• The Device Manager has yellow exclamation on other devices.

  The Device Manager has yellow exclamation on other devices. Peripheral unknown bus controller universal series (usb) 1) 2 SM bus controller) 3). No driver installed. No driver found on driver updates. Not causing no problem but I don't know what could be the devices.

  Thia article gives some indications - http://techforcommoners.blogspot.co.uk/2009/10/how-to-identify-unknown-devices-in.html its worth a read to see if it helps.

  Basically, it starts by looking for the hardware id in Device Manager and it enter the PCIDatabase to see if it can find all matches. It is sometimes useful in such cases.

  Another place to look is 'information system' (enter 'system info' (without the quotes) as the research) and look in there for pointers, esp in "components - peripheral problem."

• T61 - no sound - Audio on High Definition Audio Bus with yellow exclamation point device

  Hello

  I don't know when it started, but suddenly my T61 has no audio/HiFi. I checked the Device Manager and saw the device on High Definition Audio Bus Audio with question mark (large) yellow with yellow exclamation superimposed on it. On Lenovo's Support site, I downloaded the 7ka114ww.exe, hoping to remedy this device to uninstall it reboot and re - install using the downloaded exe, but anything will do.

  Any suggestion or help is really appreciated. Thanks in advance

  PS. I also see the basic pop up system device after a reboot and ask to be installed? This pop-up had been there for some time before the sound/sound has been lost.

  Hi and welcome to the forum!

  What operating system do you use?

  When you say that you have installed the driver, do you also go to C:/drivers /... to run the .exe steup? The second Setup program must be run to install the driver correctly.

• The camera driver won't install; all portable devices under Device Manager have yellow warnings

  Windows 7 64 bit

  All portable devices in Device Manager have yellow warnings.  I followed the directions of the driver reinstall paragraph each device status, but nothing has changed - warnings remain. Although warnings have existed for some time, I had no problem with the computer read maps or the connection with devices until recently, when a Canon camera wouldn't connect via USB or wireless because his driver would not move.  (The camera connects to my other Windows 7 64 x computer.)

  Running sfc/scannow a couple of times have mounted several corrupted files that could not be repaired: WUDFPlatform.dll, WUDFrd.sys, WUDFPf.sys, MsftWdf_User_01_11_00_Inbox_Critical.Wdf, WUDFSvc.dll, WUDFHost.exe, WUDFCoinstaller.dll, WUDFx.dll. The scannow report also stated that the same files under ' Package_1_for_KB2685813 ~ 31bf3856ad364e35 ~ amd64 ~ ~ 6.1.1.11.2685813 - 2_neutral_GDR ' were also damaged.  Each file corrupted in both sets also said 'hash mismatch' at the end.  I tried to replace the corrupted with good files, but Windows won't allow.

  KB2685813 was apparently the above Windows Update. He appears twice on the same date (in November 2012) in the list of my computer for updates.  I tried to uninstall it, but get the message that the uninstall failed.

  Wudfsvc service is set to automatic, but it is not started.  It displays the message "unable to read the description. "Error Code: 193. In the Manager of tasks, under services, its status is "stopped".

  Any suggestions?  Thank you.

  Thank you.  I solved the problem more simply.  I learned live to access corrupted files (TrustedInstaller owned files and blocked any changes to them) and replaced by vouchers.  Now everything works.

  There is information online times how to change the owner of TrustedInstaller or anything else and then restore ownership to TrustedInstaller.

