I have been running in to an issue lately with a Latitude E5540 laptop.
The specs are:
Intel i5 cpu @ 1.9 ghz
4 gb RAM
x32 Windows 7
In my device manager it says that I have an unknown device and there is the warning symbol next to it. When I go to update the drivers it says that it can't find any drivers (I am connected to the Internet). I looked at the hardware ID and noticed that it was APCISMO8810, I then proceeded to research the driver, which I found was the ST Microelectronics Free Fall Sensor Driver. I also know what it's primary function is.
The issue I keep running in to is that I have uninstalled the driver, and tried to re-install the driver from the Dell downloads. However halfway through the process the install wizard tells me that the most recently updated driver from dells site is older than the driver I currently have installed. (even though it says there is no driver installed)
I installed Windows 7 64 bit on a Dell E4200.I had two yellow exclamation points in device manager for unknown devices.
PCI Serial Port PCI Simple Communications
I went to Dell support site and to the drivers and downloads page for my Service Tag.Under the Chipset section there is an Intel driver for AMT HECI. Installing that driver solved the PCI Simple Communications item.
Also under Chipset there is an Intel driver AMT SOL. I installed that driver but the PCI Serial Port was still showing Unknown with the Yellow..In my case I had to then manually Update the driver as follows:
Open Device Manager > right click on PCI Serial Port and choose Update driver > choose Browse my computer and browse to the driver folder for the AMT SOL just created when you downloaded and installed the driver mentioned above. Location for me is C:DellDriversR279202.
had a pre-installed vista on my 6680ej and everything was fine, till i upgraded to windows 7. now i have an unknown device in device manager called Intel(R) ICH8M LPC Interface Controller - 2815 and i can't seem to find drivers for it.
recently purchased a Inspiron 15R 5521 from Dell Australia and took me a few weeks to install and setup the the system the way I want.
Today, I tried to enable bluetooth but the slider won't move to On mode, so I checked Device Manager and Bluetooth device was labeled as Unknown device.
So I checked my service tag numbered driver updates and there's a Intel Centrino Advance-N 2230 15.5.6.48 A02 driver update, so tried updating to that driver. But it returned device not configured correctly and prompting me to reinstall driver. Reinstalling driver fails with code 1 error.
Maybe something physically wrong with the Bluetooth side of the hardware ??? Anyway to confirm such without doing a full factory image restore as it took ages for me to setup the system the way I want !
I've tried, uninstalling the bluetooth device from device manager and restarting Win 8 and reinstalling device via hardware change detection Tried uninstalling Centrino driver and installing previous version of the driver
below are screenshots of what I see

I,ve tried this link, but it doesn't work: [URL] .....
2. And do I need to install some drivers for my laptop's motherboard/chipset AMD A76M FCH ? I couldn't find driver for it, so maybe it is pre-installed with Windows 8.1?
I have installed Windows 8.1 on my laptop HP pavilion G6 model 2241sa. Almost all drivers were installed automatically. Additionally I downloaded from HP support site all drivers for similar model (2241nr).
I installed everything one be one. All works BUT ONE device is not recognised... Here are some details of it:
It says Unknown device (in Other devices group) with yellow exclamation mark. Location - on PCI Express Root Complex. bios device name - _SB. PCI0.ACEL, hardware ID - ACPI VEN_HPQ& DEV_0004. That's all i have about this device.
How to establish which driver I need and for which device?
I have the latest Bios update and the laptop seems to suffer from wanting to boot properly on 1st attempt. Sometimes it will take up to 10 tries before it boots up.
Symptoms: Dell logs goes half and the machine freezes, sometimes it will just be stuck on the logo and not boot at all.
A brand new laptop with this problem is REALLY frustrating. I guess I have to log a call with them to get them to fix it?
I got my new laptop today, and got rid of the installed Dell Crap and installed my Windows 7 Ultimate 64-bit.
Now under my Device Manager I've got two issues:
Base System Base System
I contacted Dell, they said they won't support my laptop since I don't have their operating system on it. All I want to know is what drivers I need. I can't believe they couldn't let me know.
I regularly find that, with a single keystroke, my brand new Dell Latitude e5540 laptop randommly produces 2 spaces (most often) and double letters (sommewhat less often than the doubled spaces, but consistently and predictably). The faster I type, the more oftenn the errors occur... I have found it to be an issue of how hard I strike the keys. The keys controlled by my dominant right hand are most often affected whereas those controlled by my pinkie fingers NEVER have been affected.
I amm only one of many employees at my place of work who all are experiencing the same problemm. I have asked repeatedly for Dell to let me know the extent of this problem and whether they have a recall of this model (which, as far as I can tell, is pervasive with this particular mmodel). My persistent questions have never been answered by Dell, despite numerous contacts with 3 different agents.
P.S. If you notice double letters where there should be single letters or extra spaces in this e-mail and this post scrippt, please read on for the reasonn: I am using the brand new Dell Latitude e5540 computer our school system recently purchased to write this e-mail. I have simmply givven up editing my typing... you're getting the spontaneous errors caused by this computer so you can see for yourself and hopefully to motivate Dell to fix the problemm soonner, rather than latter.
IMPORTANTLY, if you are having similar problems with YOUR BRAND NEW Dell Latitude e5540 laptop you specifically will NOT have tthese problems if you use an external keyboard... it only occurs with the laptop's built in keyboard) PLEASE send me your servvice tag (S/N) nummber from the bottom of your Delll LLatitude e5540 computer and I will include your commputer in my conntact with Delll about this problem. (It is a problemm of this particular model... I have never experiennced this before with any other computer).
