Description Mark Fairbairn 2007-12-16 04:19:41 UTC
When plugging USB devices into Opensuse 10.3 the devices are not detected.
In Opensuse 10.2 when plugging in devices they were detected and a window would pop asking what action to take. I do not get this in 10.3

Actions taken - Full complete clean reinstall of 10.3
Reinstall, downgrade and upgrade HAL & D-BUS
Tried installing IVman
If I run fdisk -l with the devices plugged in it shows absolutely nothing has been detected - so they are not even available for a forced mount.

Tried rchal force-reload - nothing happens
It appears that there is also no power being fed to the usb port as batteries in my devices are not recharged when plugged in.

Tried a range of live cds
PCLOS 2007
Simply Mepis 6.5
Ubuntu (one year old distro)
all these live CDs have absolutely no problem in detecting USB devices.
Full clean install of 10.2 - no problem detecting USB devices.

Interestingly the latest Mepis 7.0 RC2 Live CD also does not detect usb devices when plugged in.

Full clean install 10.3 does not detect.

If I plug the usb devices in while the computer is switched off and boot with them plugged in they are detected without problem.

For the output of these commands 
dmesg | grep -i i/o
dmesg | grep usb
lsmod | grep hci

Comment 1 Mark Gordon 2007-12-17 22:52:58 UTC
Do you have a file /usr/share/hal/fdi/policy/gparted-disable-automount.fdi ?
Comment 2 Mark Fairbairn 2007-12-18 05:47:31 UTC
No - no such directory.
I have 

/usr/share/hal/fdi/policy/10osvendor
/usr/share/hal/fdi/policy/20thirdparty

only
Comment 3 Cyril Hrubis 2008-01-03 16:23:32 UTC
As far as usb devices are not being powered it IMHO looks like kernel driver issue.
Comment 4 Oliver Neukum 2008-02-05 10:02:59 UTC
Your devices cannot be configured at the USB level due to -EPROTO. Unfortunately the logs you posted do not show the reason for that error. Can you recompile your kernel with CONFIG_USB_DEBUG? 
Comment 6 Mark Fairbairn 2008-02-05 21:34:57 UTC
How do I do that?
Comment 7 Oliver Neukum 2008-02-06 13:15:27 UTC
Debugging RPMs can be found under:

Comment 8 Mark Fairbairn 2008-02-06 19:02:12 UTC
Thanks - but there only seems to be 64 bit versions available there.
Any idea where I can get a 32 bit version.

Also - once I have this exactly what test shoudl I run - a reapeat of the ones I did previously?
Comment 9 kenneth zadeck 2008-02-07 16:47:06 UTC
When i installed suse 10.3 a few weeks ago on my systems, hotplugging worked on all of my machines.   But sometime after the last two kernel updates in the last week or so hotplugging has stopped working on all of my machines.
Comment 10 Paul Pinault 2008-02-07 23:25:28 UTC
I have the same problem, when I plug an usb camera for exemple, I get this :
usb 3-2: new full speed USB device using uhci_hcd and address 8
usb 3-2: new device found, idVendor=04a9, idProduct=30bb
usb 3-2: new device strings: Mfr=1, Product=2, SerialNumber=0
usb 3-2: Product: Canon Digital Camera
usb 3-2: Manufacturer: Canon Inc.
usb 3-2: configuration #1 chosen from 1 choice

Bug nothing else, peripherical is not mounted :(
I'm in 32b kernel too, no gparted-disable-automount.fdi file

Comment 17 Paul Pinault 2008-02-08 22:33:44 UTC
any way to help you to solve the bug ?!? I can't connect my disk / camera / ipod on my usb .. not fun :( 

tell me what can I do .. if you want me to activate some debug, please precise on what module I wouldn't to recompile all my kernel 
Comment 18 Oliver Neukum 2008-02-11 12:49:34 UTC
@Paul Pinault
Unfortunately in 10.3 activation of USB debugging output requires a recompilation of more or less the whole kernel.
Comment 19 Oliver Neukum 2008-02-11 12:50:46 UTC
Can you please add the entry:

blacklist ehci_hcd

to

/etc/modprobe.d/blacklist

and retry?
Comment 20 kenneth zadeck 2008-02-11 14:28:58 UTC
I did what was suggested in comment #19 on one of my amd64 machines (not my file server) and it made the kde screen which asks what you want to do with the newly plugged in device work for both my usb compact flash card reader and my dvd drive (which is an ata device).  Without adding that line, these devices would never get mounted nor would that screen pop up.

