USB ports: connect-debounce failed, port disabled

[sengo]

Binary package hint: linux-image-2.6.20-9-generic

I recently installed feisty on a Fujitsu Siemens Amilo pro v3205. Even during installation my console was flooded with hundreds of:

[ ???.??????] hub 5-0:1.0: connect-debounce failed, port 6 disabled

The problem didn't go away after installation and logs got flooded with the message too:

cristian@alastor:~$ grep debounce /var/log/syslog|wc -l
1621

After some googling I discovered this is probably caused by the onboard usb bluetooth receveir: if I disable then re-enable it with the keyboard switch the message goes away. If I boot the laptop with BT disabled, then I enable it the message doesn't appear at all in the kernel logs.
Everything was fine on the same hardware with 2.6.17 on edgy.

[Cristian Aravena Romero (caravena)]

Thanks for taking the time to report this bug. Unfortunately we can't fix it, because your description doesn't yet have enough information.

Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/DebuggingKernelProblems . Thanks in advance!

I tried building a 2.6.19 vanilla kernel and the problem is still there, then I rebuilt linux-sources-2.6.20 enabling usb debug.
Additional logs attached.

[Marco (mfj)]

I have same notebook and same problems with every kernel version 2.6.20.x.
I tried to compile last stable vanilla kernel (2.6.20.3) without success.
No problem with version 2.6.17.x

[Marco (mfj)]

Last kernel update don't resolve this bug:
I tried again to recompile the source, adding the option CONFIG_USB_SUSPEND=y present in previous versions, and removing the APM/ACPI support.

at least I'm not alone, I also reported this on the linux-usb-devel mailing list:

http://<email address hidden>/msg51408.html
and
http://bugzilla.kernel.org/show_bug.cgi?id=8104

Happy hacking.

[Ben Collins (ben-collins)]

Confirmed bugs should have their Importance set.

[Cosmin Saveanu (csaveanu)]

I can confirm this annoying error message that appeared on my Fujitsu-Siemens Amilo Si1520 after upgrading to Feisty and the 2.6.20-15 kernel. I hope someone will find a solution. On an ArchLinux wiki a workaround is indicated (http://wiki.archlinux.org/index.php/Fujitsu-Siemens_Amilo_Pro_V3205):

"
A hub error message is printed repeatedly:

hub 1-0:1.0: connect-debounce failed, port 6 disabled

A workaround is to disable the laptop's wi-fi device in BIOS.
"
I have no idea how one can disable the wi-fi in BIOS and if, in that case, one can start it after the boot (?). However I observed that the messages stopped after switching off and on the wi-fi button. Thank you, Cosmin

[Marco (mfj)]

I don't know your specific laptop, but with a Amilo Pro V3205 to bypass this bug, is enough switching off - on the bluetooth button (Fn- Esc).
If I don't perform this necessary operation during the boot, I'll have bluetooth interface unrecognized.

[Cosmin Saveanu (csaveanu)]

Just in case it might give someone an idea about the bug, I've copied the dmesg output before and after siwtching on-off the bluetooth/wi-fi button. Indeed, that will stop the 'ugly' connect-debounce message.

I have the same problem on my ThinkPad T42 2373-Y9H... recently after upgrading to Feisty. Removing stopping bluetooth service and removing bluetooth modules (bluetooth, rfcomm, l2cap) doesn't help. I can't try the "stop wifi" workaround because I actually use wifi to connect to the Internet.

Description of the notebook can be found at: http://www-307.ibm.com/pc/support/site.wss/product.do?subcategoryind=0&familyind=171864&brandind=10&doccategoryind=0&modelind=198847&doctypeind=2&validate=true&partnumberind=0&sitestyle=lenovo&template=%2Fproductpage%2Flandingpages%2FproductPageLandingPage.vm&operatingsystemind=49979&machineind=171874

The requested information is attached (in one file, separated off by line of dashes).

[Cosmin Saveanu (csaveanu)]

Hi fraktalek,

It looks like switching off and then on the wifi can solve (temporarily) the problem. It means that at the end the wifi connection is on, I'm sorry I was not very clear in my previous post. Please take a look at your dmesg output before and after doing the switching on and off for the wifi. I also use wifi for my Internet connection.

Cosmin

[jkbkot (jkbkot)]

I'm sorry, my problem I reported in previous comment isn't related to this bug... I found it to be a faulty mouse. So feel free to delete these two comments if you can.

I have found the resolution for this bug (for my configuration: Fujitsu-Siemens Amilo Pro v3205).

