Dear Maintainer,

dmesg reports devices when plugged in.  Shotwell sees USB devices.
Thunar does not see USB or eSATA devices.

Hi,

is udisks2 installed?

Regards,

Apparently not.

Ah, sorry, missed you're on stable :) Please check for udisks package
then.

I did some more testing with a Canon PowerShot A570IS camera (USB
interface) just now:

1.  (Xfce XMouse?) -> Settings -> Removable Drives and Media -> Storage
-> Removable Storage -> all boxes unchecked.

2.  Open Thunar and Shotwell.

2.  Plug in Canon PowerShot A570IS camera via USB.  Camera does not
change to USB connected state.  No desktop icon.  Nothing in Thunar.
However, an entry appears for the camera in the left pane of Shotwell.

3.  Select camera in Shotwell.  Camera goes to USB connected state.
Shotwell accesses camera and displays thumbnails in right pane.  Nothing
on desktop.  Nothing in Thunar.


Therefore, something is broken for the Xfce desktop and Thunar -- I
expected a camera icon on the desktop and a camera entry in the left
pane of Thunar at steps #2 and #3.  Shotwell seems okay.


I also did some testing with two different USB flash drives and obtained
the same results:

1.  (Xfce Mouse?) -> Settings -> Removable Drives and Media -> Storage
-> Removable Storage -> all boxes unchecked.

2.  Open Thunar.

3.  Plug in USB flash drive.  Drive icon appears on desktop.  Drive
entry appears in left pane of Thunar.

4.  Desktop icon context menu has option to mount drive; don't invoke it.

5.  Select drive in left pane of Thunar.  Drive contents displayed in
right pane.

6.  Desktop icon context menu on desktop now has option to eject drive.


Therefore, everything seems to be working correctly with Xfce and Thunar
for USB flash drives.


I also did some testing on another Wheezy/Xfce machine with a Seagate
FreeAgent Xtreme external hard disk drive via USB and eSATA -- nothing
on desktop or in Thunar.


Therefore, it seems that whatever Xfce/ Debian/ Linux subsystem
underlies Thunar works for USB flash drives, but not for the camera or
for the external hard disk drive.


Another clue -- hot-plug for the external hard drive stoppled working
around Sept. 3, when I did a BIOS update.  I seem to recall a kernel
update around the same time.


David

Actually, that's not a good test. Thunar only supports/shows USB Mass
Storage devices, which Canon cameras are not (they use some proprietary
canon protocol on USB mode, or PTP on PTP mode). You need to interface
with it using gphoto2, which is what Shotwell is actually doing.

Indeed.

This one is weird.

Can you check:

- if the USB drive is correctly seen by the kernel (shows in dmesg, can
be mounted manually)
- if the USB drive is correctly seen by udisks (I think it's someting
like udisks --dump, and udisks --monitor can help too).

Regards,

I assume the explanation also applies to the Xfce desktop (?).


It would be nice if Xfce and Thunar supported Canon cameras.  We have
several, and I'm migrating our SOHO desktops to debian-7.2-i386-xfce.
Debian 7 installations:

1.  Intel D945GNT motherboard with fairly recent and lightly used
install of Debian 7 amd64 (system used for initial bug report) --
hotplug works correctly via both USB and Firewire.  (Machine does not
have eSATA port.)  This doesn't match my earlier findings.  I don't know
why.

2.  Intel D945GNT motherboard with fresh install (yesterday and today)
of Debian 7 i386 -- hotplug works correctly via both USB and Firewire.

3.  Intel DQ67SWB3 motherboard with older (December 2012, possibly
pre-Stable?) and heavily used install of Debian 7 amd64 -- hotplug works
correctly for USB, but fails for eSATA.

a.  Here are the diffs after the USB hotplug:

c.  Here are the diffs after eSATA hotplug:

2013-10-29 21:07:45 dpchrist@p43200 ~/Data/dpchrist/bugs/debian/728065
$ diff 12-after-disconnecting-usb/dmesg.out
13-after-hotplug-esata/dmesg.out

2013-10-29 21:07:51 dpchrist@p43200 ~/Data/dpchrist/bugs/debian/728065
$ diff 12-after-disconnecting-usb/udisks--dump.out
13-after-hotplug-esata/udisks--dump.out


So, it appears that the kernel is not seeing eSATA hotplug events (?).


I am in the process of preparing to wipe and rebuild the machine having
the eSATA problems.  I'll report when I have more information.

Yes.

Afaik that's not possible on Wheezy.

On Jessie+, iirc, gphoto devices should appear in Thunar once they are
gio/gvfs-mounted, that has to be done manually or in thunar-volman (and
it's broken right now because of

The diffs are not really readable, but if the kernel doesn't see the
hotplug events, there's not much chance anything userland can do
anything, so it looks more like a kernel issue. It might help to try
with a more recent kernel (I assume you're using a stock Debian
kernel?).
Ok.

Whenever I start using backports, using CPAN, hand compiling software,
etc., my systems start breaking.  So, I try to stick with stock Debian
Stable as much as possible.


David

Indeed, it was just a matter of testing a more recent kernel, than
reverting.

USB hotplug is working.


eSATA hotplug is not working.  See console session, below.


External drive works if connected when system is booted.
