$ usb-devices I've attached the output of the command.

Observed symptoms: - sometimes the Osprey 2 Mini goes into an endless reset loop (visible as the LEDs on the front of the device flashing rapidly), being reset approximately every 200ms; on such occasions, the Ubuntu user interface often reacts as though I'd inserted an audio CD containing corrupted data (e.g. via repeatedly adding an "Audio CD" icon to the launcher and then removing it, and putting up dialog boxes complaining about failure to read the data). - sometimes the kernel panics (often some time after the reset loop starts, perhaps up to 10 seconds); when this happens there was always or nearly always a reset loop occurring beforehand. - sometimes the device resets once or not at all, then works as expected (showing up as a network interface, and allowing me to communicate to the Internet with a wired connection); I'm currently using an Osprey 2 Mini for this purpose right now. The kernel panics lock up the entire system (forcing a hard power off). lt-Sysrq commands don't work in this state (even though I have them enabled), and sometimes the Caps Lock light flashes repeatedly. The logs end some time before the panic occurs. /var/log/syslog: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1556471/+attachment/4598145/+files/syslog The reset loops also occurred when I was using Ubuntu vivid. The kernel panics only happened after an upgrade to wily. Output of lsusb -v is attached. --- ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ais523 6233 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.10 HibernationDevice: RESUME=UUID=bfbc4bf8-2e40-4799-bbef-9c5044c87007 InstallationDate: Installed on 2014-06-03 (648 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Hewlett-Packard HP Pavilion 15 Notebook PC Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-32-generic.efi.signed root=UUID=e92d655d-cf36-4d45-90e7-30a0f9d0949e ro quiet splash ProcVersionSignature: Ubuntu 4.2.0-32.37-generic 4.2.8-ckt4 RelatedPackageVersions: linux-restricted-modules-4.2.0-32-generic N/A linux-backports-modules-4.2.0-32-generic N/A linux-firmware 1.149.3 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: wily Uname: Linux 4.2.0-32-generic x86_64 UpgradeStatus: Upgraded to wily on 2016-02-18 (22 days ago) UserGroups: adm audio cdrom dip lpadmin plugdev sambashare sudo wireshark _MarkForUpload: True dmi.bios.date: 12/04/2013 dmi.bios.vendor: Insyde dmi.bios.version: F.42 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 2186 dmi.board.vendor: Hewlett-Packard dmi.board.version: 35.12 dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.42:bd12/04/2013:svnHewlett-Packard:pnHPPavilion15NotebookPC:pvr098B110000404100000620180:rvnHewlett-Packard:rn2186:rvr35.12:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP Pavilion 15 Notebook PC dmi.product.version: 098B110000404100000620180 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1556471/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
