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:
Expired
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...)

(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 ;)
WORKAROUND: In BIOS > Settings > Advanced > USB Configuration change
"XHCI Hand-off" to [Disabled].
