This probably denotes a bug in the pwc driver. However, the problem that makes 
your webcam unusable comes from either the XCHI driver, or the interaction of 
the PWC driver with XHCI. Nonetheless, the bug causing this warning should be 
fixed.

Hans, have you tested PWC with XHCI ?

Thanks for the bug report. I've been looking into this, and there
seem to be 2 problems:

1: xhci_hcd 0000:02:00.0: ERROR: unexpected command completion code 0x11.

This seems to be what is causing things to not work with a usb-3 port
for you. Might be fixed by this commit:
https://git.kernel.org/cgit/linux/kernel/git/gregkh/usb.git/commit/drivers/usb/host?h=usb-next&id=3213b151387df0b95f4eada104f68eb1c1409cb3

Can you please do "lspci -nn", and then copy and paste the output here,
so that we can see what sort of xhci controller you've (and try to reproduce
the problem).

2: The triggering of a WARN_ON in __vb2_queue_cancel() when called on
streamoff. I've been looking at the code and I cannot figure out why this
is triggering I'm afraid.

Regards,

Hans

Hmm, so you've both an amd xhci and an etron xhci chip. Do you know to
which xhci the port you're trying to use belongs ? And can you try
with a different usb-3 port ?

I've access to an Etron EJ168 controller, since I specifically bought
one to try and deal with the fact that there quality is, erm, somewhat
lacking. So if this is with the Etron controller I can try to reproduce.

Note I'm about to drop of the internet as I'm going on vacation, I'll be
back Mon 25 Aug.

Regards,

Hans

You can ignore this one.

The uvc driver is doing messy things with vb2 which causes this warning. That
said, it will not break things for you. It is just a warning that the driver
needs to be improved.

I can certainly take the blame when my code needs to be improved, but in this 
case the webcam is supported by the pwc driver, not the uvc driver :-)

It was a bit confusing, but he has two problems: one pwc, one (the warning) for
uvc.

Indeed.
Do I need to provide additional info to help find the root cause(s)?

Kind regards,

Could you help me take a look at the xhci side.

The error:
[53009.847233] xhci_hcd 0000:02:00.0: ERROR: unexpected command completion code 0x11.

Means we got a parameter error, one of the values the xhci driver sends to the controller
in the configure endpoint command is invalid.

This error is causing the "Not enough bandwidth" entries in the log as well, not
really a bandwidth error.

Can you add dynamic debugging, mount debugfs, and do:
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control

Then plug in your usb, and send me the output. 
It should print out the whole input context (all parameters) used in the configure endpoint command

Are my recent additions to
https://bugzilla.kernel.org/show_bug.cgi?id=70531 for kernel 3.16.2 related?

Kind regards,

Right, I've missed the second one, my bad. A similar issue was present with 
the pwc driver, which you have fixed in "[PATCH] pwc: fix WARN_ON" I believe.

I'll have a look at the uvcvideo issue. It can be ignored for now.

Hi,

I have seen similar dmesg message in some other situations (still with 
3.15.6 at least):

Jul 31 00:08:38 daphile user.err kernel: xhci_hcd 0000:02:00.0: ERROR: 
unexpected command completion code 0x11.

Jul 31 00:08:38 daphile user.info kernel: usb 6-2: Not enough bandwidth 
for altsetting 1

Jul 31 00:08:38 daphile user.err kernel: usb 6-2: 1:1: usb_set_interface 
failed (-22)


The problem has been related to the use of USB DAC with NEC uPD72020x 
based PCIe USB card. And the problem is very strange because the some 
DACs work perfectly fine with it and some do not. On the other hand 
those non-working DACs work fine when connected to some other 
(motherboard) USB connector. So it's quite complicated interaction 
problem, who's to blame.

Do you think this could be anyhow related this thread?

That commit already appears to be in my kernel tree.

Hello,

The Logitech C615 works OK if moved away from a USB3 port into a
non-USB3 port.
So it appears a USB3 issue.
Is 'xhci_hcd 0000:02:00.0: ERROR: unexpected command
completion code 0x11' a possible root cause?

My board has:
