apport information ** Tags added: apport-collected vivid
** Description changed: With ubuntu vivid i see a /dev/input/js0. I do not have a joystick or gamepad attached. This invalid input device cause a game in steam "Crypt of the necrodancer" to crash during start. The game works fine when I delete it. This appears to be a ubuntu specific bug as it does not show up on fedora 22. It goes away if I unplug the mouse/keyboard usb dongle I use. If I attach a wired keyboard only it does not show up. I tried adding a wired mouse too, but that causes js0 to appear too. The output of udevadm changes depending on what mouse I have attached. The following output is from using the dongle for my wireless mouse/keyboard (both microsoft products) $sudo udevadm info /dev/input/js0 P: /devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.2/0003:045E:0745.0003/input/input7/js0 N: input/js0 S: input/by-id/usb-Microsoft_Microsoft®_2.4GHz_Transceiver_v6.0-if02-joystick S: input/by-path/pci-0000:00:1a.2-usb-0:1:1.2-joystick E: DEVLINKS=/dev/input/by-id/usb-Microsoft_Microsoft®_2.4GHz_Transceiver_v6.0-if02-joystick /dev/input/by-path/pci-0000:00:1a.2-usb-0:1:1.2-joystick E: DEVNAME=/dev/input/js0 E: DEVPATH=/devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.2/0003:045E:0745.0003/input/input7/js0 E: ID_BUS=usb E: ID_FOR_SEAT=input-pci-0000_00_1a_2-usb-0_1_1_2 E: ID_INPUT=1 E: ID_INPUT_JOYSTICK=1 E: ID_INPUT_KEY=1 E: ID_INPUT_KEYBOARD=1 E: ID_MODEL=Microsoft®_2.4GHz_Transceiver_v6.0 E: ID_MODEL_ENC=Microsoft®\x202.4GHz\x20Transceiver\x20v6.0 E: ID_MODEL_ID=0745 E: ID_PATH=pci-0000:00:1a.2-usb-0:1:1.2 E: ID_PATH_TAG=pci-0000_00_1a_2-usb-0_1_1_2 E: ID_REVISION=0251 E: ID_SERIAL=Microsoft_Microsoft®_2.4GHz_Transceiver_v6.0 E: ID_TYPE=hid E: ID_USB_DRIVER=usbhid E: ID_USB_INTERFACES=:030101:030102:030000: E: ID_USB_INTERFACE_NUM=02 E: ID_VENDOR=Microsoft E: ID_VENDOR_ENC=Microsoft E: ID_VENDOR_ID=045e E: MAJOR=13 E: MINOR=0 E: SUBSYSTEM=input E: TAGS=:seat:uaccess: E: USEC_INITIALIZED=117298 + --- + ApportVersion: 2.17.2-0ubuntu1.1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: phomes 1442 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 15.04 + HibernationDevice: RESUME=UUID=fde58bd6-316d-4a14-bc85-41d8f26cec02 + InstallationDate: Installed on 2015-03-13 (91 days ago) + InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Alpha amd64 (20150306) + MachineType: Hewlett-Packard HP Z400 Workstation + NonfreeKernelModules: nvidia + Package: linux (not installed) + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-20-generic root=UUID=0fad5f38-47ef-4b98-b2ac-1ff9fc3244be ro quiet splash + ProcVersionSignature: Ubuntu 3.19.0-20.20-generic 3.19.8 + RelatedPackageVersions: + linux-restricted-modules-3.19.0-20-generic N/A + linux-backports-modules-3.19.0-20-generic N/A + linux-firmware 1.143.1 + RfKill: + 0: phy0: Wireless LAN + Soft blocked: no + Hard blocked: no + Tags: vivid + Uname: Linux 3.19.0-20-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 07/15/2013 + dmi.bios.vendor: Hewlett-Packard + dmi.bios.version: 786G3 v03.57 + dmi.board.asset.tag: CZC94164B9 + dmi.board.name: 0AE4h + dmi.board.vendor: Hewlett-Packard + dmi.board.version: C + dmi.chassis.asset.tag: CZC94164B9 + dmi.chassis.type: 6 + dmi.chassis.vendor: Hewlett-Packard + dmi.modalias: dmi:bvnHewlett-Packard:bvr786G3v03.57:bd07/15/2013:svnHewlett-Packard:pnHPZ400Workstation:pvr:rvnHewlett-Packard:rn0AE4h:rvrC:cvnHewlett-Packard:ct6:cvr: + dmi.product.name: HP Z400 Workstation + dmi.sys.vendor: Hewlett-Packard ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1458631/+attachment/4414261/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1458631 Title: udev: /dev/input/js0 is created but no joystick attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458631/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
