OpenSuse 11.2 - System locks up when using USB mouse

English Hardware
#1

At first I thought this was a scanner problem, but I’ve found that if I’m using the mouse while I’m scanning or sometimes just flipping back and forth with my usb kvm the keyboard and mouse become useless. If I’m scanning while I use the mouse, the system locks up. Here is what I’m seeing in /var/log/messages.
After executing xsane:

Then while the scanner is scanning:

Having received no replies to this thread and as a long time SuSE user, understand that it is a best effort/community-based support, I would like to seek clarification on something. If I purchase the boxed version of 11.2 when it releases in North America, will this type of problem be handled under the support mechanism that is offered with the boxed version? I am referring to the support statement:

For openSUSE users, the supported version of openSUSE may be the best choice—you’ll get complete end-user manual, installable media for x86 and x86 64-bit systems, plus 90 days of end-user installation support via email or phone.

Found on this page:
Buy openSUSE - openSUSE

As a long time SuSE advocate I am willing to pursue paid support avenues for Novell support on this problem. Thanks very much.

Brad

After more forum searches I came across this thread:
System Freeze after 5-10 minutes. It’s the new kernel!! - Page 2 - openSUSE Forums

and I remembered seeing an option to turn off APIC in the BIOS of my new system. While the poster in the thread above disabled apic with an option in the grub menu.lst file, I was able to achieve the same result by disabling APIC in my system’s BIOS.

So the list of all of the mods I did are as follows:

  1. Modify /lib/udev/rules.d/50-udev-default.rules to comment out the line with MODE=“0664” and make it MODE=“0666” for the libusb section. This suppresses the messages that looked like this when I ran xsane:
    libusb couldn’t open USB device /dev/bus/usb/001/001: Permission denied.
    libusb requires write access to USB device nodes.

So make the mod below to fix that.

libusb device nodes

#SUBSYSTEM==“usb”, ENV{DEVTYPE}==“usb_device”, NAME=“bus/usb/$env{BUSNUM}/$env{DEVNUM}”, MODE=“0664”
SUBSYSTEM==“usb”, ENV{DEVTYPE}==“usb_device”, NAME=“bus/usb/$env{BUSNUM}/$env{DEVNUM}”, MODE=“0666”

  1. Made my user a member of the lp group. Even with the fix in step 1, the permissions on the scanner port always were still set to 664. The ownership of the /dev/bus/usb/002/002 object was root.lp so adding myself to the lp group resolved the last of the “libusb couldn’t open usb device” messages.

  2. Disabling APIC in the BIOS resolved the system freeze problem.

Just wanted to share this in case anyone else had a similar problem. I’ve tested this with two long scan jobs (before with APIC enabled it wouldn’t get through one pass of a high res scan) and no problems. To quote the late Freddie Prinze, Sr “Lookin’ good”.

It looks to me like you don’t have suffiecent permissions for your scanner. Check the permissions of your dev and post back here, it should be something like /dev/usb/scanner0.

I agree, you will probably get faster support if you were to purchase the box set, other wise you just have to wait for someone to see your post. There are many of us that are more than willing to help out anytime we can.

Thanks for the reply. As you can see from my prior post, that was part of my problem. There were other issues but I think I’ve got them worked out. But I do thank you for the assistance.

OpenSuse 11.2 64bit
The above information was helpful to me. Thanks for your research. I had to spend a lot of time googling and testing before I got my printer back.

I had been getting error messages similar to the above but my HP C6380 continued to work. Then the scanner started playing up, refusing to scan a full page. It stopped part way through a scan and then it would time out. While trying to remedy this I lost printing as well. I tried to update to a more recent hplip, but found no change in behaviour. I downgraded to hplip 3.9.3-3.4.1 During this time Kwrite was freezing any time I tried to print. I think it still does. But all of my test pages are printing and OpenOffice is printing ok. A test print from Firefox worked as well. I no longer get hpmud permission denied logs.

In the file /etc/udev/55-hpmud.rules we find this.

Novell/Suse changed:

OWNER=“lp” to OWNER=“root”

because OWNER=“lp” is insecure because print job are processed by the user lp

so that a malicious print job might be able to change owner and permissions

of the device nodes and also a user who is allowed to set up a print queue

can set up a special queue with his selfmade driver which changes the

owner and permissions for all device nodes where in contrast OWNER=“root”

is more secure because then only root itself can change owner and permissions.

This change is not distro specific and therefore there is a upstream bug report

https://bugs.launchpad.net/hplip/+bug/410196

MODE=“0660” to MODE=“0664”

because it is sufficiently secure to let any user read the device nodes

because HPLIP opens the device nodes exclusively so that sniffing

of print jobs or scanner image data should not be possible and

read permissions for any user is required in particular for USB devices

so that any user can see the USB devices when he runs the command “lsusb”.

SYSFS{idVendor} to ATTR{idVendor} and

SYSFS{idProduct to ATTR{idProduct}

because SYSFS is deprecated and ATTR works for openSUSE.

Added ENV{sane_hpaio}=“yes” to all entries for USB devices

to get the SANE driver “hpaio” automatically activated in any case

(only scanners in HP parallel port all-in-one devices are ignored)

because not only “AiO products (0x03f0xx11)” can have scanner units

but also Photosmart products, inkjet printers, and laser printers

(e.g. the LaserJet 1220 03f0:0417 has a scanner unit).

An activated SANE driver does not cause continuous system load because

it is only run when the user launches a scanning frontend (e.g. xsane)

and then all what the driver does is to scan the USB device information

to find devices which belong to the driver and if nothing found it exits.

Additionally see https://bugzilla.novell.com/show_bug.cgi?id=469721#c9

Is this causing a big problem for users ?

#7

I’m glad my research helped but I have to tell you that a couple of months ago I switched to Mandriva after being a SuSE user for 7-8 years. I really hate to say this but I found Mandriva to be much more robust and easier from a hardware support perspective. It was all the things SuSE used to be. This is based on my hardware configuration and will vary based on others. But with Mandriva I didn’t have to edit config files by hand and there were consistent, easy to implement steps for ATI graphics driver support. I hope you enjoy OpenSuSE. I enjoyed it until I had all of these issues.
