Can't mount any(?) external USB devices/cameras

waynew · 2016-02-16 21:41:55

I've only tried with cameras for sure. I've followed these two guides:

https://wiki.archlinux.org/index.php/Digital_Cameras
https://wiki.archlinux.org/index.php/US … ge_devices

When I ran:

$ loginctl show-session $XDG_SESSION_ID

It showed 'Active=yes' and 'Remote=no', as https://wiki.archlinux.org/index.php/Ge … ermissions says.

However, my digital camera will not mount. I'm also pretty sure that in the past I've tried it with a thumb drive before, to no avail.

This is the device that I'm *currently* looking for.

$ lsusb
...
Bus 002 Device 014: ID 04a9:327f Canon, Inc. EOS Rebel T5 / EOS 1200D / EOS Kiss X70
...

Weird fact #1 - occasionally it disappears from lsusb. And then later it will show up. Or It will only show up if I do `sudo -s` and then lsusb from the root shell.

However, it never shows up when I run `lsblk -f`. Nor does it automount in thunar.

It does appear to be listed in the 40-gphoto.rules file:

⚘ grep 327f /etc/udev/rules.d/40-gphoto.rules                                                                                                                                                                                                        15:31:11
ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="327f", ENV{ID_GPHOTO2}="1", ENV{GPHOTO2_DRIVER}="proprietary", GROUP="camera"

And I'm part of the `camera` group (groups says so)

I think the fact that it disappears may

⚘ dmesg | tail -n 12

That may have something to do with it? The strange thing is that I can plug other devices into the port just fine (keyboard, mouse, wacom tablet).

When I plug in a different Canon camera, it only gives me this in dmesg:

[162435.117161] usb 2-2: new full-speed USB device number 54 using ohci-pci
[162435.300745] usb 2-2: not running at top speed; connect to a high speed hub

Any ideas what I can do to fix this?

For simplicity I'll call the problem camera "camera A" and the other camera "camera B".

I can't help with the automounting or camera-specific issues, but your dmesg output for camera A indicates a hardware issue. Can you isolate the problem to one component? Eg. if camera B works fine with the same cable connected to the same port, this could be a problem with camera A. But it could conceivably be due to quirks in the USB stack, so you should try on another machine and/or with another OS (or maybe just LTS kernel) on this machine.

I've tried with another device - this time a USB flash drive.

Here's the output of dmesg. The first message is when I disconnected it, and everything afterward is after I plugged it back in:

[240583.257536] usb 2-2: USB disconnect, device number 56

It shows up when I `lsusb`, but it doesn't show up under `lsblk -f` (either as normal user *or* root)

Also, I've tried it with multiple different ports on the same computer but still no dice.
