https://bugzilla.novell.com/show_bug.cgi?id=223868 Summary: kcontrol logitech mouse settings want to access /proc/bus/usb Product: openSUSE 10.2 Version: RC 1 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE AssignedTo: kde-maintainers@suse.de ReportedBy: robin.knapp@fujitsu-siemens.com QAContact: qa@suse.de Trying to set the advanced settings of logitech mice in KDE Control Center, the applet complains about wrong rights. In documentation "help:/kcontrol/mouse/index.html" there is some information that the applet needs access to /proc/bus/usb which does not exist in udev. Instead /dev/bus/usb should be used. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I'm not entirely sure if resmgr assigns read rights to the right devices.. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=223868 ------- Comment #3 from lnussel@novell.com 2006-11-27 07:24 MST ------- there is no general rule that permits access to usb devices for mice. If you install the lomoco package you get access to all logitech mice supported by lomoco. I condider that a hack as well though. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=223868 ------- Comment #4 from anschneider@novell.com 2006-11-27 07:56 MST ------- You can only poll informations form a USB device so you have to send something to send a request to the device. libusb requires write access to the device to get the device informations. So the user needs write access to /dev/bus/usb. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=223868 ------- Comment #5 from robin.knapp@fujitsu-siemens.com 2006-11-27 13:10 MST ------- I currently cannot get a screenshot and the other info (maybe later today, I'll add it then), but what I can say now: The dialogue was entirely greyed out and there was a message complaining about wrong permissions or that there might be wrong permissions or access problems and you should read the manual. The help page gave some instructions and scripts for "hotplug" (as you can verify yourself) So comment #4 might be right. IIRC this does not work on other current distributions like ubuntu, too, at least I've seen it somewhere else in the past few months. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

also, did you try the module as root or as regular user? I'm not entirely sure if resmgr assigns read rights to the right devices..
oh, forgot to mention, I tries as regular user. I'll try again with user root later... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Perhaps this should be 0666? Note that in 10.2 I already had lots of problems with access to the cdrecorder at /dev/hdc, and solved it by making k3b 4755. I didn't have to do that with 10.1 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
