Thank you for reporting this bug to Ubuntu.
Ubuntu 14.04 (trusty) reached end-of-life on April 25, 2019.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We appreciate that this bug may be old and you might not be interested
in discussing it any more.
FWIW I used method described here
https://bbs.archlinux.org/viewtopic.php?id=236536 and it works for me:
echo -n ":00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/unbind
sleep 5
echo -n ":00:14.0" | tee /sys/bus/pci/drivers/xhci_hcd/bind

is the most expensive card you can get (I was hoping to rule out certain
things with that).

Title:
xHCI host not responding to stop endpoint
I can now 100% reproduce this:
1) Run an application to test that the connected USB3 device (a 3D camera)
works (cheese).
It works.
2) Power off the 3D camera.
This produces the well-known dmesg lines.
3) Power on the 3D camera; run cheese again: "No device detected".
4) sudo rmmod
I bought a PCI Express USB 3.0 card to overcome the above... invain.
It performed better, in the sense that the xHCI host controller gets
less often unresponsive and that it just works with iommu enabled in
the BIOS as all the other USB did.
However, I STILL get a reproducible freeze up:
[
I'm running ubuntu 18.04 and have the same problems with USB 3.0.
The ONLY way to get it to work at all ever is to turn iommu off in the bios
and use iommu=soft as kernel parameter (as is described as the "solution"
on many forums) AND I need to have certain device plugged into USB and/or
What are the ways to figure out if the symptoms I am seeing is because
of this bug or something else?

I'm way out of date on this, but that patch looks like it was committed
into the Linux kernel in Mach 2015:
https://github.com/torvalds/linux/commit/227a4fd801c8a9fa2c4700ab98ec1aec06e3b44d

I am using kernel 4.4.0-127-lowlatency (Ubuntu 14.04) and I have this
bug. When we run an UVC camera, the host controller dies randomly after
some point. The symptoms are exactly as described by other users above.
I would like to know which kernels this bug affects and where a patch
has been
@jonas - OS version, kernel version? Output of uname -a and lsb_release
-a would help I've not come back to this, having run in USB2 for ~18
months, but it'd be interesting to know if it's still a problem...

Title:
xHCI host not responding to stop endpoint command
I have an Intel NUC D54250WYK running BIOS V32, Ubuntu 14.04 and Unity
with a very similar issue. If I boot with the 290e tuner attached and
then turn on an external DAC, the Cambridge Audio DacMagic 100, all the
USB ports fail. Logs show the same xHCI host crash.
I found two ways to deal with
I will as soon as I can, but it obviously makes the system unserviceable
so it's not something I can do lightly.
Give me a few days and I'll find a quiet time in which I can potentially
destroy my system :-)
