Public bug reported:

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...)