1) Update your bios firmware to last release avaiable.
2) In bios setup -> advanced tab -> disable the usb bios legacy support (sometimes the flashing procedure sets this option as enabled)
3) Restart

With this procedure, bluetooth module is recognized during the boot without connect debounce error of usb hub

[sengo (sengo)]

Hello Marco, I have an Amilo Pro v3205 too, but your trick doesn't work for me: I upgraded to the last bios available (1.20) booting from the iso, loaded bios defaults and disabled usb legacy support... No way, connect debounce still there ://

[Marco (mfj)]

It's curious... This is my bios configuration (v. 1.20):

Advanced -> Internal Devices Configuration -> all options ENABLED
Advanced -> USB BIOS Legacy Support: DISABLED
Advanced -> ATA Control Mode: ENHANCED, AHCI Configuration: ENABLED

My kernel is 2.6.20-15-generic. Before try this changes, I have compiled a vanilla kernel 2.6.21.1 but the problem still stayed.

[ehamberg (hamberg)]

I also tried upgrading to the newest BIOS version and disabling USB BIOS legacy support without luck.

[Marco (mfj)]

After last kernel updating (from 2.6.20-15 to 2.6.20-16) I report again this problem... Now if I launch old kernel from grub the result don't change.

[Jamie Lokier (jamie-shareable)]

I'd just like to add myself to the list of voices confirming the problem. I have a Fujitsu-Siemens Amilo Si-1520 laptop, like Cosmin Saveunu, and these messages appear at boot if wireless is enabled. Disabling wireless, and re-enabling, makes them go away. So does booting with wireless disabled. There's no BIOS option to disable it, just having it disabled at the last shutdown is the way to have it disabled at the next boot.

Powertop suggests this is contributing to the number of USB-related IRQ wakeups, draining (a little) power.

[Marco (mfj)]

Has someone tested vanilla kernel 2.6.22-rc4? Where is the solution to this bug (kernel or other packages)?

[Tom Jennings (tomj-wps)]

I too get this since the 2.6.20 kernel with ubuntu 7.04

/connect-debounce... port 1 disabled/

My hardware is an old VIA EPIA5000 card (in my car computer) with an EXTERNAL USB hub, to which is attached a custom music control head (FTDI serial device). Userland code (perl) detaches/reattaches the USB device upon read or write error. Computer is embedded and headless.

Unplugging/replugging the USB device usually, but not always, triggers the /connect-debounce... port 1 disabled/ error. The code is awaiting the existence if /dev/ttyUSB0 after which it attempts to open.

This all ran fine for most of a year with 6.10 (was that 2.6.16 kernel? I forget).

[Marco (mfj)]

After many tests, I can confirm that this bug affects ALL Distros with Kernel 2.6.17-12 or upper.

From Alan Stern (Kernel Development):

Some other experiments to try with a "working" kernel and Bluetooth enabled:
rmmod uhci-hcd and modprobe it back. Do the same with ehci-hcd. Unload both
of them and then modprobe them back in one order or the other. Maybe it will
turn out that the so-called "working" kernel doesn't always work.

[Marco (mfj)]

After few days of "no flooding", I have again same problem with Ubuntu 7.10 RC and Final Release (both in Live mode). I don't know if this problem depends from kernel or other components.

Alan Stern (Kernel Developer) says: "Note that it's entirely possible that the problem is triggered not by the
kernel but by some other part of your distribution (like an initramfs image).".
Any ideas?

[Benjamin Drung (bdrung)]

I am using a fresh install of Ubuntu 7.10 amd64. The bug is still present, but it changes it behavior.

After starting Ubuntu the bug floods the console. But after some time the flooding disappears and the Bluetooth Applet appears in the panel. I have no idea which component cause the change, but I thing it is connected with the network. Mostly the flooding disappears when I get a wlan connection or plug in the network cable.

This will be retargeted towards the Hardy kernel once it is released. I've tagged this as "hardy-kernel-candidate" so that we make sure to retarget this report once the new release is out. However against the linux-source-2.6.22 package this is being marked as "Won't Fix" as it does not meet the criteria for a stable release update.

That's bullshit. This bug causes wireless connections (both WLAN and Bluetooth) to not work for effected users. That is very much a "severe regression" that qualifies for an update according to https://wiki.ubuntu.com/StableReleaseUpdates. Plus there is no point in wontfixing something until we figure out how it could be fixed.

