Such good analysis help us so much! In yast2-scanner I like to add some artificial sleep time between subsequent calls of autodetect_scanners hoping that this helps to avoid the issue. Please add a "sleep 3" line in /usr/lib/YaST2/bin/autodetect_scanners before each of the "sane-find-scanner -q" and "hp-probe -busb -escan" calls as follows: ----------------------------------------------------------------- if [ -x /usr/bin/sane-find-scanner ] then sleep 3 sane-find-scanner -q >$TMP_DATA_RAW & .. if [ -x /usr/bin/hp-probe ] then sleep 3 hp-probe -busb -escan | tr -s '[:blank:]' | grep ... ----------------------------------------------------------------- Then again run "/usr/lib/YaST2/bin/autodetect_scanners YCP" a couple of times at the command line directly one after another. Please report which sleep value works well for you (perhaps "sleep 1" is already sufficient, or you may need even "sleep 10"). The root cause is a low-level timing problem probably somehow related to lower-level USB (i.e. kernel) or perhaps udev or something like this. YaST does not run the programs simultaneously but one after the other and even if such programs would run simultaneously no USB device should get disabled. On a multi-tasking/mulit-user system, it should work when all users run "sane-find-scanner -q" and/or "hp-probe -busb -escan" many times simultaneously. Please try out if running "sane-find-scanner -q" many times or running "hp-probe -busb -escan" many times makes your USB mose disabled. Then I suggest that you make a new separate bug report (probably regarding "kernel") where you describe only the root issue - e.g. something like "running <USB-scanning-program> leads to disabled USB 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.
