    @nat – The first thing to check is the webcam driver. Just check if you have the exact same driver version as the others who do not have the problem. If not, make sure to install the same driver.

    @Sam Courtney – So your webcam does not show up in any program that is capable of using webcams?
    If so, check if there is any other video device installed (like a TV card) and try disabling that in the device manager. Also try downloading and reinstalling DirectX.

  2. Hi Kyle I really hope you can help. I have a fujitsu siemens laptop and have been using for about a year. I am a total novice to webcams and therefore i do not know where to even start in order to resolve this issue. The laptop is running MS VISTA. Whenever I go onto cyberlink power dv, its tells me that no camera device has been detected and that I should reconnect and retry. I have had a look at some of the above comments and have tried to follow the advise you have given others. I have checked that the webcam is switched on (Fn+F7), I have tried pressing Fn+F10 (I’m not sure what this is for but you had suggested this to someone else). I have checked the device manager and the webcam is listed in there and there are no yellow warning triangles next to it – however i have noticed that the webcam is not listed when you select to view scanners/cameras. Please help as all your asisstance will be much appreciated.

    @Erik – Disabling and re-enabling devices can indeed help, works great for fixing network device problems as well. Thanks for reporting back your findings.
    Regarding the automation, the obvious answer is to program it. You could use the service control manager and disable/enable the related service, or you could change the registry using the appropriate API. There are some samples around online.

    @IvoBg – The audio recording level is indeed something to check first. Other than that, you should check the USB ports. Try unplugging all USB devices other than the webcam, do not use a USB hub, and check the bios for the USB settings (should be USB 2.0). Have you tried a different chat program, other than MSN messenger? If possible, check YM or Skype to see if the problem is software related.

    @Kyle (author):
    After more troubleshooting, I found the likely culprit: the webcam drivers. Once the problem manifested itself again, I tried disabling and re-enabling each webcam driver in Device Manager (under Imaging Devices). I did not reinstall any software. I didn’t reboot as Windows insisted. I simply restarted H264WebCam instead afterwards. All the cameras worked great again, without having to reboot. Now, I need to figure out how to automate the device driver disable/enable process… (any ideas?).

    Microsoft designed the drivers… go figure.

    Your help is appreciated. Thank you very much.

    @IvoBg:
    This may seem obvious, but have you checked the microphone volume level? Control Panel -> Sound -> Recording Devices.

    Hello, a month ago I bought a camera a4tech pk 720mj, which has a built in microphone. I installed the driver for the camera as well as writing in instructions. My problem is the following, I use MSN Messenger for video chat, after 5 minutes video chat microphone to the camera blocking, on the other side see me but not hear me. Driver for the camera I took it from the official site of A4TECH, but this did not help. I hope you can help me.
    Greetings and sorry for my bad English!

    @Erik – I am obviously not aware of such a specific setup, but have you tried using a (powered) USB hub to make sure the USB power limitation is not an issue? You probably need to check if the hub is USB 2.0 compatible and also check the specific power settings for each of the hub ports as they can very a lot.
    Other than that I would also think it could be the power settings on the USB devices and the overall PC power scheme, but you seem to have verified that already.

    I have 4 Microsoft Lifecam VX-1000 webcams hooked to my PC. They are used for 24/7 surveillance. Each has a USB-to-Ethernet extension cable adapter to extend the cable distance to 50′ (can work up to 150′). In conjunction with H264WebCam, the system works very well. I’ve confirmed it to work for 12 hours straight typically. However, when I come home from work at night, I notice at least one camera is not powered on, even though the software may show an old frame from hours before. If I restart the software, none of the webcams work anymore. Re-plugging the USB cables doesn’t work; if I do, Windows says the devices are unrecognized and that there may be a problem with them. Trying to reset the hubs (which are integrated into the motherboard) via Device Manager doesn’t work. I’ve used the newest drivers as well as older ones. The cabling continuity is good. I’ve tried load balancing by putting some cams on other ports. I’ve disabled selective suspend (power save options). I’m streaming at only 15 fps per camera to conserve USB bandwidth. All these troubleshooting attempts have failed at solving the issue. The only way to resolve is to reboot. After rebooting, everything works great again for hours. I could schedule daily reboots but this is unfeasible as the PC is not dedicated just for surveillance (I game as well). It doesn’t matter what software runs or not, the problem persists. I believe it’s a USB power issue, or maybe the cams ‘fall asleep’ during the evening hours when no motion is detected in darkness.

    My system: Asus M4A79T motherboard, AMD Phenom II X4 955 at stock (3.2 GHz), 8 GB. DDR3-1333 RAM, ATI Radeon 4870 2 GB. PCIe video, USB card reader, Logitech RumblePad 2, 850-watt Corsair power supply. Only 3 months old.

    @Andrew – Is your computer set for USB 2.0 ports? You can check this in the bios.
    Also try updating the drivers on the USB Root hub in the Device Manager.
    Are you using any other USB devices? Try using the webcam only to see if there is a conflict with another USB device (I think this is the least likely scenario, but no harm in trying it).

