Definitely a suspend/resume issue, I can reproduce the camera failing to work (but not the oops) by doing a suspend/resume.
After resuming, I'm getting the following in kern.log: > Oct 24 20:49:58 localhost kernel: [23531.320070] usb 3-2: new full speed USB > device using uhci_hcd and address 41 > Oct 24 20:49:58 localhost kernel: [23531.860070] usb 3-2: device not > accepting address 41, error -71 > Oct 24 20:49:58 localhost kernel: [23531.920126] hub 3-0:1.0: unable to > enumerate USB device on port 2 > Oct 24 20:50:13 localhost kernel: [23546.750093] hub 1-0:1.0: unable to > enumerate USB device on port 2 After unloading/reloading pwc.ko and videodev.ko, it gets a bit further, but still does not work: > Oct 24 21:11:36 localhost kernel: [24830.015689] Linux video capture > interface: v2.00 > Oct 24 21:11:36 localhost kernel: [24830.022038] pwc: Philips webcam module > version 10.0.13 loaded. > Oct 24 21:11:36 localhost kernel: [24830.022045] pwc: Supports Philips > PCA645/646, PCVC675/680/690, PCVC720[40]/730/740/750 & PCVC830/840. > Oct 24 21:11:36 localhost kernel: [24830.022051] pwc: Also supports the Askey > VC010, various Logitech Quickcams, Samsung MPC-C10 and MPC-C30, > Oct 24 21:11:36 localhost kernel: [24830.022056] pwc: the Creative WebCam 5 & > Pro Ex, SOTEC Afina Eye and Visionite VCS-UC300 and VCS-UM100. > Oct 24 21:11:36 localhost kernel: [24830.022123] usbcore: registered new > interface driver Philips webcam > Oct 24 21:11:43 localhost kernel: [24836.480092] usb 5-2: new full speed USB > device using uhci_hcd and address 4 > Oct 24 21:11:43 localhost kernel: [24836.767349] usb 5-2: configuration #1 > chosen from 1 choice > Oct 24 21:11:43 localhost kernel: [24836.772692] pwc: Logitech QuickCam 4000 > Pro USB webcam detected. > Oct 24 21:11:43 localhost kernel: [24836.772777] pwc: Registered as > /dev/video0. > Oct 24 21:11:43 localhost kernel: [24837.062269] input: PWC snapshot button > as /devices/pci0000:00/0000:00:1d.0/usb5/5-2/input/input11 > Oct 24 21:11:58 localhost kernel: [24851.820083] usb 3-2: new full speed USB > device using uhci_hcd and address 59 > Oct 24 21:11:58 localhost kernel: [24852.002573] usb 3-2: configuration #1 > chosen from 1 choice > Oct 24 21:11:59 localhost kernel: [24852.185401] usb 3-2: usbfs: > USBDEVFS_CONTROL failed cmd rhythmbox rqt 128 rq 6 len 255 ret -71 > Oct 24 21:11:59 localhost kernel: [24852.186423] usb 3-2: usbfs: > USBDEVFS_CONTROL failed cmd rhythmbox rqt 128 rq 6 len 1024 ret -71 > Oct 24 21:11:59 localhost kernel: [24852.290148] usb 3-2: USB disconnect, > address 59 > Oct 24 21:12:46 localhost kernel: [24900.030089] hub 1-0:1.0: unable to > enumerate USB device on port 2 > Oct 24 21:12:59 localhost kernel: [24913.102604] hub 1-0:1.0: unable to > enumerate USB device on port 2 > Oct 24 21:13:02 localhost kernel: [24915.142588] hub 1-0:1.0: unable to > enumerate USB device on port 2 > Oct 24 21:14:03 localhost kernel: [24977.070077] usb 3-2: new full speed USB > device using uhci_hcd and address 60 > Oct 24 21:14:04 localhost kernel: [24977.220409] usb 3-2: device descriptor > read/all, error -71 > Oct 24 21:14:04 localhost kernel: [24977.280104] hub 3-0:1.0: unable to > enumerate USB device on port 2 > Oct 24 21:14:34 localhost kernel: [25007.170108] hub 1-0:1.0: unable to > enumerate USB device on port 2 etc. -- Oops unplugging Logitech QuickCam Pro 4000 https://bugs.launchpad.net/bugs/459517 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
