[Regression]Samsung ML-2010 Printer gets constantly re-detected

[Erik Andrén]

Binary package hint: linux-image-2.6.22-8-generic

This is a regression from feisty.
My Samsung ML-2010 gets constantly redetected using the 2.6.22-8 generic kernel. Booting into the 2.6.20-15-generic resolves the issue.
Verified on two computers.

dmesg is filled with these entries:

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.

From where your 2.6.20-15-generic kernel image come from?

I see you have isolated pertinent information, but please, give the following information anyway.
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 "sudo 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/KernelTeamBugPolicies. Thanks in advance!

I have identical problem with this printer when I using 2.6.22 kernel with Feisty and new Gutsy. With early version kernel e.g. 2.6.20 work perfectly, system detect printer and install. Verified on two computers, too.
I read about this problem connected with "usb_suspend" and powersaving usb. If possible to correct this bug in new version kernel? Sorry for my english.

[Erik Andrén (erik-andren)]

piter10,
yes, the autosuspend feature is likely the cause of this bug. See: http://lkml.org/lkml/2007/8/3/273

[Paul Dufresne (paulduf)]

Thanks Piter10.
But please, from now when asked to attach files, under the textarea to enter comment, there is a 'Attachment:' with a browse button near that.
Please use that rather than copy the result of the command.

Well, confirming, this is a bit too technical for me for feeling at ease to request more specific infos.

[sonsnix (markus-sons)]

I can confirm this bug. Setting usbcore.autosuspend=-1 solves the problem. (located in /sys/module/usbcore/parameters)

You can set this parameter permanently, if you install sysfsutils and edit the /etc/sysfs.conf

But I'd also appreciate a more elegant solution to this problem.

[Sitsofe Wheeler (sitsofe)]

(Subscribing sonsnix to this bug so reply is seen)

Please post the output of
lsusb
along details of which kernel you are using and a link to this bug report over in Bug #85488 so your printer can make its way on to the quirks list...

[Erik Andrén (erik-andren)]

The ML-2010 will be autosuspend blacklisted in 2.6.23

[Sitsofe Wheeler (sitsofe)]

What Erik says is correct (see http://git.kernel.org/?p=linux/kernel/git/gregkh/usb-2.6.git;a=history;f=drivers/usb/core/quirks.c;hb=a78d702beed61956b26c1b6288da868946642317 ). I cannot say whether this will be backported to Gutsy (someone will have to check to the appropriate git tree).

[Henrik Nilsen Omma (henrik)]

A cherry pick for this would be nice if the patch is simple.

[Erik Andrén (erik-andren)]

This is now resolved.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