Comment 21 Paul Pinault 2008-02-11 19:52:38 UTC
I try this ... to discover that my problem is different ... 
Usb disk are discovered and associated to device, camera is discovred but not attached to any device.

Kde do not popup any windows on any peripherical and Digicam is not able to find the camera.

Any idea ? should I create a new ticket?

Paul
Comment 22 kenneth zadeck 2008-02-11 19:59:42 UTC
just for completeness: 

when, and only when, i do what comment 19 suggests, digikam is able to find my card and everything is mounted properly. 

also, my problems only stated after one of the last two kernel updates.  Before that everything worked fine.

is there anymore information you need from me?
Comment 23 kenneth zadeck 2008-02-11 20:39:54 UTC
As comment 21 suggests, this may be two separate problems.

I went back and i tried to mount my usb camera on all of my suse10.3 machines.
I have no problems at all on my intel x86-64 (lenovo t60), nor my 2
intel x86-32 machines, a shuttle and ibm t42. 

This problem only occurs on my two amd64 based machines.  While these machines have different motherboards, they are both amd 4400 processors with nvidia chipsets and as i said, your hack in #19 fixes the problem on at least one of these machines (i am more careful with my file server).

I am sorry, i should have tested this before: I just saw that others were having what appeared to be the same problem as myself.  But the amd-64s are my everyday machines and so when i could not get my camera card mounted on these two machines, i just made the incorrect, more broadly based assumption.

Kenny

  

Comment 24 Paul Pinault 2008-02-11 22:08:48 UTC
Problem closed for me too ... /proc/bus/usb was not mounted (but I do not know why). I can access my camera.
Comment 25 kenneth zadeck 2008-02-11 22:44:07 UTC
Oliver, 

I assume from comment #19, that you have some general idea about what is causing my problem.   Is there something else that you want me to try on my machine to narrow the problem further?  I am a gcc developer, not a kernel hacker, so be explicit about anything you need.

Kenny
Comment 26 Mark Fairbairn 2008-02-12 05:43:58 UTC
Thanks - but doesn't seem to have corrected the issue for me.

Added the entry as idrected. Saved and rebooted.
Plugged in usb device.
Disk powers up when plugged as it did before but is not detected by opensuse as a connected device. Power light on the cable goes out.
Comment 27 Oliver Neukum 2008-02-12 08:34:55 UTC
@Paul & Kenneth

Please open separate bug reports. Your problems are different
Comment 28 Oliver Neukum 2008-02-12 08:40:12 UTC
@Mark,

your log is simply blank with regards to hotplug on USB, as if you never had plugged in a device, no signs of failure, simply nothing. Did you verify that the devices you test with work on other computers?
Comment 29 Mark Fairbairn 2008-02-12 09:58:46 UTC
Yes, verified that they work on the same computer with differenct OS.
If I were to do a clean install of Opensuse 10.2 on this very computer now I would not see the issue.
As I mentioned in the original post also
Mepis 6.5 Live CD Hotplug works flawlessly
Mepis 7.0 Live CD shows same symptoms as Opensuse 10.3

This si why I beleive my issue is different to most postings here.
With 10.3 it is simply as if no USB device has been plugged in at all when I plug in after OS as already completed booting.
If I plug devices in before booting they are loaded and work as they should.
Comment 30 Mark Fairbairn 2008-02-12 10:00:28 UTC
Oh - an also verified that devices all work perfectly when plugged into my wife's XP notebook.
Comment 31 Oliver Neukum 2008-02-12 15:33:43 UTC
Is the log from #16 with the kernel from beta.suse.com?
If not, could you please retest?
Comment 32 Mark Fairbairn 2008-02-12 19:59:26 UTC
I used the debug kernel from the 10.3 repo.
The link you provided above is for a 64 bit kernel is it not?
I need a 32 bit kernel.
Comment 33 Mark Fairbairn 2008-02-12 20:00:06 UTC
Oh - I see there is now a 32 bit kernel that wasn't there previously. I'll give it a try in.
Comment 34 Mark Fairbairn 2008-02-14 07:10:07 UTC
New Kernel available in opensuse 10.3 update repo today
2.6.22.17-0.1

