Suggestions for a recently broken webcam?

[ender_01]

Updated everything this week (Dec 15, 2024) and my once perfectly working webcam has now stopped working. Do some digging I’ve found the recent commit; (which I can’t link to, how unhelpful)

https://lore.kernel.org/linux-media/20240913180601.1400596-2-cascardo@igalia.com/T/#u

Which is in the 6.6.65 kernel, and is now running by default. The line in question is this new statement;

 +	/* Per UVC 1.1+ spec 3.7.2, the ID is unique. */
 +	if (uvc_entity_by_id(dev, id)) {
 +		dev_err(&dev->udev->dev, "Found multiple Units with ID %u\n", id);
 +		return ERR_PTR(-EINVAL);
 +	}

When I plug my webcam in I get the error;

[ 3401.980695] usb 5-1.2: Found multiple Units with ID 5

And no video devices are detected when doing normal video things. The device shows up in lsusb, but the new uvc code is just bricking it.

lsusb -d 1b3f:2247 -v output is below.

I’m not sure what to do with this. The uvc-devel mailing list seems to be dead, and the troubleshooting page says to point errors there. Seems unfortunate that I now may need to go buy a new webcam because of this change.

Any ideas on the proper channel to put this through? newb here when interacting with the linux dev/driver community. Also, just want this documented for other users to potentially find, even if there is no resolution here.

Hi @ender_01, and welcome!

@ender_01

Do some digging I’ve found the recent commit; (which I can’t link to, how unhelpful)

Welcome to the Manjaro Community!

Unfortunately I’m in the same boat. “General Webcam” not recognized under linux612 either, tested with Cheese and Webcamoid. Hopefully someone will know where to report this; not something I’ve done yet.

The HK 2M Webcam works fine; just tested it on this machine (it’s used on the other one for Skype calls and that system hasn’t been given the latest raft of updates yet).

Welcome to the Manjaro community.

With respect the Linux kernel I might suggest directing any queries to the kernel maintainer Linus Torvalds.

I see this was taken more seriously than intended. In my own defense, I have been rather sick of late, and communication clearly suffers.

---

In as far as help that Manjaro forum members might be able to offer, please provide at minimum required system information.

---

As a new forum user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit:

• How to Post
• How to Request Support
• Forum Rules
• Manjaro Wiki

The Update Announcements should be checked frequently for important update related information.

These announcements contain a Known Issues and Solutions section and should generally be checked before posting a request for support.

Output of the following command formatted according to forum requirements (see links above) may be useful for those wishing to help:

inxi --admin --verbosity=8 --filter --no-host --width

Be prepared to provide more information and outputs from other commands when asked.

Regards.

Just to let you know that in my case it appears to be a dodgy USB connection. Probably at the camera end; will investigate. I’ve just had the thing working (briefly) using Cheese.

ETA: It’s working again. Could be the USB socket being a bit tarnished or full of crud, or both.

[ender_01]

@BG405 , I’ve tried multiple ports, had the same though. Gone through ports on the motherboard itself to hubs to whtever, doesn’t matter, same deal. Again, it sees the camera just fine via lsusb, but there is an error, from I believe UVC that stops it from working.

inxi output below. You can see the GENERAL WEBCAM in the output there as well, again, proving the usb bus is seeing the device, it’s just not seen as a video device.

Also, running
v4l2-ctl --list-devices
results in the output of
Cannot open device /dev/video0, exiting.
because it in fact doesn’t exist.

Have you tried linux612? May not fix it but it’s worth a go.

N.B. I do see that you have no swap defined which, although not likely directly related to this issue, is something which I’d strongly recommend attending to, even with 64G of RAM.

[cscs]

@soundofthunder

With respect the Linux kernel I might suggest directing any queries to the kernel maintainer Linus Torvalds .

Please do not go trying to find Linus to complain about some perceived issue with the linux kernel. And please dont suggest others do so.

And Linus is not even the maintainer of kernel 6.6.

Greg Kroah-Hartman and Sasha Levin are.

But do not go hunting down any of those individuals to contact them directly about whatever random problem you might have. Thats not how things are done. Maybe certain circumstances would make it more or less acceptable … but its hardly something we should be advising others to do whenever we think some issue is related to the kernel.

[ender_01]

@cscs hah, no worries, I wasn’t about to go email Linus about this and agree with your sentiment.

I was more looking to see if folks have experience with bug reporting, and the best approach here, mailing list? bug tracker? whatever. I figure there must be some knowledge on these forums about that type of thing.

The group responsible for this part of the code isn’t clear to me. The patch I posted above is under linux-media, but this is obviously UVC related code, but that particular mailiing list hasn’t seen activity in 2 years and points to a sourceforge project. (sidebar; sourceforge seem to be in a sad state these days to anyone else?)

@BG405 , a newer kernel was on my list to test, but didn’t have high hopes due to the code being recently added, like in the last month or two, which likely means it’s in all new kernels moving forward. I’ll still give it a shot when i have some time though.

Also, I’ll review the swap. It’s been so long since I did a fresh install, I don’t remember if I actively configured 0 swap for some reason, or that’s just the default and I didn’t configure it. I also haven’t had any issues, as far as I know, related to the swap space.

[adriaticc]

Hi @ender_01. I’ve got a similar generic webcam which broke for presumably the same reason. I haven’t used swap for at least a decade, so you’re in good company The vendor product pair of the camera in question is 1b3f:1167. Branding on the device says Depstech 2k.

I’ve confirmed the camera does in fact work when removing that error guard, but you’ll likely see a kernel stack trace in dmesg similar to what’s documented in the relevant commit (media: uvcvideo: Require entities to have a non-zero unique ID · torvalds/linux@3dd075f · GitHub), as well as the error “Failed to create links for entity 5”.

I’ll read a little more deeply to see if I can grok what’s happening here. Pure speculation and a glance at the spec leads me to believe that devices report a number of “units and terminals” (called entities for the purposes of this driver) which are logical thingamajigs chained together to describe the functionality of some device. I think a unit would be something like the backlight compensation or white balance controls, and a terminal would be a video source or sink. And UVC standardizes this in such a way that drivers can enumerate and keep track of all these entities, and our devices are reporting units and/or terminals with non-unique ids. Specifically whatever two things are claiming bTerminalID == 5 or bUnitID == 5 in their descriptors.

Presumably we can examine this with some good old fashioned printk debugging and perhaps add a vendor quirk to yeet (see: nerf) this misnumbered entity number 5. If you’d like to try your hand, make sure you’ve got your build-essentials and linux-headers packages, get the linux source with pkgctl repo clone linux && cd linux && makepkg -od (or equivalent tarball if you don’t have those tools handy), comment out those lines you identified and do something like:

make -C /lib/modules/$(uname -r)/build M=/applicable/version/linux/source/drivers/media/usb/uvc modules
sudo cp /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/uvcvideo.ko.zst{,.bak}
sudo zstd /applicable/version/linux/source/drivers/media/usb/uvc/uvcvideo.ko -o /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/uvcvideo.ko.zst
sudo modprobe -r uvcvideo
sudo modprobe uvcvideo

You should find your camera working, albeit with a stack trace here and there. Invoke your favorite deity and backup your data.

@adriaticc
A warm welcome to the Manjaro Forum and a compliment on your first post here!

Cheers!
