Bug Description

1) lsb_release -rd
Description: Ubuntu intrepid (development branch)
Release: 8.10

2) apt-cache policy linux
linux:
  Installed: (none)
  Candidate: 2.6.26.5.7
  Version table:
     2.6.26.5.7 0
        500 http://us.archive.ubuntu.com intrepid/restricted Packages

3) I expect for the system to boot up without errors.

4) The system boots up and endlessly repeats:

[...]

[ 599.518833] hub 4-0:1.0: unable to enumerate USB device on port 5
[...]

<b>Updates</b>

This bug is still present in Ubuntu 9.04 and Ubuntu 9.10, for example in 2.6.31-14-generic-pae. It makes consoles almost impossible to use, and causes a lot of writes due to the constant updating of /var/log/syslog.

A suggestion of the cause is at http://lkml.org/lkml/2008/10/24/209

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.

I disagree that the message is harmless.

I see a distinct drop in response to my USB keyboard on the machine running Intrepid v.s. a nearly identical machine running Hardy. There are other processes affected as well, that's just the most obvious. The process generating the message is running in a tight unending loop. This never a good thing for an operating system routine to do without purpose.

[ 25.700052] hub 1-0:1.0: unable to enumerate USB device on port 6

Those two lines since I boot my laptop (Acer Aspire 5520-5281)
I never saw this problem on 8.10.

Cheers.

NEVER ENDING

also on syslog

Ctrl+Alt+F1 tty UNUSABLE and produces the same error message repeatedly by line.

i remembered i tried the last or one of the last kernel versions (2.6.35.????) for ubuntu 10.10 on an 11.04 upgrade, and these messages didnt appear after grub boot (removed 'quiet splash' from grub to see)

however there were some errors on starting some default applications. and a bit of a slow startup.

so now i've updated the bios and did a clean ubuntu reinstall, but to no avail. faster startup but error message still appears. Trying both the amd64 standard and alternate installers. I might try the i386 32 bit one next. but since this is 64 bit capable system with 4gb of mem, the 64 bit one seems the better choice.

aside from error messages things seem to work normally.

this report below might be related: (same error, same nvidia mcp67 controller)
https://lists.linux-foundation.org/pipermail/bugme-new/2010-November/025981.html

also to note that alternate install seems to get some updates from internet during installation. so am not sure if default install of ubuntu without internet would produce the error.

also saw this error on a recent Clonezilla on the same computer, rendering clonezilla unusable. but using an older i386 (or ?686) CD works without the error.

oh also ive tried
1.) the unbind commands mentioned above for ls /sys/bus/pci/drivers/ehci_hcd
the devices disappeared from ls /sys/bus/pci/drivers/ehci_hcd, but the error messages still appear on kern.log.
2.) unplugging the laptop and removing the battery as mentioned in forums, to no avail.
3.) also tried update-usbids at terminal (error still goes on and on)

others can try these though, in case their error message is caused by something else

(also upgraded bios to latest from HP site released this year to no avail)

so next step for me is to install all updates for this amd64 installation, see if fixed.

if not try out the unplugging method again.

then if not try installing the 32 bit ubuntu 11.04 desktop.

Well looks like nobody's assigned to this bug. Still, it is confirmed.

So a workaround worked:

at first simply unbinding ehci entries worked inconsistently, but also unbinding ohci entries did the trick.

adding the following to /etc/rc.local worked for me:
#unbind ehci (USB2.0) and ohci (USB1.1)
echo -n 0000:00:02.1 | tee -a /sys/bus/pci/drivers/ehci_hcd/unbind
echo -n 0000:00:02.0 | tee -a /sys/bus/pci/drivers/ohci_hcd/unbind
echo -n 0000:00:04.1 | tee -a /sys/bus/pci/drivers/ehci_hcd/unbind
echo -n 0000:00:04.0 | tee -a /sys/bus/pci/drivers/ohci_hcd/unbind
# note the 0's and 1's differences in ehci and ohci
# change the numbers according to your entries in ls /sys/bus/pci/drivers/ehci_hcd (and again in ohci_hcd)

# bind them back
echo -n 0000:00:02.1 | tee -a /sys/bus/pci/drivers/ehci_hcd/bind
echo -n 0000:00:04.1 | tee -a /sys/bus/pci/drivers/ehci_hcd/bind

# i left these two out, because sometimes rebinding too soon made the error reoccur:
#echo -n 0000:00:02.0 | tee -a /sys/bus/pci/drivers/ohci_hcd/bind
#echo -n 0000:00:04.0 | tee -a /sys/bus/pci/drivers/ohci_hcd/bind
# i just rebind ohci from terminal for the USB mouse.