[Leann Ogasawara (leannogasawara)]

The Hardy Heron kernel was recently uploaded for testing. We'd really appreciate it if you could try testing with this newer kernel and verify if this issue still exists. Unfortunately, the Hardy Heron Alpha1 LiveCD was released with the older 2.6.22 kernel. You'll have to manually install the newer Hardy Heron kernel in order to test. This should not be the case for Alpha2. However, here are the instructions to install (if you choose to do so):

1) edit the file /etc/apt/sources.list and add the following line:

deb http://archive.ubuntu.com/ubuntu hardy main restricted

2) sudo apt-get update
3) sudo apt-get install linux-image-2.6.24-1-generic
4) reboot and select the new kernel from the grub menu

After you've tested, please feel free to revert back - ie boot into the old kernel, sudo apt-get remove linux-image-2.6.24-1-generic, and remove the line from /etc/apt/sources.list . Please update this report with your results. Thanks in advance!

[kimbledon (kimbledon)]

You talked about the bios firmware update. Where can I find that bootable .iso file?

[kimbledon (kimbledon)]

Found it from fujitsu-siemens support page.

[Leann Ogasawara (leannogasawara)]

The Hardy Heron Alpha series was recently released. Alpha2 and subsequent releases contain an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ .

[Benjamin Drung (bdrung)]

I tested the current (2008-01-21) live cd from http://cdimage.ubuntu.com/daily-live/ . dmesg reportet no debounce failure. WLAN and Bluetooth are identified correct. So I think the problem is solved for my notebook. From time to time I will check if the debounce failure will come back.

I'm having the same problem on a Sony PCG-Z600LEK. I cant even boot. I seem to recall being able to use 7.10 fine, but the message was always flooding the message log (and using the tty was impossible). I cannot install 8.4 - it hangs on the boot screen for a while, then drops to tty and floods it with debounce messages.

Im having the same issue with Mint (naturally since it's ubuntu based). I also have the problem with the latest Debian (although i installed just fine, but the system went down after an update - so it's probably kernel related). I'm going to try non debian distros like Fedora but i expect the same. I will also try using older versions although this bug is reported across multiple kernels and has cropped up in the past.

Im also getting:

usb 1-1.3: device not accepting address xx, error -71

and

device descriptor read/64, error -71.

I have no bluetooth in this laptop, have no usb devices attached and i have even tried opening it up and manually disconnecting the usb ports from the motherboard (so it's controller related) and the issue still remains. All the stuff about legacy etc... is useless as are all the kernel parameters. As of right now this laptop is a paperweight until this issue is resolved.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

This is on my desktop (not a laptop, and no wireless).

One more piece of data: this bug is more than just spewing an error into the logs.

When I connect an iPhone to a USB port for overnight battery charging, and this bug hits - it effectively disables the charging. Result: in the morning the battery is totally consumed. Apparently, when the port is disabled, it causes a overnight current drain i.e. recharging turns into discharging.

[Amit Kucheria (amitk)]

Ariel: There have been several changes to the core USB subsystem in 2.6.28. Would it be possible for you to test if the bug still exists with a Jaunty 9.04 Beta? Refer to http://www.ubuntu.com/testing/jaunty/beta . Please let us know.

[Amit Kucheria (amitk)]

2.6.22 is a very old kernel. It is unlikely that a fix will be backported to it.

[Amit Kucheria (amitk)]

Marking as Incomplete and awaiting feedback on Jaunty. Since this is very specific to certain peripherals/hubs it is also important to know if this is specific to Ubuntu kernel or mainline.

Toward this end, would you be able to test with vanilla upstream kernel builds from http://kernel.ubuntu.com/~kernel-ppa/mainline/ ?

Yes! It is fairly easy to install a new kernel w/o the Jaunty goodness.

Just download it from the kernel-ppa and use 'sudo dpkg -i' to install it.

e.g. Download a linux-image*.deb file from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.28.9/ (32 or 64-bit) and install it

Or try a newer version of the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.1/

This bug has existed a long time - I noticed it about five years ago.

I have an ASUS Digimatrix HTPC (for MythTV) which has 4xUSB in the front panel and 4xUSB in the back. They are two different controller. I am running Fedora 11 now, but this started way back in Fedora 5.

When I plug my Interlink Versapoint wireless keyboard interface into the rear controller I get the following errors:

The annoying thing is that for my HTPC the cable has to come out of the front and dangle in front of everything for this to work but hey, no big deal. However, because I have a situation in which changing ports fixed the problem perhaps this can help with debugging it.

Because the Digimatrix is such a nice box I picked up a refurb on Ebay cheap and replicated my setup for another location. I have the same issues - so I know it's not a random piece of hardware as I can duplicate it two places.

I have an extra partition and am willing to try to install Ubuntu 9.10 to see if this makes a difference if you think that will help troubleshoot.

Thanks,
Jason

Hello,

I'm experiencing this problem too since the newest kernel upgrade from 2.6.31-14 to 2.6.31-15 on Karmic Koala. I'm attaching my lspci -vvv.
I've experienced the problem with older kernel versions but it seemed to be gone up until now.

Thanks,
Alex

[Alex (e0828440)]

I've attached my dmesg output.
uname -a prints the following:
Linux maxi 2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:54:29 UTC 2009 i686 GNU/Linux

Thanks,

Also experienced this bug using a friend's IPhone with Lucid Beta. In Windows XP it works fine on the same machine.

Got this one too on latest karmic kernel with Samsung MTP device:

https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/483050/comments/17

[Min Pae (sputnik13)]

I am getting this same error. I have been running Karmic without problems through all versions of the kernel released for Karmic.

Upon upgrading to Lucid today, I started to see this message, and my mouse does not work at all.

I upgraded to the 2.6.32-22 kernel from the 2.6.32-21 kernel that was installed during the upgrade, to no avail.

Booting with the 2.6.31-21 kernel that was installed prior to upgrading to Lucid gets rid of the error and my mouse is working fine.

I've attached uname -a, dmesg, and lspci -vvnn for both 2.6.31-21 and 2.6.32-22.

I have a feeling it may be something related to the kernel config or something to do with other configuration files, but I'm no expert with linux USB support.

[Flávio Etrusco (etrusco)]

Min Pae, the posts I found across the web is that this is usually caused by bad electric contact of the usb plug. I suggest you verify there's no residues inside the plug and maybe clean it with cotton swabs...
As it seems, the real bug is that when this problem happens the system freezes for several seconds from time to time.

[Min Pae (sputnik13)]

Falvio, while I appreciate the response, I find it hard to believe that it's a hardware issue given that the system works predictably without a single complaint when I use the older kernel (2.6.31-21) but with the newer kernel (2.6.32-22) it likewise predictably fails. I've tried this several times with both kernels, switching back and forth.

The keyboard and mouse are powered right up to the boot loader. I have a Logitech G500 mouse with LED indicators on the top that are turned on when the mouse is receiving power, but once I get past the boot loader with the new kernel the mouse turns off and does not come back on. With the older kernel everything works fine.

The failure is not sporadic in any way, I've had the system on since last night with the older kernel and it works perfectly.

[Min Pae (sputnik13)]

I attached the wrong file for the 2.6.31-21 kernel lspci.. here's the correct one

[Min Pae (sputnik13)]

[Min Pae (sputnik13)]

Err, sorry for the multiple post, the server said it failed and that I should try gain, which I did, then saw that it posted twice -_-;;

[Flávio Etrusco (etrusco)]

You may be correct, but it doesn't totally invalidate the theory; the kernel may just have been made more picky/correct about errors returned by the USB controller. For me, cleaning the usb plug fixed it.

[Min Pae (sputnik13)]

Everything works great with the latest kernel (2.6.32-22 #36). I've been running on the 2.6.31-21 kernel until this latest update. I don't know what's different, but previously uname -a returned a kernel version of 2.6.32-22 #33, and now it's 2.6.32-22 #36. Obviously something changed between then and now, though I don't nkow precisely what. Unfortunately, I didn't save a copy of the kernel config for the #33 kernel so I can't even do a diff to see whether any options changed..

[Gabriele Tozzi (gabriele-tozzi)]

I had same issue and solved buying a new usb cable.
Maybe this is a cable error problem?

[Min Pae (sputnik13)]

Well, I spoke prematurely. The problem returned after a couple reboots. I don't see how this could be a cable problem when the same device works perfectly fine on my Desktop and both my work Laptop and my personal Laptop. Also, it's not just the mouse, it seems like my printer isn't recognized either. I still think this is a software problem as the older kernels from 9.10 all worked perfectly. I am going to try doing a fresh install of 10.10 at pretty soon to see whether that resolves the problem.

[Dang Nguyen Anh Khoa (wakandan)]

In my case the error happened for no reason. After a lot of rebooting, disabling and re-enabling USB and stuff, I try cleaning the ports with a cotton bud and it works! It could not be, but it was :|
