It's not clear from the description what is the problem exactly? I have similar symptoms with "unknown main item tag 0x0" message after timeout.
But my problem is that bluetooth keyboard disconnects on timeout (which is normal), but then, on the first key press it's just loss, while the keyboard reconnects successfully. It doesn't occurs on the same system with Windows 10 - the key doesn't lost on reconnect. I wonder if it can be the same problem. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1385113 Title: hid-generic 0005:099A:0500.0001: unknown main item tag 0x0 Status in Linux: Unknown Status in linux package in Ubuntu: Confirmed Bug description: Message with Mouse Bluetooth [ 32.960478] hid-generic 0005:099A:0500.0001: unknown main item tag 0x0 ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-3.16.0-23-generic 3.16.0-23.31 ProcVersionSignature: Ubuntu 3.16.0-23.31-generic 3.16.4 Uname: Linux 3.16.0-23-generic x86_64 ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: caravena 3344 F.... pulseaudio CurrentDesktop: GNOME Date: Fri Oct 24 05:22:54 2014 HibernationDevice: RESUME=UUID=360bd2d2-4f44-4311-86d6-4781ac81ee87 InstallationDate: Installed on 2014-09-25 (29 days ago) InstallationMedia: Ubuntu-GNOME 14.10 "Utopic Unicorn" - Alpha amd64 (20140923) MachineType: SAMSUNG ELECTRONICS CO., LTD. 530U3C/530U4C ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/@/boot/vmlinuz-3.16.0-23-generic root=UUID=0fb75fae-baa3-428b-ace4-498e69ff7fb6 ro rootflags=subvol=@ quiet splash nomdmonddf nomdmonisw nomdmonddf nomdmonisw vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.16.0-23-generic N/A linux-backports-modules-3.16.0-23-generic N/A linux-firmware 1.138 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/15/2013 dmi.bios.vendor: Phoenix Technologies Ltd. dmi.bios.version: P14AAJ dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: SAMSUNG_NP1234567890 dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: FAB1 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: 0.1 dmi.modalias: dmi:bvnPhoenixTechnologiesLtd.:bvrP14AAJ:bd04/15/2013:svnSAMSUNGELECTRONICSCO.,LTD.:pn530U3C/530U4C:pvr0.1:rvnSAMSUNGELECTRONICSCO.,LTD.:rnSAMSUNG_NP1234567890:rvrFAB1:cvnSAMSUNGELECTRONICSCO.,LTD.:ct9:cvr0.1: dmi.product.name: 530U3C/530U4C dmi.product.version: 0.1 dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD.
