uvideo0: could not open VS pipe: INVAL

C.
Category:
        Webcam / Video

Environment:
        System      : OpenBSD 6.2
        Details     : OpenBSD 6.2 (GENERIC.MP) #5: Fri Feb  2 23:02:19 CET 2018
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
        Architecture: OpenBSD.amd64
        Machine     : amd64

Description:
        The integraged webcam (Lenovo Thinkpad T470, AzureWave Integrated Webcam) does not work.
        It's neither working in Firefox, nor in Chromium, nor in VLC, nor via fswebcam or luvcview.
        The firmware for the uvideo driver has been installed.

How-To-Repeat:
        hiberno:~$ doas luvcview
        luvcview version 2.0
        Video driver: x11
        A window manager is available
        video /dev/video0
        Unable to start capture: 22.
        Error grabbing
  Clean Up done Quit
       
        hiberno:~$ doas fswebcam
        --- Opening /dev/video0...
        Trying source module v4l2...
        /dev/video0 opened.
        No input was specified, using the first.
        Adjusting resolution from 384x288 to 424x240.
        Error starting stream.
        VIDIOC_STREAMON: Invalid argument
        Unable to use mmap. Using read instead.
        --- Capturing frame...
        Timed out waiting for frame!
        No frames captured.

        In both cases the little LED signalling webcam activity is active.


Fix:
        Unknown.

There's currently no support for isochronous transfers on xhci(4).  Some
code is there but it has to be debugged and enabled.

Update to -current and check out sources.
Enable the isoch code in xhci.c (its entry point is under #if 0),
test your webcam (you will find that it won't work), and then
try to tweak xhci.c and uvideo.c until your webcam works.

If those instructions don't help you, either spend more time on it
learning and hacking until you've reached the goal, or wait until
someone else fixes it.

I am afraid hacking on this code myself is way out of my league yet. But
I will try and test this code as soon as time allows to switch to
-current.

Thanks for the hints!
