Plamsa5 Disk and Devices, USB stick detected first plugin only.

chrisretusn · 06-16-2021, 07:34 AM

Slackware64-current, Wed Jun 16 01:06:18 UTC 2021 ChangeLog.txt, running KDE Plasma. Noticed this behavior after the after the Sun Jun 13 19:27:08 UTC 2021 or perhaps the Thu Jun 10 23:42:12 UTC 2021 update.

SanDisk USB inserted, Disk and Devices detects it, presents options to Mount and Open, Download images using gweview or digikam, Mount.

Note: code blocks are from /var/log/messages.

Code:

I use the Mount option. I am able to access it via /run/media/chris/87E3-2C37/ no issues. I can also open with Dolphin and navigate not issues.

Use Safely remove, device is removed from Disk and Devices:

Code:

Jun 16 19:36:46 racermach kernel: usb 1-2: USB disconnect, device number 10

Remove the USB from the port, messages log entry nothing. Expected this.

Plug the same USB in the same port. Disk and Devices does not detect it.

Code:

Remove the USB from port:

Code:

Jun 16 19:41:31 racermach kernel: usb 1-2: USB disconnect, device number 11

Note: This happens no matter which USB port I use, same result.

Now, take a different USB (PNY) and plug it in. THis USB is detected by Disk and Devices. I can mount, browse it with Dolphin.

Code:

Jun 16 19:44:08 racermach kernel: usb 1-2: new high-speed USB device number 14 using ehci-pci

On mounting PNY device:

Code:

On Safely remove:

Code:

On Unpluging device:

Code:

Jun 16 20:05:56 racermach kernel: usb 1-2: USB disconnect, device number 16

I now plug in the previous USB (SanDisk) device, it now detected by Disk and Devices

Code:

 Jun 16 19:45:53 racermach kernel: usb 1-2: new high-speed USB device number 15 using ehci-pci

Jun 16 19:45:56 racermach dbus-daemon[1027]: [system] Successfully activated service 'org.kde.kded.smart'

In summary the USB is only recognized by Disk and Devices on first plugin, plugging the same USB in subsequent times after that and Disk and Devices does not detect it.

Using another USB stick, then going back to the other stick then it is detected.

I discovered that Dolphin picks the device up when reinserted and mounts it correctly when the stick is selected. So I can use Dolphin as a workaround to mount the USB stick.

I anyone else seeing this problem and how to fix it.

business_kid · 06-16-2021, 11:40 AM

I Would prefer to see the output directly from the kernel. Plug in, and run

Code:

[sudo] dmesg |tail

Ditto for plugging out.

On my system using Slackware64-Current & XFCE4, the drive letter is recycled very quickly (seconds), but I have no automount daemon - the KISS principle. My guess is that's where the long memory is coming from. Of course, in cases like these, one man's 'feature' is another man's 'bug.'

Try in /proc/mounts & /etc/mtab

Code:

cat /etc/mtab |grep sdc

As I mentioned in my first post, this is a new behavior, I will modify this to possibly since Wed Jun 9 18:59:30 UTC 2021 ChangeLog.txt. Reasoning on my laptop I was denied access to mount the USB, this behavior was fixed with the Wed Jun 16 01:06:18 UTC 2021 update with I presume "kde/polkit-kde-agent-1-5.22.1-x86_64-1.txz: Upgraded."

'cat /etc/mtab |grep sdc' produces nothing, unless... The mount is accepted by "Disk & Devices" or I mount the device by selecting it using Dolphin which produces this:

Code:

 cat /etc/mtab | grep sdc
/dev/sdc1 /run/media/chris/B453-E58A vfat rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0

chrisretusn · 06-17-2021, 04:28 AM

Forgot to add this:

Code:

cat /proc/mounts | grep sdc
/dev/sdc1 /run/media/chris/B453-E58A vfat rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0
/dev/sdc1 /var/run/media/chris/B453-E58A vfat rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0

Gone as soon as drive unmounted, so there is no persistence.

This USB does not trigger Disk & Devices even after seven hours hours. Unplugged around 10am plugged back in just a few minutes ago, 5:30pm

business_kid · 06-17-2021, 04:56 AM

So it's clear. The kernel is dropping it, 'disks & devices' isn't.

Then, it's a kde issue. You may be able to configure your way out of it in Disks & Devices, but my pc crawls under kde, as if every program is a bash script

I wish you luck. There may already be a cug about it, or you could file one.

chrisretusn · 06-17-2021, 05:22 AM

Here KDE is a bit slower than I'd like on starting (startx) and closing (logging out), especially after a reboot. I do have six programs set for autostart though. Once running it's a-okay.

How is it clear the kernel is dropping it?

I didn't mention above, that a reboot clears up the issue until the USB is plugged in a second time; which of course makes sense.

business_kid · 06-17-2021, 01:01 PM

/proc/mounts is the kernel record, which clears as soon as the disk is cleared.

Disks & Devices might simply have a bigger log of attached devices to reassign them the letter they had before. I just don't know.

bitfuzzy · 06-17-2021, 01:35 PM

I've verified this as well with a kingston datatraveler and Sandisk Cruiser... Weird as hell

Test 1 - Both connected and seen by "Disks & Devices"

Both mounted and unmounted via Dolphin (my usual mounting method) and disconnected

Test 2 - Both reconnected and seen by "Disks & Devices"

Kingston mounted and unmounted via "Disks & Devices" and disconnected
Sandisk mounted and unmounted via Dolphin and disconnected

Test 3 - Both reconnected

Sandisk seen by "Disks & Devices"
Kingston not seen

Both mountable and usable under Dolphin

I'm wondering if this could be another bug related to libusb?

Regnad Kcin · 06-17-2021, 09:51 PM

Yes I have this error going also just as chrisretusn describes.
EDIT:
It is not fixed by the latest update to current (Wed Jun 16 18:32:47 UTC 2021)

chrisretusn · 06-19-2021, 08:00 AM

I boot to runlevel 3, I found that logging out of KDE back to the CLI clears what ever is causing this. I can startx back in to KDE and on the USB stick is recognized. I have not tried this with runlevel 4.

Edit: Just verified same behavior with runlevel 4 (Plamsa X11).

business_kid · 06-19-2021, 11:07 AM

Ah well, then, it's the familiar problem of the Window Manager thinking it knows what you want better than you do. We've all had that fight sometime. Enjoy!

Regnad Kcin · 06-21-2021, 09:13 PM

This seems to be fixed with the recent updates to -current as of 22Jun2021

chrisretusn · 06-22-2021, 05:14 AM

Not fixed here. As of ChangeLog.txt Mon Jun 21 18:26:35 UTC 2021; which is the latest as show at http://www.slackware.com/changelog/c...php?cpu=x86_64

Tested with five different USB sticks.

Tonus · 06-22-2021, 09:11 AM

Could it be related to power saving options in bios or whatever ?

I can't see how these could be related. The USB sticks mount just fine using Dolphin. If you open System Settings > Removable Storage > Removable Devices you can watch these devices show as Disconnect or Attached devices. I'm still playing around with this so far it is not working as I think it should.

I believe the problem lies in systemsettings kcm_deviceautomounter.
