USB view does not launch

Nautilus shows USB storage just fine. There is no need for an extra application.
What file system is the USB storage using please?
Before you unplug the storage physically, do you use the safe remove feature in your OS(es)?

Thanks

Its usually the NTFS file system that I use in the USB storage. With 16.04 it was a simple "Plug & Play" and "Eject" unmounted the storage which could then be safely (physically) unplugged. Now, with 18.04, I'm not able to do this.

Thanks

You can safe remove in Nautilus.

I suggest you plug the device into a windows system and run a full chkdsk on the file system to make sure it is complete and consistent. NTFS is proprietary to Microsoft and only they know how it works. The NTFS access in Linux is a best effort attempt and having any issues in the file system will cause issues in non-Windows operating systems

For diagnostic purposes, what is the output of the commands (to be executed in a terminal window)

uname -a
lsb_release -crid
apt-cache policy usbview
lsusb

In response to actionparsnip(andrew-woodhead666)

I've plugged the device(s) into a system running on Ubuntu 16.04 and everything is in order, that is, I can view all files/folders and can edit them etc. Also the devices get 'unmounted' using the "safely remove drive" command.

"uname" is a standard function in Ubuntu (in the coreutils package). I am very surprised that you receive "command not found" for the command "uname -a". It seems that you are missing crucial programs.

I tried uname -a again and this is what I got

Linux krishnarajulu-Inspiron-N5010 4.15.0-24-generic #26-Ubuntu SMP Wed Jun 13 08:44:45 UTC 2018 i686 i686 i686 GNU/Linux

I hope this is OK

Ok, it seems to me that the "command not found" was caused by a typo error, and apparently the standard programs are available in your system.

What happens if you open a terminal window and execute the command
usbview

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.

The problem is still not solved. Any device ( pen drive, external hard disk
etc) connected to any of my (working) USB ports does not open. This was not
the case when I was on 16.04

What do you want to express when you say "device does not open"? Open in what sense?

What happens if you execute the command "usbview" in a terminal window?

When the command "usbview" is executed in a terminal window, this is what I get

" cannot open the file /sys/kernel/debug/usb/devices

Verify that you have USB compiled into your kernel, have the USB core modules loaded, and have the usbdevfs filesystem mounted"

When I say that the device does not open, it means that it is not automatically mounted and I can access the "contents"

Is automounting enabled?

What is the output of the command
gsettings list-recursively org.gnome.desktop.media-handling

I dont know if automounting is enabled.

The output of the command is:

krishnarajulu@krishnarajulu-Inspiron-N5010:~$ gsettings list-recursively org.gnome.desktop.media-handling
org.gnome.desktop.media-handling automount-open true
org.gnome.desktop.media-handling automount true
org.gnome.desktop.media-handling autorun-x-content-start-app @as []
org.gnome.desktop.media-handling autorun-never false
org.gnome.desktop.media-handling autorun-x-content-ignore @as []
org.gnome.desktop.media-handling autorun-x-content-open-folder @as []

What happens if you do the following:

If the USB is connected to the system, remove (eject) the USB stick and wait a minute.
Insert the USB stick and wait a minute
Execute the command

dmesg | tail

and copy/paste the output that you receive into this question document.

I did just that and here is the output

krishnarajulu@krishnarajulu-Inspiron-N5010:~$ dmesg | tail

However, when I inserted the USB stick there was no indication that it got "mounted" and I could not get anything
 with a right-click to see the contents of the stick. "Dismounting" was by removing the stick.

The extract of the syslog in your posting shows that within half a minute the device was connected and disconnected twice.
This is not normal and can indicate a hardware problem (either with the stick or with the USB port of the system).

Is the USB stick directly connected, or via some extension cable or hub?

Do you see similar "USB disconnect" messages in the system log if you try plugging the USB stick to a different USB port, and/or do you see the same when using a different stick?

I dont think there is anything wrong with the stick or the USB port(s).
The stick is directly connected/inserted to the USB port.

The syslog showed that the device was connected and disconnected twice because I had (inadvertently)
done just that.

I get similar "USB disconnect" messages in the syslog when the stick is plugged into different USB ports.

I just discovered that any device(stick/external drive) connected to the USB port at start up gets mounted automatically
and its contents can be accessed etc. However, if the device is plugged in after start up then the device cannot be accessed.
I hope this input will be of help in solving this problem

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

my problem persists and i am waiting for a solution

Can you please clearly state what the problem is:

1. What exactly are you doing?
2. What do you expect to happen?
3. What happens instead?

When I plug in a device into the USB port it should get ' mounted'
automatically and I should be able to open and view contents and then '
close and unmount' the device.

This used to happen with Ubuntu 16.04.
I had no such problems then.

Now , with Ubuntu 18.04 , the device gets mounted only if it is plugged in
at startup.

Thanks for your time

What happens if you plug in a USB device, and open nautilus?
On the left hand side you should see a list of links (Recent, Home, ...), with the last one being something like "Other Locations" with a "+" sign to expand.
Is the USB device shown there?
Can you click on it, and does it open?

Sorry for the delay in responding. I was away from my system.

When I click on "Other" , the only thing I see is "Windows Network". The
USB device is NOT shown there.
