Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  xHCI host not responding to stop endpoint command

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Description:	Ubuntu 14.04 LTS
  Release:	14.04
  Hardware: Intel NUC D34010WYK (Core i3 4010U)
  Memory: 4 gigabytes
  USD device: PCTV 292e DVB-T tuner

  I have 2 PCTV 292e DVB-T tuners connected to the system. When I start
  to use either of the tuner, the xHCI host crashes. Since I'm booting
  from an USB disk. If I only connect 1 of the tuners, the system works
  ok. It does not matter which one of the tuners I connect.

  [   68.990396] xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command.
  [   68.990402] xhci_hcd 0000:00:14.0: Assuming host is dying, halting host.

  Sometimes this also leads to this:

  [  638.183002] IP: [<ffffffff815325dd>] usb_enable_link_state+0x2d/0x2f0
  [  638.183057] PGD 0 
  [  638.183077] Oops: 0000 [#1] SMP 

  I can also observe the same fault with OpenELEC Linux distribution
  that runs kernel 3.14 when I run the system from an internal SATA SSD
  drive (not from an external USB disk).