Installed and tested - has fixed my problem.
Plug in usb device. Device detected by opensuse and window pops asking what I want to do.
What was in this update that would have corrected the issue?
Haven't had a chance to try the debug kernel that you suggested - do I still need to do this?
Comment 35 Mark Fairbairn 2008-02-16 10:21:52 UTC
hmmmmm . . . ongoing issue.
I swear all I did to correct this problem was to update to the latest available kernel through YAST.
Downgraded to an earlier kernel and no problem detecting usb devices. (??)

Decided to do a full clean vanilla install of 10.3
default kernel on DVD - usb devices not detected on plugin.
Using opensuse updater - update to latest kernel (one that previously corrected my problem) - plug in usb device - not detected. 
What the ....!!!?

So my next move here was to try the debug kernel from beta.suse.com
Downloaded  kernel-debug-2.6.18.8-0.8.i586.rpm

Installed through kpackage

When trying to boot cannot find my harddisk.
Get message "Waiting for device dev/disk/by-id/... to appear"
Asks if I want to go to a fallback position so go "yes"
but still cannot find my disk.
Tried installing through YAST and command line but same problem.
Going back to default kernel problem disappears.

Might need some help on this one.

Comment 37 Christoph Thiel 2008-04-25 15:14:40 UTC

Comment 38 Mark Fairbairn 2008-04-25 22:20:01 UTC
Issue is not resolved.
Not sure what happened with comment 34 but could not replicate correction after clean install of opensuse.
Debug kernel from the repo hasn't shed any light on the issue as per below attachments.
Haven't yet been able to get the debug kernel from above link in comment 7 to work. System won't boot for me with this kernel. Nobody has yet been able to explain why.
Still looking for a resolution but not sure where to go from here.

output of dmesg on a new installation
Comment 42 Manulite Gee 2008-04-30 11:25:30 UTC
I have attached output from my dmesg (with drive plugged in), I'm having exactly the same issue.
I was running openSUSE 10.3 on the same system with updates, the drive was working fine and I backed up my data to it. I decided to repartition and reformat my laptop, and soon after installing 10.3, tried plugging in my drive to copy back my data, and its not even being seen. The LED comes on but that's all.

I noticed though that when booting dbus complains that user gdm not found. I dunno if this has any effect. I'm running KDE with KDM.
Comment 43 Oliver Neukum 2008-05-05 10:35:52 UTC

DMESG from Debug Kernel 2.6.22.18-0.1 (geeko@buildhost) 

Interesting
Updating to this Kernel and rebooting.
Hotplug works just fine.
As you can see near the bottom of the dmesg output - Sony Walkman which was plugged in following boot is detected fine.

I am going to try downgrading to Opensuse default Kernel (non debug) Linux 2.6.22.17-0.1-default and see if things still work following this
Comment 47 Mark Fairbairn 2008-05-10 00:23:57 UTC
OK
Have downgraded to Kernel 2.6.22.17-0.1-default i686
Plugged in device after rebooting and it is detected without problem.
I'm very confused.
Looks as if something in the changing the kernel has corrected the problem. However, isn't the first time I have changed the kernel and it hadn't previously been fixed (other than comment #34).

Waiting to see if it stays fixed (looking forward to upgrade to Opensuse 11 in the near future)

DEMSG with blacklist ehci_hcd removed

OK - seems I have jumped the gun again.
What I didn't notice initially once debug kernel was installed was that my Buffalo/Samsung USB external drive had slowed from full speed (USB ) to very slow transfer speeds (USB 1)
Playing around, found that deleting the entry blacklist ehci_hcd from /etc/modprobe.d/blacklist then rebooting fixed the speed issue with the Buffalo drive, but on plugging in other USB devices I am back where I started with them not being detected.
???