• Minor problem with the New Installation of Windows 7 on my Inspiron E1705/9400 - two entries for "Base system device" under "Other devices" with yellow exclamation point

  Hello

  First of all, let me tell you about my system.   It is of a laptop Inspiron E1705/9400 with the Core 2 Duo T7400 processor clocked at 2.16 GHZ.   It has 2 GB of RAM and a hard drive on the Hitachi Travelstar nine 500 GB (7200 RPM).   It also has the GeForce Go 7900 GS video card.    Previously, it had Windows XP Professional (32 bit) and worked well.   But, I have three computers in my home and Home Office and would they work better together on my wired home network, so I'm upgrading all three to Windows 7.   My two desktops (a Dimension XPS 420 and the other Dimension XPS 430) seem like they will be no problem to upgrade to Windows 7.   But, this laptop was not on the list of Dell Windows 7 compatibility.   However, the Windows 7 Upgrade Advisor that I have downloaded and run seemed to say that it was OK to do a clean install of Windows 7 32-bit and he had only a few minor issues, where it says search the drivers updated from the manufacturer.   Initially, the laptop came with a 100 GB hard drive.   For my use, which becomes very small, so I decided to get the exact same 7200 RPM drive 500 GB size.   This will allow me to do a clean install of the 32 bit Windows 7 OS on the new hard drive and not have to wipe the old disk to do so.   I can just keep the old HD and paste it back whenever I need to get something out of it.

  So, here's my minor problem.   After the transfer of some elements off the coast of the old hard drive, I installed the new 500 GB drive and installed a cleaning of the 32-bit version of Windows 7.    I'm happy to announce that I have not had virtually no problems with installation and everything seems to work fine.   He seems a little more zippy than before and I have not met so far that doesn't seem to work.   I went through most of features and almost everything is superb.   But there is a minor problem, showing in Device Manager.   At least, I think it's a minor problem, but maybe someone can give me feedback to know if she is or not.

  In the Device Manager list, there is a category called "other devices" now and the icon shows a little white circle with an exclamation mark.    When you expand this category, you see two identical entries that say "Base system device" and the icon has a yellow circle with an exclamation mark inside.     I know from experience that it is not a good thing to see items in the device manager that have a yellow circle with an exclamation point.   I clicked on both of them and neither one really tells you what the device is, or who did what is site you would go to a driver.    On the general tab, it has the following information:

  -Device type Other devices

  Reference of the manufacturer- Unknown

                       Location     -         Bus PCI 3, device 1, function 3

  
  

  Under device status, it says the following:

                         The drivers for this device are not installed. (Code 28)

  There is no driver selected for the item or a set of device information

  To find a driver for this device, click Update driver.

  Each of the entries seem to be almost the same thing... but not exactly.   The other has the location

  list PCI Bus 3, device 1, function 2... instead of function 1.   This seems to be the only difference.

  I tried the button to update the driver, but that doesn't seem to work.   No matter if you say it looks like your

  computer or to look for a new driver from the internet, it does not find anything.     As I said at the beginning,

  the system seems to work very well... but, given that I don't know what this device is or does, I might be missing something.

  He drives me crazy just have these yellow circles with exclamation point hanging out in my device manager.

  I could really use some help here.    Any ideas or help would be greatly appreciated.

  Thank you

  BTW, I just downloaded and installed the driver pack from this ftp location and it worked, even for Windows 8.1 - 64 bit.

  Thanks Steve!

• P 8470 & HP HP 8440 P: upgrading to W10 Pro 64 bit / device Reporting - unknown device manager

  I have recently upgraded to Windows Pro 64-bit 10.  Machines involved are - 8440p & 8470p running W7 Pro 64-bit.

  The Device Manager shows an unknown device - ACPI\HPQ6000\3 & 33FD14CA & 0.

  Could someone tell me what this is in reference to.  Perhaps point to a driver that I could update.

  Thank you / / Jeff

  You are the very welcome.

  The reason why you don't see the driver is because most of the drivers are missing in support pages, which have not worked directly for HP split into 2 companies from 1 August.

  This is certainly the driver you need.  If the version of W7 works, I can't say.

  See if it works.

  FTP://ftp.HP.com/pub/SoftPaq/sp59001-59500/sp59282.exe

  If this driver does the same thing...

  Go to Device Manager and click on the unknown device of 6000 who need pilots.

  Click on the driver tab, click on set to update driver.  Select her browse my computer for driver software option, then at the bottom of this window, let pick me from a list of drivers for devices on my computer.

  Click on disk and go to C:\SWSetup\sp59282\accelerometer and select the HP Mobile Data Protection sensor and see if the pilot goes like this.

