Hello,
I encountered regression (breakage) for the Grandstream GUV3100 webcam
(ID 2bab:0011) in the uvcvideo driver.
Testing showed that the camera WORKS on kernel 6.16.8.arch3-1.
However, it does NOT WORK on newer kernel versions, including the
latest stable version (6.17.1.arch1-1) and the latest LTS kernel
version (6.12.51-1).
Problem: The driver finds the device but cannot start the video
stream, resulting in an error in dmesg: “No streaming interface found
for terminal 65535.”
I checked all known quirks (0x128, 0x100, 0x400) without success. The
logs attached below were collected on a non-working kernel with the
quirks=0x400 parameter applied.
I hope this information will help restore device support.
Thank you for your work!

Hi Angel4005,
As you are on Arch, can you try v6.12.48 LTS from the package archive?
It was released on the same day as v6.16.8 so it's hopefully good too.
If you can find the exact v6.12 series release which introduced the
breakage things may get easier, because there are much fewer commits
to worry about between releases in those LTS series.
These are the only drivers/media changes between v6.12.48 and v6.12.51:
000b2a6bed7f media: uvcvideo: Mark invalid entities with id UVC_INVALID_ENTITY_ID
fd5d3e6b149e media: rc: fix races with imon_disconnect()
effb1c19583b media: tuner: xc5000: Fix use-after-free in xc5000_release
514a519baa9e media: b2c2: Fix use-after-free causing by irq_check_work in flexcop_pci_remove
Perhaps the first one? Consider this dmesg line:
[ 363.700829] usb 1-1.3: No streaming interface found for terminal 65535.
There is also a few drivers/usb changes, but I doubt they are relevant.
Regards,
Michal

Hi Angel
Thank you very much for the detailed report.
Your device has two entities with the same id:
VideoControl Interface Descriptor:
bLength 31
bDescriptorType 36
bDescriptorSubtype 6 (EXTENSION_UNIT)
bUnitID 4
ideoControl Interface Descriptor:
bLength 9
bDescriptorType 36
bDescriptorSubtype 3 (OUTPUT_TERMINAL)
bTerminalID 4
wTerminalType 0x0101 USB Streaming
bAssocTerminal 0
bSourceID 3
iTerminal 0
And that confuses the code. We have recently introduced a change that
has probably triggered the regression
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/media/usb/uvc?id=0e2ee70291e64a30fe36960c85294726d34a103e
Do you know the commercial name of the device and if it is available to buy?
Could you try this patch and let me know if it fixes the issue?

Hello,
Thank you very much for your quick and helpful responses!
I confirm that the problem seems to be related to duplicate IDs in the
descriptor of my Grandstream GUV3100 device.
Unfortunately, I was unable to test the proposed patch, as kernel
building is beyond my current capabilities. I am not experienced in
such matters and do not want to risk the stability of my system.
The exact breaking point when the camera stopped working was found:
* Last known WORKING kernel (GOOD): 6.12.50-1-lts
* First known NON-WORKING kernel (BAD): 6.12.51-1-lts
I hope this information will help pinpoint the commit that caused the
regression.
Thank you very much for your help, guidance, and understanding!

We know which commit caused the regrassion, but it's hard to fix the
issue properly without being able to test on the device. That's why
Ricardo asked if the camera can be easily bought from somewhere.

My Grandstream GUV3100 camera is easy to buy. It is not a rare or
exclusive camera. It can be purchased from about 30 local online
stores in my country.

Can you perhaps ask for help on the forum of your distribution?
Chances are someone can help by building and providing 6.12.51
kernel-pkgs for your distribution with the suggested patch added
to the build. Then you can just install these pkg with your
regular distro package manager which should be easy and safe
to do.

Hans
