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...)