# at terminal
#echo -n 0000:00:02.0 | sudo tee -a /sys/bus/pci/drivers/ohci_hcd/bind
# sudo needed for binding and unbinding

linux - ubuntu gurus:
is there a way to unbind sooner and then rebind right before the desktop screen? Kindly provide complete instructions if you can, thanks.

(the error still appears right after SATA scsi Hard drive configuration and after the usb mouse is detected. Then disappears when the unbinding script kicks in.
That's why there is a need to unbind sooner, or maybe put off original initial binding to a later time)
Will probably look into this when i have some more time. put in considerable hours already into this one.

guess kernel can be modified. But dont know how to do that, yet.

Hello

I'm not completely sure this is the exact issue I have, however when I look at syslog (that's what you can see at [ctrl]+[alt]+[F7], right?*) I have new "unable to enumerate USB device on port 6" appearing every half second or so, after having my computer asleep.
It only happens every now and then, however I think that it's related to USB-devices being connected when the sleep is initiated, as it usually seems related to my webcam, which is USB-connected, but cannot be detached since it is kinda built into my laptop.

I have found two ways to stop this. The one can be found at http://www.absolutelytech.com/2010/04/18/solved-unable-to-enumerate-usb-device-disabling-ehci_hcd/, the other is to simple open Cheese (the webcam program), force quit it when it turns grey, and then when my webcam indicator blinks it works. The last one however, I only tried once so far, but will retry again when i have the chance.

Now, is there any further info I can provide to resolve this?

Sorry this is so messy, I'm preparing for exams right now, so this is really slack :)

* I ask because I can't seem to find any documentation on the behaviour of the [ctrl]+[alt]+[F?] buttons anywhere. I havn't bothered till now btw, so maybe I just havn't searched thoroughly enough

@Franco (sed: couldn't flush stdout: No existe el dispositivo)
I got the same message although in German ;-).

Workaround:
Edit /etc/rc.local

Insert the following:

cd /sys/bus/pci/drivers/ehci_hcd
for i in `ls -d 0000:00:*`;do echo $i > unbind;sleep 5; echo $i > bind; done

See also #79 (Thanks to J B).

You see: I unbind and then bind the ehci entries again. If I don't bind the entry again, one of the message keeps spaming the console. Binding again let vanish the messages.

Compared to J B's suggestions I had not to touch the ohci entries.

I've pretty much given up getting usb to work on this laptop. If I unbind the driver from one port then the issue comes back a little later on a different one. I keep meaning to boot it into Windows to confirm that it is in fact a hardware error and will follow up here if I ever do. To avoid spamming the console I just boot with the nousb kernel option.

update on this is that bluetooth actually stopped working on the laptop the unbind fix was applied on.
so it was not a real fix if i wanted to use bluetooth.

bluetooth works on windows.

other info which might be related:
- for this laptop, bluetooth is also disabled in ubuntu if it was switched off in windows. this was already discussed in http://ubuntuforums.org/showpost.php?p=8720388&postcount=5

anyway,
gave up on it and just mainly use windows on that laptop now after the ubuntu partition stopped working even after reformat/reinstall. failed most probably due to overheating issues (separate laptop issue). unable to enumerate error looks disruptive to the installation as well.

the laptop's days are numbered. unless a hardware fix is applied. probably later.

The kern.log has this line:

Jul 24 10:41:38 Lexington kernel: [ 6100.207979] hub 1-7:1.0: unable to enumerate USB device on port 3

repeat without stopping while the computer is powered up. The time changes but the message repeats over and over.

mark@Lexington:~$ uname -r
3.8.0-26-generic

however this is Xubuntu.

I have an issue with the system being able to see a USB drive. I know the port works because I can plug in a wireless mouse receiver to my USB port.
