Haveyou connected the C270 directly to your computer via USB being sure there are no hubs involved? Then check that camera in the Camera App and device manager to see if its recognised as C270. You might also consider seeing if Logitech provide a driver file for it.
I just updated Zoom Meetings to the latest version and all of the sudden my Logitech C922 Pro Stream webcam stopped working with Zoom meetings. The camera works fine in all other applications that I have tested (Teams, WhatsApp, Logitech settings, Windows Camera). Zoom recognizes that the camera is plugged in, since it is an option under video settings, and the microphone on the camera is working fine in Zoom Meetings. But when I try to enable video in a meeting, it just shows a black screen (or a frozen image if I switch from my built-in camera to the C922). I am fully up-to-date on Windows 10, the latest Zoom version, the camera drivers, and all my graphics drivers. I have tried turning off and on all the settings I can find in Zoom video settings, and restarted my computer multiple times, and nothing has worked.
I have Corel MuliCam Capture software. The frustrating thing is I have a really old PC and it recognizes all 3 webcams without any issues at all, BUT, I have a much, much new PC and no matter what I do, for some reason, it just wont recognize more than ONE webcam!! I have a USB strip and a light comes on next to each device that it recognizes and only ONE light comes on next to ONE of the cameras! What can I do? So, so very frustrating! This is NOT a software issue because it is an issuee of the PC recognizing that the cameras are even there before I even get to the software!
The bad news: It's 100% hardware. On my home computer, I was able to get all webcams to work, but not at the same time. I have a logitec, and 2 off-brand identical cameras. The Logitec plays along side one of the other webcams. But not the identical webcams at the same time. It's firmware or the driver, that can't change. I've tried javascript, java, and many other webcam apps and get the exact same resutls.
The good news: After trying everything on my home computer. (Win10 Dell PC). I finally gave up and tried it on my laptop. (Win10 dell laptop). The first time I tried it, it worked like a charm. All 4 cams worked at the same time. And my new javascript works beautifully, as well as obs. The Logitech, the 2 identical off0brand cams, as well as the built-in cam.
Symptom: The identical cams have the same hardware id (device id), the PC thinks it's one cam and won't play them both at the same time. The Win10 PCwith USB2 ports mostly, and a couple of USB3 ports. The laptop was all USB3 ports.
Solution: You'll need a new PC. Or at least a new USB3 card. I wish I could say exactly what the issue is. But not 100% sure. I'm leaning toward the USB ports. I'm a software expert, so hopefully some hardware expert can expound on exactly what's different between my desktop vs. laptop. No issues at all getting multiple webcams, even if they're identical, to work on my laptop. Also note that my laptop is newer and more powerful than my desktop.

Check for updates. Select Start , then select Settings > Update & Security > Windows Update > Check for updates. If you see the option to View optional updates, select it to see if there are updates available for your camera. Allow available updates to install, then restart your device when it's ready.
After allowing access to the camera, go to Choose which Microsoft Store apps can access your camera and turn on camera access for the apps you want. Only apps installed from the Microsoft Store will show in this list.
I used the default camera App as well as other camera simple software on occasion and both cameras showed up. I mean the app would let me switch between them easily to select which one was currently showing a video display.
Some update or magic event occurred. The camera app ran and blinked yet would show no actual picture. It still showed 2 select-able cameras. It would switch to the other but it too blinked repeatedly having no picture to display.
System Restore was my GOTO for fixing such things. Manually created restore points always drop off over time. Two recent System points showed up but nothing older. Both politely failed to restore at all.
Either works plugged in alone or if they are both plugged in, whoever got there first wins. If the recognized first plugged in camera is removed, the one left is now found. That 'active' designation does not change whether either OR both are plugged in to a USB 2 OR 3 port. I have tested between those choices. The 2nd plugged in one is always the software unseen camera.
It also occurred to me that a change in the Registry could make the 2 cameras appear more separate if their presumably too much alike-ness is the real catch here after the RE-install of Windows 10 Home.
I can't download from this site as it needs me to have a service contract with cisco. All I have is a desk mounted camera that I have aquired so I'm not going to purchase any software for this. Also, I have been to all the cisco and LG released drivers for similar cameras and nothing works (because I have what is a very old camera VID_046D&PID_08B6).
What I think I need is exaclty what Sergey has posted above, the 64bit drivers for Win7 for my very old camera, which I assume the install has been tweaked to get the drivers to work, so anything from cisco is not going to work - I've been through all the threads and various ftp download sites and nothing has worked for me, in particular this thread
We recently deployed Teams Rooms devices across our org. We have about 60 devices currently, all Rallybar w/ Tap and Intel Nuc. I've notice that randomly some devices will get stuck at a blank black screen after nightly reboot. I initially thought this was an issue updating from Teams Rooms v. 4.10.10.0 to 4.11.12.0, however today we had 3 devices get stuck that had already updated to the latest version.
We are having the same issue on our end, too. 20 out of our 50 Rallybars with Taps/Intel Nuc's seem to have this issue every single day so far this week. It's become very frustrating and word is starting to get around that our Teams meeting rooms are starting become....unreliable.
The recommendation from @CheetoChester has worked great on a few Logitech Taps that were already on Windows 10, version 20H2 and only installed the Intel Iris Xe Graphics driver version 30.0.101.1191 after the Windows 10 Feature Update. We can just roll back the drivers as recommended.
However, if the drivers were installed before the Feature Update to 20H2, with the Feature Update installed after the drivers, then the button to "Roll Back Driver" is simply greyed out. We have almost 20 endpoints which fall into this category, as they were all deployed in the past 2 weeks.
Something tells me this will require Intel to publish a newer driver version before we see any real relief. They did release 4 newer sets of drivers since version 30.0.101.1191, which can be found on their support website, though this version is still the latest showing for the Intel NUC that was bundled with the Logitech Tap.
We also introduced another problem (static coming through the rally speaker) during our troubleshooting which according to logitech is caused by latest bios on the NUC. Suggested workaround is to disable Intel Platform Trusted Technology setting in the BIOS, which will kill bitlocker in the process.
@hrcc-cg This is so frustrating, we have only two systems but have the same issue on both with a frozen display every morning. I too got the information from Logitech support to upgrade all drivers (through Windows Update) and we have a "crackling" sound in the MIC now and really low volume on the speakers (We have Rally Medium).
We come across a few users reporting that the NUC MTR systems appear to be frozen or unresponsive after the nightly reboot or after displays go into sleep mode. Tap appears dark and unresponsive. The only recovery is to press and hold the NUC power button until the system shuts down and then power it back on. The root cause is an Intel Iris graphics driver update that was pushed via a Microsoft update.
In light of the latest version(30.0.101.1960) of the Graphics driver released by Microsoft on 10/05/2022 and the fact that you already rolled back to 27.20.100.8935 with no improvement, I would suggest updating the Graphics driver to see if that helps. -graphics-windows-dch-drivers.html
It was also reported that Static noise is heard on Rally Bar, Rally Bar Mini or Rally system connected to the MTR NUC when the system is idle and not on a call.
These issues started after the customer recently updated the NUC BIOS to version 0064. Intel is investigating the issue and has paused the BIOS firmware update version 0064. Microsoft MTR Premium has also stopped pushing this BIOS update via their service. The below workaround worked for most of the users.
