Thinkpad L412 Integrated Camera and USB Controller Not working

My Integrated Camera has disappeared from the device manager listing, and "USB not connected". Further, the USB Controller has an "Unknown Device" with no driver. None of my USB ports work beyond power. I cannot find any drivers or other way to resolve. Any suggestions? 
Thanks in advance for assistance!!!

Grab the latest chipset driver package from Intel's download center, and run the setup EXE with the -overall switch.

  • HPDV6 6c04sa - HP truevision HD camea and usb ports not working

    My camera is not working - there appear to be no drivers for it through the website for re-installing, and none in HP recovery and the copies of the original drivers loaded on the computer.  Cyerlink you cam does not install a driver.
    How am I expected to be able to re-instal a driver when there is not driver for it?
    Secondly, there is no information on the camera provided in the laptop.
    USB ports on the left hand side are not working.
    Finally - there is a mysterious Q drive which also appears not to function.

    Is the HP TrueVision HD internal webcam usb based?

  • Camera and flashlight does not work

    My camera and flashlight will not work after the ios 7 upgrade. I have rebootd and completely wiped out my iPhone and still no camera or flashlight. I have seen where others are having the same problem but no answers.

    I had the same problem it's definitely a software issue because the camera would sometimes work in camera apps but now I could not switch cameras at all.
    I may have found a solution of course I probably won't get credit for thanks to Apple.
    I believe the problem arises from a bug when the camera is used in lock mode, try restarting your phone with the home and power button. Then open your camera in locked mode and set the flash to auto. Maybe take a few pictures, switch the camera back and fourth, turn HDR on and off, but make sure the flash is set to auto before you unlock the phone. Heck even try playing with the flashlight.
    After I did this in locked mode to my surprise my camera and flashlight are now fully functional after I have unlocked it with the password. I'm not to sure what triggered this bug but when I first got iOS 7 and played with my phone some how I unlocked the lock screen without putting in a password. Just by using the camera and the notification and control Center, I unlocked the phone which might of triggered the bug.

  • Touchsmart TX-2 fingerprint scanner and USB ports not working

    Hi everyone,
    Please forgive me if this is in the wrong spot.
    Just sent my laptop (Touchsmart TX-2 1015au) off for a warranty fix - told them the USB ports weren't working on Windows 7, 64 bit. It came back wiped, running on Vista 32 bit and.....with the USB ports not working.
    I figured I'd try to get it working because I need my laptop for uni and can't send it back right now. So I clean installed Windows 7, 64 bit again and its still not working. Did the standard open device manager and uninstall everything under the usb tab. All that has resulted in is causing the fingerprint scanner to stop working (being told that it is not connected) and still no working USB ports.
    All advice really welcome and very much appreciated!
    Thanks in advance

    Hi:
    Should be no problem to get W7 32 bit to work on that model.
    Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
    Your model uses the Intel HD graphics driver only.
    The first driver you have to install is the Intel chipset installation utility and then reboot.

  • Webcam and usb drive not working--possible hardware issue?

    Hello,
    I recently purchased a Lenovo ideapad U510 with Windows 8. I bought it as a returned machine but the Staples employee didn't know why it had been returned and thought it was just because the buyer didn't like Windows 8. When I first set it up I kept getting an error message that my usb device was not recognized, even though I had never plugged anything in. As I was leaving the country, I dismissed the issue and decided to deal w/ it when I returned to the US, since my other usb drives worked fine.
    However, later my integrated webcam stopped working as well. It worked one time when I used Skype but not after that. I checked online forums for possible solutions, and most said I needed to download an updated driver. I didn't think this was the issue b/c when I went to device manager and tried to update my driver for the easycam, it said I already had the most up-to-date driver. I have uninstalled drivers, downloaded and re-installed drivers, and even refreshed my computer, all to no avail.
    Here are the error messages I receive:
    In device manager>view>show hidden devices>imaging devices>Lenovo EasyCamera, device status says
    Currently, this hardware device is not connected to the computer. (Code 45)
    To fix this problem, reconnect this hardware device to the computer.
    When I try to run the Bison setup: Lenovo EasyCam has not found! 
    When I try to run the Chicony setup: Setup failed! Please Plugin camera and install driver again!
    So, I'm thinking it's not a driver issue, but I'm not a techie and don't know what else it could be. Wondering if the usb problem and webcam problem are connected. Found another forum post that said maybe the webcam is not connected to the motherboard...suggestions?
    Thank you in advance for your help.

