Dear maintainers,
I'm resending this because the previous email was not clear and should
be ignored. Sorry for the inconvenience caused.
I was using HIK DS-U14 2K camera on Ubuntu 20.04 with built-in MIC
(but it has only one USB cable) but it seems unsupported. It
does not need a driver to be used on Windows (usable by just plugging
in).
I see no HIK devices on the support list
(http://www.ideasonboard.org/uvc/), but when I run lsusb -d 2bdf:0281
-v | grep "14 Video" it does output several lines like these:
bFunctionClass 14 Video
bInterfaceClass 14 Video
bInterfaceClass 14 Video
bInterfaceClass 14 Video
bInterfaceClass 14 Video
It also says "Couldn't open device, some information will be missing".
But it does not require a driver to work on Windows, so it should be a
normal UVC device right?
I observed that it is not supported as a camera, because although I
see /dev/video0 and /dev/video1 (quite odd since it is only 1 camera),
it fails by either OpenCV (cv2.VideoCapture(id)) or `cheese`, where it
says "cannot open by index" (I tried both video0 and video1).
Then I got the logs with `cheese`, in the zip file attached. I think since the
device is quite new on the market, maybe you guys haven't tested it.
BTW, I installed the latest from
https://git.linuxtv.org/media_build.git before I generated the logs.
The camera shows same behavior before and after I installed the latest
version. And the USB connection works fine (I can use other cameras on
this machine), also the camera itself is fine (tested on Windows machines).
Feel free to tell me this is unrelated to the project/this mailing
list, in that case I'll just
get another camera.

Yours sincerely,
Zhengyang

It sounds to me that there's something broken on this camera's
descriptors, with the USB cable or with the USB stack.
It sounds very weird to my eyes to see errors when getting
the device descriptors like those:
Bus 001 Device 007: ID 2bdf:0281 SN0002 HIK 2K USB CAMERA
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 239 Miscellaneous Device

idVendor 0x2bdf
idProduct 0x0281
bcdDevice 11.00
iManufacturer 1 (error)
iProduct 2 (error)
iSerial 3 (error)
The Kernel probe also has similar troubles:

Are you using any proprietary driver or had applied any patch/driver
to the Kernel?
Can you try testing it with vanilla Kernel 5.10?
Thanks,
Mauro

[...]
The "cannot get freq" message comes from the snd_usb_audio driver, and
after that, the video device starts failing ("Failed to set UVC probe
control...").
I suspect that the device firmware has crashed, possibly as a
consequence of requests related to the audio interface.
Zhengyang, could you try to blacklist the snd_usb_audio driver to avoid
it being automatically loaded, and see if the camera then works (after
unplugging and replugging it) ? If it doesn't, please provide the
contents of the kernel log.

Thanks for your through inspections about the log, me too suspect the
problem is related to the audio input, since the audio and video
stream share the same usb cable.
I blacklisted the snd_usb_audio driver, and the camera works fine now.
(I dont really need the audio in the first place so I guess this
solves it)
Thanks very much!
p.s. As for the kernel version, it was 5.8.0-44-generic and I just
installed the ubuntu system a weak ago without adding any customized
patch/driver except for the nvidia GPU.

Both audio and video are supposed to work, so if you want to use audio
as well, I'd recommend contacting the alsa-devel@alsa-project.org
mailing list for support.
