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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458631/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
