** Description changed: This problem has been present at least since Maverick (maybe earlier), I'm reporting it only now because it started to annoy me. The hardware: Sony Vaio VPCEB1M1E (for details see attached dmidecode.log and other files). The symptoms: 1) The built in webcam on the laptop isn't detected, /dev/video0 isn't present 2) The kernel constantly logs a stream of the following errors: Nov 13 20:59:46 HOSTNAME kernel: [ 58.092603] usb 1-1.2: new high speed USB device number 83 using ehci_hcd Nov 13 20:59:46 HOSTNAME kernel: [ 58.108761] hub 1-1:1.0: unable to enumerate USB device on port 2 Nov 13 20:59:47 HOSTNAME kernel: [ 58.352608] usb 1-1.2: new high speed USB device number 84 using ehci_hcd Nov 13 20:59:47 HOSTNAME kernel: [ 58.369093] hub 1-1:1.0: unable to enumerate USB device on port 2 Nov 13 20:59:47 HOSTNAME kernel: [ 58.608501] usb 1-1.2: new high speed USB device number 85 using ehci_hcd Nov 13 20:59:47 HOSTNAME kernel: [ 58.625139] hub 1-1:1.0: unable to enumerate USB device on port 2 - I suspect that the webcam not working is related to the kernel errors, as another Vaio user has the same set of problems on Arch Linux: - https://bbs.archlinux.org/viewtopic.php?id=128322 - Note that, regardless of having a nearly identical error signature in the kernel logs, this is probably a different problem than that one: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635573 - The fix for that bug (incorporated into kernel version 3.0.1) probably won't help here as it's specific to nVidia hardware, which isn't present in my situation. - --- + + --- AcpiTables: - Error: command ['gksu', '-D', 'Apport', '--', '/usr/share/apport/dump_acpi_tables.py'] failed with exit code 1: Gtk-Message: Failed to load module "canberra-gtk-module" - Gtk-Message: Failed to load module "canberra-gtk-module" - - (gksu:21084): Gdk-CRITICAL **: IA__gdk_draw_pixbuf: assertion `GDK_IS_DRAWABLE (drawable)' failed + Error: command ['gksu', '-D', 'Apport', '--', '/usr/share/apport/dump_acpi_tables.py'] failed with exit code 1: Gtk-Message: Failed to load module "canberra-gtk-module" + Gtk-Message: Failed to load module "canberra-gtk-module" + + (gksu:21084): Gdk-CRITICAL **: IA__gdk_draw_pixbuf: assertion `GDK_IS_DRAWABLE (drawable)' failed AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
