Built-In Webcam Not Working - "Unknown Device" USB Code 43
Dec 31, 2011
I have looked over many, many other forums and threads regarding this issue, but to no avail, have not been able to solve my problem. I'm starting to think that some hardware that communicates with my Webcam could be damaged - but I have not given up hope that this could be solved alternatively. Here are some of my PC specs: OS Name Microsoft Windows 7 Professional Version 6.1.7601 Service Pack 1 Build 7601 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Name BRADY-PC System Manufacturer Hewlett-Packard System Model HP Pavilion dv3 Notebook PC System Type x64-based PC Processor Intel(R) Core(TM)2 Duo CPU T6400 @ 2.00GHz, 2000 Mhz, 2 Core(s), 2 Logical Processor(s) BIOS Version/Date Hewlett-Packard F.14, 07/01/10 SMBIOS Version 2.4 Windows Directory C:Windows System Directory C:Windowssystem32 Boot Device DeviceHarddiskVolume1 Locale United States Hardware Abstraction Layer Version = "6.1.7601.17514"My laptop came preinstalled with Windows Vista Home Edition - I have since upgraded. The webcam was functional with both OS. Also, my BIOS is not updated with the most recent available software (F.15 is available). I had F.15 and downgraded to F.14 to see if that might solve my issue, but it did not. I have tried a variety of different things (clean boot, various installs of the driver, uninstalled all of the devices listed in Universal Serial Bus controllers and restarted), but again, to no avail.I can provide anymore additional information as needed. In the device manager, where it shows "Unknown Device" (which I believe to be the built-in webcam, as it appeared around the same time the webcam stopped working), which is under the Universal Serial Bus controllers, I copied all of the information in the Properties - Details tab. Here is what is displayed for all of the categories:
Code:
Legacy bus type: 0000000F
Bus number: 00000000
Enumerator: USB
Address: 00000005
[code]....

I got a new hard drive for my HP Pavilion DV6T-6000. Installed windows 7 ultimate and a bunch of drivers from HP's drivers section for my computer and I still have this unkown device. It wasn't there on my old drive so something isn't right here.
Location: on Microsoft ACPI-Compliant System
Status: The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver. Hardware ID:ACPIHPQ0004

Since about 1-2 months ago whenever I hooked up my phone (HTC Rezound) to my computer through my USB chord I get an error message saying that it's an unrecognized device and that it was stopped because the device has shown previous problems. I used to upload videos and pictures from my phone to my computer about once a week for months straight and I didn't have a problem with it. Is there any way that I can adjust something in my computer to fix this?

dv6 i7 HP with a webcam that used to work great inside the house. Now, the screen is just about all black except for the dim outline of a light using the HP TrueVision HD cam. Machine came with Cyberlink YouCam 3.5 and I updated it to 5.0 and still same thing. I really don't want to have to use the USB webcam which works fine inside the house. I went to device manager and found the HP TrueVision HD driver and updated it and it says that I have the latest driver. Maybe I should delete this and re-install? I went to an SSD which runs well but according to them it messes up the entire system and I am a bad customer. The problem existed before the SSD and I really do not wish to deal with HP tech any longer. BTW the cam shows up outside so something is screwy and I cant put my finger on it. I have adjusted all the settings up down and everywhere in between then back to default which always worked well.

The built in webcam on my Acer laptop stopped working. When I tried to use it, a message popped up that said I needed to update it. So I let the computer update. After that my computer wasn't able to detect my webcam. So I uninstalled it and tried to reinstall it from the internet but it still doesn't. It installed but when I try to open it, it says "Camera not found".

I have a Dell Vostro 1500, running 32-bit Windows 7. It came with Vista, but I upgraded to Windows 7 a couple months ago, which I think is causing the issues I'm experiencing. According to whoever I'm speaking with, the sound for the microphone built in to my webcam fades in and out and gets really loud randomly. In an attempt to solve this, I bought an external microphone which also does not work. The sound driver is the SigmaTel High Definition Audio CODEC, version 6.10.0.5614. When I tried to update it through Windows 7's update driver software it says I have the best version for my system, but I still suspect that this could be what is causing the problem.