Here is demsg output with the blacklist ehci_hcd removed
Comment 49 Mark Fairbairn 2008-05-10 11:15:28 UTC
Here is a workaround I have stumbled upon
Have removed the entry blacklist ehci_hcd

Boot into 10.3

$sudo modprobe -r ehci_hcd

Insert my usb device which is detected without problem

$sudo modprobe ehci-hcd

Get full speed USB 2.0 access back on all usb devices - including the one I just plugged in and the one that was plugged in at boot

 

Comment 50 Oliver Neukum 2008-05-13 07:48:26 UTC
OK, this is getting confusing.

Can you please provide "lsusb -v" for all devices that you have connected and mark those devices which fail to be properly detected?

lsusb -v number 2
Comment 53 Mark Fairbairn 2008-05-13 11:46:50 UTC
The issue is all devices fail to be properly detected when plugged in unless plugged in prior to booting.
The two lsusb files have exactly the same devices plugged in. The difference between the two is that the first device listed in number 2 (Sony HDD Walkman) is only detected after the modprobe -r ehci_hcd command.
Comment 54 Mark Fairbairn 2008-05-13 11:52:18 UTC
Sorry. Just to clear things up.
Bus 005 Device 003 "Melco Inc" & Bus 001 Device 004 "Lexmark International" were plugged in prior to booting.
Bus 005 Device 004 was plugged into an already loaded OS.
In the first lsusb file you can see it is not present although it is plugged in.
In the second lsusb file you can see it is the first device listed once USB 2.0 has been disabled and then re-enabled.
Comment 55 Oliver Neukum 2008-05-13 15:15:09 UTC
Hi, you'll find a file named "registers" under:

/sys/kernel/debug/ehci/X

where X is a pci id. Please provide
- that file before you plug in a device
- "dmesg -c" at that time
- that file after you plug in a device
- "dmesg" at that time
Comment 56 Mark Fairbairn 2008-05-14 08:29:11 UTC
Don't have any such file or directory as described.

In /sys/kernel/debug 

have two directories

/kprobes & /uhci

Neither of these directories contain such file.

Doing a system search for "registers" file have found one located in

/sys/class/usb_host/usb_host4/

Is this the same thing?

dmesg after plugging device
Comment 61 Mark Fairbairn 2008-05-14 10:38:56 UTC
Not sure if the "registers" file I am dealing with here is the one that you are talking about - but thought worth posting as there are some changes in the file after plugging in my device - although ti still remains unrecognized.

Another point probably worth mentioning . . .
The location of the registers file seems to change location.
I have five directories in
/sys/class/usb_host
they are
/sys/class/usb_host/usb_host1
/sys/class/usb_host/usb_host2
/sys/class/usb_host/usb_host3
/sys/class/usb_host/usb_host4
/sys/class/usb_host/usb_host5

Each time I reboot the "registers" file - while mostly appearing in the fourth directory - on occasion appears in the third directory instead.
It never appears in more than one directory at the same time & I haven't seen it yet appear in anything but the third or fourth directory. (This is following a half dozen reboots)
Of course a longer period of observation might show otherwise.

Comment 62 Oliver Neukum 2008-05-14 12:15:24 UTC
Yes, this is the correct registers file. You'll see only one file because you have only one ehci controller in your computer.

Now to the content. It is interesting. Before plug:

port 1 status 001000 POWER sig=se0
port 2 status 003000 POWER OWNER sig=se0
port 3 status 001005 POWER sig=se0 PE CONNECT
port 4 status 001000 POWER sig=se0
port 5 status 001000 POWER sig=se0
port 6 status 001000 POWER sig=se0
port 7 status 001000 POWER sig=se0
port 8 status 001000 POWER sig=se0
irq normal 243 err 4 reclaim 168 (lost 2)

After plug:

port 1 status 001000 POWER sig=se0
port 2 status 003000 POWER OWNER sig=se0
port 3 status 001005 POWER sig=se0 PE CONNECT
port 4 status 001000 POWER sig=se0
port 5 status 001000 POWER sig=se0
port 6 status 001000 POWER sig=se0
port 7 status 001803 POWER sig=j CSC CONNECT
port 8 status 001000 POWER sig=se0
irq normal 243 err 4 reclaim 168 (lost 2)

Port 7 has changed. A low speed device has been
detected, but CSC (Connect Status Change) is still
set. Normally this indicates that the event has not
been processed and should happen only very briefly.
Khubd is supposed to clear this and handle the event.
Comment 63 Oliver Neukum 2008-05-14 12:26:33 UTC
Ok,

1. - khubd may be stuck -> please attach the output of "ps aux"
2. - interrupt delivery may be bad -> please attach the output of "cat /proc/interrupts"

Doing system wide search there is no such file as "registers" located anywhere on my system.
Has the name of the file changed for Opensuse 11.0?
Using KDE4 by the way.

