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

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have an USB 3.0 Hard Disk and  an USB 3.0 Flash storage.
  And I have an 4GB micro sd with USB 2.0 sd card. But I do not have 2.0 USB storage or 2.0 usb hard disk.

  OK, let me describe this issue:

  (1) I plug in my USB 3.0 flash storage to my pc's USB 3.0 port.
  (2) My computer detect my storage soon and automatically mount it.
  $ df -h
  ...
  /dev/sdc1                     30G   17G   13G   57% /media/chen/MyFlash

  (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                     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

  #It's so strange that lsusb show my usb storage "Kingston Technology Company Inc.", But
  #my usb storage is "Teclast CoolFlash USB3.0". OK, that may not be important.

  
  =====================================================================================
  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...)