    I am certain it is a hardware issue from the problems youre describing. I would contact Lenovo. They may try to have you purchase their "software" support, but don't let them. I had wifi issues and they tried to make me spend $90 because I was too lazy to figure it out on my own.
    Make sure when you're calling support that you tell them that you restored to factory default and before you send your computer in, back up your data. Also tell them that it's a new computer and you do not want to pay for shipping... They will most likely comp you shipping in both directions.

  • HP Pavilion 17 Notebook PC (Windows 7 Ultimate x64) USB controller not working

    I am having problems with my HP Pavilion 17 Notebook PC (Windows 7 Ultimate x64) Intially Windows 8 was installed but I got windows 7ultimate for it and now I'm missing the drivers for it.
    I don't know how to fix this problem, I have tried everything. I downloaded an program called DeviceDocter and it downloaded the thing but then an error saying. Your system does not meet the miniumum requirements for this update. Update has been cancelled. (9996). It says AMD USB Controller Driver. It should work on my computer since it's Windows 7 Ultimate x64. Please help me fix my ports. Just my 2 ports on my left side of the computer isn't working. The right side of the computer port is working.

    Thanks for the help, but I found the program to fix it. After searching for hours. I stumbled upon this link and it finally worked and the unknown device was only my headset and the other one I just updated by making it search online for the software. Here is the link for other people to use to fix their usb port problems. - http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?javax.portlet.begCac...

  • Installed Windows & 32 Bit But Drivers and USB ports NOT WORKING.

    I bugh an HP Pavillion TS 14 Notebook that came preinstall with Windows 8.1 64 bit which I hate so wiped the drives and installed Windows 7 32 bit and now I have a big problem.  None of my network drivers work and the 2 uSB ports where I plug my mouse and other SB hardware in no longer work. 
    I did a back up of the SW Set up file that has all of the HP dvers for my laptop but both the network and video divers won't install. And When I try to install the drives I get the eror message saying they are not compatible with this version of Windows.
    I have loked on the HP website under my laptop model which s as above but HP don't do drivers for Windows 7 32 for my laptop. And I have looked on both the Realteck website for both the Realteck ethnet and Realteck wireless network drivers but none of them work or install on my operating system. The video drivers Intel don't work either. So I am really stuck a I cannot go back to Windows 8.1 as though that 32 bit Windows 7 would work on my laptop but most of my drivers are not compatible with the operating sytem And I don't want to install 64 bit Windows as I like 32 bit.
    The drivers that are not working on Windows 7 32 bit are:
    Realteck RTL8188EE 802-11b/gn witeless lan
    Realteck ethnet die and
    Intel High definition graphcs driver 
    Which don't work at all on Windows 7 32 bit as they are 64 bit only drivers.
    So can you please post me a link bth the network and Intel graphics drvers that work with my laptop. As I have tried lots of different Realteck and raphics drivers for Window 7 but NONE of them work on my system. And None of my USB ports are working either. So how do I solve this problem?

  • Camera and led light not working after IOS 7 update on iphone 5 help please!!

    After I installed the update my led light won't work for the flashlight and my camera doesn't work either. Only the front facing camera works. Any suggestions?

    thanks for the suggestions, i tried the ideas you suggested but i dont even get a camera showing for the rear camera, i also noticed the torchlight no longer works.  i did all the steps but no luck.
    So I took my camera to the genius bar this weekend as well as walking through various steps with the apple guys in ohio support over the net. 
    With the guys at the genius bar, after i insisted that it must be software as the rear camera stopped working only after the softwre update, they continued to assure me it was hardware and talked me into letting them replace the camera,  they then took it to the back and tried fixing a camera and 30 minutes later came out and said the rear camera is no longer being detected and wanted me to replace the motherboard for yet more money.  im glad they didnt charge me for the new camera though as it still didnt work.
    anyway the motherboard idea i rejected as it was just 2 months out of warranty and had only stopped working the day after the release of 7.0.2, so im going to wait until the next few releases to see what happens, as i dont believe for a second its hardware.  i expected a stock answer from apple and its exactly what i got even after my explanation of how it was working the day before the release.  not overly impressed with the whole process.
    i wanted to back down to 7.0.1 to confirm the camera still works but they said no chance so i cant even see if it still works ouside 7.0.2.  anyway will update if i get any further progress.

