[Bug 1313279] Re: xHCI host not responding to stop endpoint command

FWIW I used method described here
https://bbs.archlinux.org/viewtopic.php?id=236536 and it works for me:

echo -n "0000:00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/unbind
sleep 5
echo -n "0000:00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/bind

Title:
xHCI host not responding to stop endpoint command

Status in Linux:
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).
