Public bug reported: since the upgrade to kubuntu 12.10 my usb ports are not working properly anymore. i can use a device that is plugged in while booting or is plugged in shortly after booting.
if i plug the device in a bit (seconds?) later the device is not detected and nothing shows in /var/log/syslog. similarly as soon as i unplug/replug or suspend/resume the device is not detected. the attached dmesg shows the follwing experiment 1) boot (until [99.4] ) 2) wait a couple of seconds 3) plug in external mouse, nothing happens 4) perform the follwing commands from second [923] onwards (i think that 1a.7 and 1d.7 are my two usb ports) echo "0000:00:1a.7" > /sys/bus/pci/drivers/ehci_hcd/unbind sleep 5 echo "0000:00:1d.7" > /sys/bus/pci/drivers/ehci_hcd/unbind sleep 5 echo 1 > /sys/devices/pci0000\:00/0000\:00\:1d.7/remove sleep 5 echo 1 > /sys/devices/pci0000\:00/0000\:00\:1a.7/remove sleep 5 echo 1 > /sys/devices/pci0000\:00/pci_bus/0000\:00/rescan 5) plug in mouse in front usb port, works, unplug 6) plug in mouse in back usb port, works 7) suspend/wakup 8) mouse doesnt react 9) unplug/replug mouse, works ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-17-generic 3.5.0-17.28 ProcVersionSignature: Ubuntu 3.5.0-17.28-generic 3.5.5 Uname: Linux 3.5.0-17-generic x86_64 ApportVersion: 2.6.1-0ubuntu6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: peter 2902 F.... pulseaudio CRDA: country DE: (2400 - 2483 @ 40), (N/A, 20) (5150 - 5250 @ 40), (N/A, 20), NO-OUTDOOR (5250 - 5350 @ 40), (N/A, 20), NO-OUTDOOR, DFS (5470 - 5725 @ 40), (N/A, 26), DFS Date: Sun Nov 11 16:11:37 2012 InstallationDate: Installed on 2012-02-08 (276 days ago) InstallationMedia: Kubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MachineType: Apple Inc.