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.
Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

So I tried formatting it and it saidWe couldn't create a new partition error:0xc983c160] <- googled it and no results at all.I went to cmd and tried to convert mbr to gpt manually.Gave me: Virtual drive error:This specific drive cannot be converted. Example: dvds and cds cannot be converted It is not a virtual machine,it is the real hdd.

I've been having issues with several computers now. All of them Windows 7 Professional 32 bits. The error they're having is the same on each PC: explorer.exe fails and restarts after clicking Ok to the dialog.
Code:
Level: Error
Source: Application Error
Event ID: 1000
Faulting application: explorer.exe, version: 6.1.7601.175xx, time stamp: <changes>
faulting module: unknown, version: 0.0.0.0, time stamp: 0x00000000
Exception code : 0xc0000005
I already ran viruschecks and spywarescans. Clean booted. sfc'd. Uninstalled all updates since the week previous to the first error. Created a fresh new profile for the user. Disabled all non-Microsoft shell extensions. Reinstalled Windows. and non on them had made a difference.
The oldest issue is november 6th (there's not a single instance of the error before that date); since then, the issue is happening at least once a day but more like 5-10 times a day. I ran Windbg and for almost all errors it points to "fundisc" module as the culprit, although i don't know what piece of software would be using it. The only updates they had installed are security and critical updates via WSUS.

I really apologize for the vague title, all I can say about these BSOD's are that they've occurred with increasing frequently over the past week, and are seemly random. I have noticed that they happen more often whenever Shockwave crashes in Chrome and does not recover. I've also noticed that I get a BSOD whenever I attempt a full scan using Spyware Doctor. Otherwise, these BSOD's really just happen wherever, whenever.

My webcam doesn't really work when I use ooVoo or Skype... for example, I have just downloaded ooVoo and I was told to check my webcam availability and all that, so when I tested my webcam, it didn't work. I viewed the "devices and printers" section, and clicked on my webcam icon and looked at its properties and checked its device status and it said "This device is working properly". I thought the problem was ooVoo but then I used Skype and Facebook webcam and still my webcam didn't work. I'm using Windows 7.

When I first bought my laptop installed with Windows 7 Home Premium 64 Bit, the built in webcam was appearing in 'computer' but when I installed Windows 7 Ultimate 64 Bit, it disappeared from 'computer'. My laptop is an Acer Aspire 5552 and my older sister also has an Acer laptop with a built in webcam and also not appearing in 'computer' and I think she is still using the default installed operating system because hers is Windows 7 Home Premium 64 Bit And I don't think she would choose to just format and install the same exact OS right out of the box...I called Acer tech support and they say they can fix the problem remotely but for a fee of almost 100$ which I dont have.
by the way it dont actually really matter if it works or not because I have my laptop connected to a 52" 120 hz full hd lcd hdtv via hdmi cord so the laptop is closed and upside down with the battery taken out ...on my fireplace mantel...all i use it for is to download 1080p bluray rips and watch 1080p bluray rips via 2tb external harddrive
And the driver for the built in webcam does show up in device manager without any problems there and it is also up to date

I got a new Dell Studio XPS 13 laptop a week or so back, loaded Windows 7 RC and everything worked fine after a bit of fettling here and there. On Tuesday or Wednesday I had a problem where the laptop locked up while using a Logitech USB Radio mouse. Thinking the mouse caused the lockup, I disconnected it and have been using the touch pad since and no lockups. So far so good.
Then today I plugged in a set of Logitech USB headphones for Skype and I got an 'unknown device' error. I tried with other USB items, ADSL modem, memory stick, all had the same problem on both USB ports and nothing I did would solve the problem. Much googling and a search of this forum again came up with nothing I could use.
I then had a flash of brilliance - I figured it must have been the mouse that started the problem when the laptop froze and somehow something was blocking the USB useage. I plugged in the mouse whereupon it loaded up the software and worked fine, and now everything else loads up and works OK too!
I can't explain it, I'm just a programmer and don't really understand computers but if it helps anyone else in the same frustrating situation, there it is.
