome-disks And I forgot unplug it...)

  (And the led of card reader if off )

  ===================================================================================================
  let's see what happen when I plug in my USB3.0 Flash Storage into USB 2.0 port:

  (1)Plug in USB 3.0 Flash storage into USB 2.0 port

  (The led of FLASH storage is off)

  =================================================
  I have a try again:
  I push in USB 3.0 Flash storage into USB 3.0 Port. I unmount and safely remove it.
  The led of Flash Storage ==> on ==> off =(after 0.7 second)=> on.
  This operation , I won't do it on my Hard Disk......
  and it seem some problems with my hard disk [ASMedia Technology Inc. ASMedia 2105 SATA bridge] between usb 2.0 driver    ;)
