["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

** Description changed:

  Steps to reproduce (happens > 50% of the time, but not every time):
  
  Turn on an Osprey 2 Mini, and connect it to a USB port via a USB cable
  while both the device and computer are on (i.e. hotplug).
  
  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.

+ The issue was root caused to the device violating the Mass Storage
+ protocol. Hence, the preferred way to resolve is the vendor provides
+ updated firmware.

Title:
  Connecting an Osprey 2 Mini (USB cellular wireless router) sometimes
  causes an endless reset loop or a kernel panic

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Steps to reproduce (happens > 50% of the time, but not every time):

  Turn on an Osprey 2 Mini, and connect it to a USB port via a USB cable
  while both the device and computer are on (i.e. hotplug).

  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:

  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.

  The issue was root caused to the device violating the Mass Storage
  protocol. Hence, the preferred way to resolve is the vendor provides
  updated firmware.