Comment 75 Oliver Neukum 2008-07-04 15:08:21 UTC
You need to install the kernel-debug kernel.
Comment 76 Mark Fairbairn 2008-07-04 23:13:38 UTC
Debug kernel is installed.
Tried reinstalling debug kernel.
Still no registers file located anywhere on computer.

Have done a complete reinstall of Opensuse 11 form DVD with debug kernel and can still not locate any "registers" file anywhere on computer.

Are we sure this file should exist in 11.0?
Comment 78 Oliver Neukum 2008-07-11 08:00:16 UTC
It is supposed to exist when the debug kernel is installed. If not, that's a bug.

That explains it. I'll fix it and compile a kernel with the fix.

Debugging kernels that fix the problem can be found under:

Comment 83 Mark Fairbairn 2008-07-21 09:03:56 UTC
Interesting . . . 
Installed your Kernel.
Registers file is located
/sys/kernel/debug/ehci/0000:00:1d.7

It is a completely empty file (0 bytes)
Plug in device there is no change - still completely empty.

run

modprobe -r ehci_hcd
modprobe ehci-hcd

device now loaded but registers is still a completely empty file.

Comment 85 Oliver Neukum 2008-07-21 19:03:37 UTC
Please try the new kernel at the same place.
Comment 86 Mark Fairbairn 2008-07-25 08:52:11 UTC
Installed the latest kernel you provided
Linux 2.6.25.11-0.1-debug i686

exactly the same situation as the previous kernel. At each of the three stages noted in previous comment the "registers" file remains unchanged (a completely empty file 0 bytes)

Comment 87 Oliver Neukum 2008-07-25 08:59:46 UTC
Odd, very odd. I am investigating.
Comment 88 Oliver Neukum 2008-07-25 09:00:32 UTC
I misclicked.
Comment 89 Oliver Neukum 2008-07-28 08:29:31 UTC
Just to make sure this actually sane, please provide the output of "cat /proc/config.gz" with the last kernel i provided. This needs double checking.

output from cat /proc/config.gz
Comment 91 Oliver Neukum 2008-08-01 12:04:12 UTC
Inexplicable. Anyway, as this approach will probably not work, please attach with the debug kernel "dmesg -c" before you plug in a device that is not detected and "dmesg -c" after plugging it in.

dmesg -c before inserting device

dmesg -c immediately after booting

dmesg -c after inserting device

after inserting pendrive - nothing detected

dmesg -c after modprobe

also supplying this dmesg -c following modprobe with device now detected (not sure if this one is useful or not)
Comment 95 Oliver Neukum 2008-08-02 13:05:59 UTC
That shows that the interrupt is lost. Why it is lost could be learned from the register file.
Comment 96 Oliver Neukum 2008-08-04 13:25:56 UTC
Please provide the output of "cat /proc/interrupts"

Comment 98 Oliver Neukum 2008-08-15 09:45:03 UTC
These are exactly the same symptoms of the bug this bug was originally considered a duplicate of
Comment 99 Mark Fairbairn 2008-08-15 11:27:04 UTC
Perhaps same symptoms but bug is unresolved for me.
Comment 100 Oliver Neukum 2008-08-18 07:11:26 UTC
This needs the register file. I'll recheck the debug kernels.
Comment 101 Oliver Neukum 2008-09-11 08:47:18 UTC
Without the register file this is undebuggable.
Comment 102 Mark Fairbairn 2008-09-11 11:25:30 UTC
so what would my next step be here?
How can I get this issue resolved?
Comment 103 Mark Fairbairn 2008-09-12 23:53:16 UTC
should I open a new bug?
Enter a bug for the registers file?
Comment 104 Oliver Neukum 2008-09-24 12:48:30 UTC
Yes, do so.
