Logitech G Hub Camera Not Available

Set object-specific properties for the webcam object to use with any webcam. You can also set device-specific properties for a specific webcam, if supported by your device. Use dot notation to set object-specific or device-specific properties.
To set an object-specific property, use the object name and property name in dot notation as the first argument, and the value you want to set as the second argument. Property names and values can be character vectors or numerics. This example sets the camera resolution to the value shown for the webcam object cam.
You can set device-specific properties for your webcam if your device allows programmatic access. These properties vary depending on your device. See the table for a list of the possible properties for a UVC compatible webcam. Your camera may not have all of these. You can set only the properties that your camera supports. To see the properties for your camera, look at the output when you create the webcam object. This example shows the available properties for a Logitech webcam.
To set a device-specific property, use the object name and property name in dot notation as the first argument, and the value you want to set as the second argument. This example sets the camera brightness to the value shown for the webcam object cam.
This table lists the possible properties of UVC webcams. Your specific camera may not have all of these. Your camera could also have mode properties, which are not listed here. See your camera documentation for the list of properties your device supports.
In desktop versions of MATLAB, webcam support is available through the MATLAB Support Package for USB Webcams. For instructions, see Install the MATLAB Support Package for USB Webcams. Webcams are also supported in MATLAB Online. For more information, see Webcam Support in MATLAB Online.
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.
If you are receiving the error message, "Zoom is unable to detect a camera. Make sure your camera is powered on and connected to your computer." when joining a meeting, learn how to troubleshoot this issue.
Zoom regularly provides new versions of the Zoom desktop client and mobile app to release new features and fix bugs. We recommend updating to the latest version when it is available to receive the best video and audio experience.
The 21st century has seen a boom in digital photo manipulation, from Photoshop to Instagram. But the phenomenon goes back to the early 1990s, when digital cameras first became commercially available, and with them the first opportunities to edit your own photos at home.
If you look closely at the crowd, there is a figure holding a blocky white object in front of their face. They seem to be concentrating intently on its reverse, slightly turning it to follow the actions of the moving boxers. This object, the internet agreed, looked rather like a modern camera phone.
Certainly, this was a futuristic digital camera much like those we use today. But what was it doing at a boxing match in the mid-nineties? Obviously, concluded the internet, this person was a time traveller.
The first digital camera was created in the Kodak labs in 1975 by a team led by Steve Sasson. This was a chunky blue and silver box that recorded images on a cassette. It worked, but it was purely experimental. It took another 16 years before the first digital cameras were available to buy in the shops.
Kodak released the Kodak Nikon DCS100, which added a digital camera sensor to a standard Nikon F3 camera, in 1991. It came with a separate digital storage unit that had to be carried around in a shoulder bag to house batteries and a hard drive.
It was always possible to alter a photograph with darkroom trickery, or clever layering of negatives. In the 1920s, for example, Alexander Rodchenko used scissors and paste to assemble impossible collages from multiple photographs.
Before the first consumer digital cameras, it was already possible to create computerised images by scanning physical pictures on a scanner. In 1989, a new machine called a Barneyscanner could be used to make digital copies from 35mm slides and display them on the screen of a Macintosh computer.
Photoshop has made image manipulation more accessible and more convincing. It is now common for photographers to produce a final image by overlaying hundreds of slightly different shots of the night sky, generating an impossibly clear composite view of the stars.
The photograph that our time-travelling photographer took at the boxing match was almost certainly terrible. They were too far away, the boxers were moving around, the camera was fairly poor quality...
I purchased a C270 (in early February) that I use with my Mac. However in Zoom and other software it identifies as USB-camera #3 and the microphone identifies as Unknown USB Audio Device. When I plugged it into a Windows 10-laptop it was immediately identified as HD C270. I tried searching on the Logitech website for a new driver or anything but there isn't anything like that.
The only way I've ever been able to leverage any better behaviour from mine was to get WebCam Settings available from the App Store at $8. There's no free trial, so you'd have to take a punt, but the C270 is listed as supported.
The first thing to consider is what you need your webcam for. For working professionals or office staff, most conference calling software such as Zoom or Microsoft Teams will restrict your broadcast quality to 1080p resolution and 30fps to preserve bandwidth. Google meets goes a step further and restricts your quality to 720p as this is the standard resolution on most built-in laptop cameras.
If you're planning on using a webcam purely for these work-related calls then there isn't any point in buying a powerful 4k model as you simply won't see the benefit. The light and color detection will vary for each model though, so you'll still see a variance in recording quality depending on what webcam you buy.
For content creators such as YouTubers or Streamers, there is a range of powerful webcams available, with some reaching 4K resolution and 60fps for buttery smooth video. These webcams are overkill for occasional use, but with features like a variable field of view (or FOV) and adjustable resolution or and zoom, the extra cash could be a worthy investment to your hobby.