  • IPhone 4 camera and photo application not working!!

    My iphone 4 camera and photo applications do not work anymore. When I tried to take a picture, the camera froze. I turned off my phone and when i turned it back on, the app will load, but when i tap to take the picture it returns to the home screen. The picture library application does the same thing. I try to load my picture library and when I tap to open it, it returns to the home screen.
    I have tried turning it off and on multiple times and also turned it off for an extended period of time and it still doesn't work. Any suggestions on what the problem could be or possible ways to fix this would be greatly appreciated.

    Tap Settings App>General>Reset, near bottom of list>Reset All Settings. If this does not help you could try a Restore with iTunes, and when asked at end Set Up as New. If this does not help and you have Warranty or AppleCare Coverage take iPhone to Apple for resolution.

  • Both internal and USB mics not working

    Hi there, all. Long-time lurker, first-time poster. Starting last night, I have been having issues with microphone use on my iBook G4. Neither the internal mic nor my USB headset mic (Altec Lansing AHS302USB) are accepting input.
    The internal mic's failure doesn't surprise me, as I have heard about the delicate nature of the wire connecting the internal mic from its position on the display down to the main computer. It's the USB mic that confuses me, since USB mics are what everyone seems to recommend that people use when the internal mic is on the fritz (thanks to other mics not working with Mac due to the line-in thing). Also there is the fact that I have used this headset with this computer for over a year with no significant issues until now, with both mics simultaneously failing.
    There doesn't seem to be a problem with the headset's wires; I am still able to hear audio through the headphones quite well, and when I load my audio recording program (Audio In) and Sound Preferences, I can see the occasional blip of sound recognition when I move the USB adapter portion around in the port. These blips even occur when the pink microphone jack and headphones jack are unplugged from the adapter, so this suggests to me that the problem lies not with the wires, but somewhere in the USB adapter, port, or the computer itself.
    I'm leaning toward the computer itself, since it just seems odd that both mics would just happen to stop working at the same time. That and the fact that audio output still works through the headset, and the USB ports work fine for other USB devices such as my external drive and iPod.
    I have tried restarting, resetting the PRAM, and repairing permissions with Disk Utility. Nothing's working so far.
    Does anyone have any idea what could possibly be wrong?
    For reference's sake, I took a recording of the sound that results from jiggling the USB headset adapter in the port. It's very quiet, so you may need to turn up the volume a little bit to hear it. Again, these are the ONLY sounds that the mic is able to pick up currently.

    Just to chime in here - I wonder if it's down to the software: I've recently updated to 10.4.10, and the internal mic seems to have stopped working.
    One positive effect of the change to 10.4.10 is that my Griffin iMic no longer flips to 8-bit, 22khz recording when I plug it in.
    Having said that, I really like to get my internal mic back up and running again.

  • Back camera and power buton not working

    hello dear ,
                  i have problem in my i phone 4,s camera and power buton . how can i replace it

    If this does not resolve the issues, take the device to Apple for evaluation and possible replacement.

  • Why is my Intel iMac restarting randomly and USB keyboard not working randomly?

    My intel iMac has been randomly rebooting itself without any error messages.  It also seems to coincide with the keyboard (USB) not working, but not always.  At first, it seemed to happen right after waking the computer from sleep, but now it happens when I am just sitting at the computer about once or twice a day.  For now, i have temporarily removed all external devices (except time capsule) and disabled any bluetooth or iTunes synch'ing over wifi.  I have also disabled all power management features.
    I've tried different keyboards and resetting the SMC.  Could bad memory cause this?

    Could be anything from a loose power cable, to loose or bad RAM module.
    1. Check all your power connections, including the mag connector on the back of the iMac.
    2.  Reinstall the RAM modules, as per > iMac: How to remove or install memory. When installing new or reinstalling RAM, be sure to push firmly on each module with both thumbs to insure that they are fully seated in the slots.
    Then if it is still acting up...
    3. Run the > Extended Apple Hardware Test

  • My camera and facetime are not working

    The icons for my camera and facetime disappeared. When checking the internet for help, some said to go into "Settings" then " Restrictions" and then enable the camera and facetime. I see these 2 items and they show that they are turned off. But when I try to turn them on nothing happens. I tried other switches such as Safari and it turns on and off. Can anyone provide some help? Thanks Randy