  10. Andrew says:

    I read your infomative article about webcam problems. How would you solve this?
    Purchased a Microsoft Webcam (lifecam vx5000). Downloaded updated software from their site. At the point of installation where you are asked to connect the device to a usb port, the blue screen of death appeared. The webcam works just fine on another computer whether it is installed with or without the software.
    Thanks.

    @Nicole – If the webcam is working and you have the right driver, there is not too much you can do. In general, ensure the webcam is connected to a USB 2.0 port (and do not use a USB hub), and try changing the image size of the webcam (in the software) if possible.

    Hi! So, I have a problem. I wanted to buy a new webcam for my computer, but my mom found an old one in our house and so Im using that one. I installed it an everything was great, until I realized that it had horrible picture quality. I’ve tried different lighting, fixed the brightness, contrast etc. AND the webcam either doesn’t have a manual focus, or its broken. Is there any way I can fix it without buying a new webcam? PLEASE PLEASE HELP!

    Thanks a bunch,
    Nicole

    @Lawrence – Does the webcam show in your Device Manager and can you use it in other programs? Also check if you have other video input devices (like a TV Card), as you might need to disable them in order for some programs to allow you to work with the webcam.

    @Sunitsa – Try disabling the buitl-in webcam in the Device Manager.

  14. Sunitsa says:

    Hi Kyle!. I just purchased a Logitech quickcam to Skype with, as the built in webcam on my crappy Acer is no good. I installed it the other day and it was working fine, but now my computer will not detect it. It will only pick up the built-in webcam. I know it is working because it allowed me to take pictures when I clicked on the icon in My Computer, but even when I click on the Logitech Quickcam, it still only detects the built-in cam. Please help! I’m away from home at university and I miss talking to my friends and fam :( Any suggestions? I have NO idea how to fix this.

    Hi Kyle

    I Just recently downloaded Windows Live Messenger 9.0 and once i come to use
    the webcam it doesn’t work and wont even let me open the
    audio and video setup. Would you be able to help please?

    Thanks

    @Gerard Scullion – You mean the webcam? Well if it is indeed new, you could try and take it back to see if they can either test it for you or replace it.
    But it is definitely a hardware driver issue. One thing you could try is to right-click the Unkown Device in the Device Manager, and in the popup menu select Update Driver. Opt to browse on your computer and then select from list. In the show compatible hardware, the technika driver should be listed.

    Hi Kyle,
    Thanks for the very fast response. I followe the link, downloaded the driver and installed it on a completely different computer with win xp and still the same message:-

    One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it.

    The location of the device is shown in bold type.

    USB Root Hub (2 ports)
    Unknown Device (in bold)
    Unused Port

    Recommendation
    Try reconnecting the device. If Windows still does not recognise it, replace the device.

    When it is plugged in, the power light on the camera is illuminated so power is getting to it and the driver you suggested for me to download is exactly the same as the one on the CD provided. Could it be a dud?

  18. Kyle says:

    @Gerard Scullion – Have you tried http://rapidshare.com/files/215871588/Technika_H16WC-01.zip ? That driver seems to work for a lot of people.

  19. Gerard Scullion says:

    Sorry forgot to say my OS is Windows XP

    Regards

    I recently purchased a technika H16WC-01 webcam from Tesco (I know, but I needed one in a hurry) and have installed the driver and software. When I plug in the camera, I get a message that one of my USB devices has malfunctioned and when I check the devices it lists the camera as ‘Unknown Device’. I have tried uninstalling, reinstalling, downloading drivers from the Tesco site and everything I know but still the same. I have tried this on my laptop and my desktop and both give the same error. From the Tesco site I noticed a lot of driver problems but none address my problem, can you help please.

  21. Kyle says:

    @Dr . Ruban – The first thing to do is to check if you are both using the same version of msn messenger (or live messenger) and if it is different, make it the same (upgrade one of them).

  22. Dr . Ruban says:

    I’m not really sure what happnened, but I woke up and the computer was off, so I turned it on and it was running some updates. After that I went into devices and the HP Webcam was there, but wasn’t working stiil, the computer still said it had some updates to do and then it restarted itself. After I logged on again, the webcam now works…..I don’t know what happened but it seems to be working!!

    Thank you for your time and help! Your aweseom!
    who knows I might be back for help!

  24. theo says:

    Nothing really shows up when I click properties.
    (Standard USB Host Controller)
    Universal Serial Bus controllers

    But I’ll try the drivers on at the HO site.

  25. Kyle says:

    @theo – That indeed indicates that the (right) webcam driver is not yet installed.
    The link to the HP support website that I gave in comment #342 should allow you to download the driver for the webcam (just pick the right Windows version and check the webcam download).
    I think your webcam is a Chicony model. You might be able to see that in the Device Manager. Click the unknown device and select properties. In the Details tab, select the Manufacturer in the Property list.