  Here's a partial copy and paste of the accelerometer installation information file.

  As you can see the device is supported by the driver.

  But it's the most recent driver is there, I know.

  [Manufacturer]
  Mfg % = HP, ntamd64

  [HP.ntamd64]
  DeviceDesc % = HPAccelerometerDriverInstall.ntamd64, ACPI\HPQ6000

• Qosmio F30-112: CONTROLLER of BUS SM with yellow exclamation point

  Hello

  Recently I reformat my win pc XP MC using the recovery CD, but I saw on the Device Manager CONTROLLER of BUS SM is to have yellow question mark.
  How could I solve this problem?

  Some time my pc froze (work stoppage) so I have to restart my pc.
  Is it because of the sm bus controller? I try to click on update, but there is a message (the hardware was not installed because the wizard cannot find the necessary software)

  An organization can guide me how to fix it?

  Thank you
  rtmasagca

  Hello

  In your case, I would recommend to day/reinstall the driver!
  F30 - 112 is a part of the PQF30E series.

  SM bus controller can be the SD card reader.
  That's why I recommend that you download the Texas Instruments Flash Media Driver v 2.0.0.4 Toshiba page pilot European and install it again.

• vGPU, being not recognized in Windows (but visible of all kinds in the Device Manager with!)

  Hello

  I hope I found the right place to ask this question.

  Im trying to configure with network cards K1 on esx vGPU 6 and windows 2008 R2.

  I managed to get the GPU passthrough works fine but I want to continue vGPU (last n more)

  That's what I've done so far.

  Installed esx6 on Cisco UCS C240 M4 (CPU value high performance max flow and mem)

  installed the last grid VIB Manager

  
  

  i.e. esxcli vib software install - no.-GIS-check-v /vmfs/volumes/ISO/vib/NVIDIA-vgx-VMware-346.27-1OEM.600.0.0.2159203.x86_64.vib Result of the installation: Message: operation completed successfully.

  
  

  NVIDIA-smi reports 8 x 4gig GPU

  
  

  Using the vmware webclient service, I create a virtual machine and assign it a profile of vGPU (180 in this case). He tells me that I have reached the maximum number of devices of this type (google was not helpful about this message).

  
  

  In the vSPhere console, I see a PCI Device 0 added to the new virtual machine, it is said he has not supported with a note saying "this virtual device type is supported but support it is not supported on the current host... »

  
  

  When I install windows on this virtual machine, I get a yellow! on the standard VGA graphics card with error device cannot start Code 10. Any attempt to install NVidia drivers cannot complain that it cannot detect the graphics hardware.
  

  
  

  The thing is, I'm sure I got this work before, but now it feels like Ive hit some limits as suggested by the message "maximum number of devices.

  
  

  I tested using vmware 5.5 and 6.0 tools
  

  
  

  Any suggestions aside from just rebuild again?

  Hmm, it seems that the comment on the unsupported PCI device may be an effect to use instead of the web client vSphere client. I created a new virtual from Windows 7 machine and used the provided in the package VIB of nvidia driver and it worked. In the console PCI device said still not taken in charge. I will try to update the driver in our w2k8 server now.

  Update: Yes, it seems that I used the wrong driver package. It seems that I can have tried to use another driver which I suppose was for use with vSGA or pass through.

Its happened to me before and recently started happening to my cpu. I did a FRESH install of windows to see if it can help, but it didn't.

Whenever the yellow icon pops up that I have troubleshoot and it indicates the default gateway was unavailable and that fixed it, then I have internet again for about 2-5 minutes and it does the same thing. Ive never had this problem on my cpu and the network has not been changed or anything, so I don't know what that the * could cause this. I literally wiped everything on my cpu and then do a system image to restore too. Ive been messing around with the registry, deletion of things here and there missions that I read, but only thing that happens is losing internet alltogether and must restore from system image. I'm really running out of ideas. Help, please. I have an adapter netgear wn311b wireless pci-express with the latest drivers.