I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
Device manager lists the device in question as follows: Device instance path: ROOTSYSTEM001 Hardware Ids: rootiwdbus Device stack: DriverPnPManager
I have just installed Windows 8.1 x64 on my Lenovo E330.
I downloaded drivers from the website, and installed all of them. But after that there's one device listed as Unknown in device manager, and I can't figure our which device it is.
Hardware ID is {48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver, so that doesn't identify the device.
I just bought a B590, model 20208, with, i3-3110m, 500GB HDD, GeForce 720M.I installed Win 7 64bits, but in Device Manager, before installing all the drivers appeared Other Devices an Unknown Device with thise details: code 28, Device type: Other devices; Location: on Microsoft ACPI-Compliant Embedded Controllert . After installing drivers, the problem persists.Another problem was with PCI express but resolved with Intel Management Engine Interface drivers.Other problem resolved was with the GeForce 720 M videocard; wasn't recognized but resolved with the last driver from GeForce site. the last problem remained it's The Unknown Devices.
Dell Latitude E5540 keyboard and touchpad freeze. Sometimes when pressing Enter the keyboard and touchpad freeze but the laptop keep processing, so I need to restart my notebook to have the keyboard back....
Specs:
8GB DDR3 500GB HDD Windows 7 Pro x64, even with the preinstalled Ubonto have the same issue.
I have a Dell E5540 laptop and the touchpad is working fine, except that it won't zoom or rotate. All other gestures work as they should - scrolling, three finger-gestures, ...: no problem. But no zooming or rotating.
Both options are of course enabled in the Dell Touchpad settings. I have removed the touchpad from the device manager and reinstalled it with the most recent drivers, but to no avail.
I think it's a software problem since scrolling with two fingers works without a problem?
I have an HP Pavilion dv5-1183cl that has been upgraded from Windows Vista to Windows 7 Ultimate (32bit) and I have some issues.I have four errors showing up in my device manager, three Base System Device and one Unknown Device, and I don't know what they are or where to get the drivers (since I don't know what they are). Additionally, the battery will not charge (there does not appear to be anything wrong with it physically). I am wondering if the below errors are related to the battery issue. Below are the hardware IDs for each error entry.

Can anyone please advise me what the "fix" is to get rid of a "? USB Device" indicator in the Hardware Details of a Latitude D630?
It seems as though quite a few people have reported this but I cannot find a definite fix.
I have done a clean install of XP Pro followed by the D630 drivers but this is outstanding for a driver or some fix. The only USB item I have connected to the PC is a mouse and this is working O
I have had the following computer for a few days after purchasing from the Dell online store, Latitude E5540. The WiFi was having trouble connecting anywhere except close to my router, but recently the laptop is saying that a driver or hardware problem is detected in the Intel Dual Band Wireless-Ac 7260, and that Windows has stopped the device due to a problem (Code 43). The drivers are up to date, and connecting using an ethernet cable and checking for new updates tell me the drivers are up to date.
I just finished doing a clean install of Vista SP1 on my new Studio 1537. Everything has gone well, however when I checked Device Manager I have one device with an exclamation mark next to it. When I clicked on the unknown device properties it tells me that it is "Intel(R) ICH9M LPC Interface Controller - 2919" I've looked all over Dell's Driver and Download site and I can't find the driver for this device nor do I know what category I should look under. When I contacted Dell's support they wanted me to unistall the device and overwrite my current BIOS version, A07, with an older version, A05. I decided that wasn't the best way so I thought I'd ask here hoping someone could help. After my install I loaded the drivers in the following order per Dell's directions: Notebook System Software, Chipset, Audio, Video, NIC Card, Dell Quickset, Wireless NIC, Touchpad. I didn't download and install the SATA drivers from Dell's website because my drive model isn't one of the ones listed for use with the driver. My drive is listed as a ST9320320AS. I'd appreciate any help someone can offer.
I've got a XPS 15 (L511Z) which recently stopped charging the battery. It says plugged in but not charging when I hover the mouse over the battery icon. Luckily I've got an extended warranty and on contacting Dell they sent out a new charger. I plugged that in and the same result. In fact now when I boot the laptop it gives me an "The AC adapter plugged in cannot be determined" message.
Dell then asked me to buy a new battery since batteries are not covered in the warranty. Did that but still no luck. Am thinking that the original battery was ok to begin with anyway! Dell then asked me to update the BIOS but when I tried to with the update they gave me it failed, saying incompatible with the current hardware.
I then ran the DELL Support Center utility which identified another BIOS update which updated successfully but then I noticed that it changed the Product to L501X now. The charging issue still persists though.I've sent a response back to Dell but based on what I've been reading on the forums it looks like the motherboard would have to be replaced.
I installed a new hard drive on my Niece's laptop Inspiron 14Z (N441Z) and did a clean install of Win 7 Home Premium. I installed the Chipset drivers first and then started on the list displayed in the support area for this machine. After completing all of the drivers install, my device manager looked like this:
The Unknown Device shows an ID USBUnknown. This machine has 1-USB2 and 2-USB3 ports. If I run the Dell Diagnostics it shows that I have 1-1.1 USB ports, and 2-USB2 ports. The 1.1 port appears to works since it will recognize flash drives etc. This is also true of the of USB2 ports. The other USB2 does not recognize anything except my Samsung Galaxy 4 phone. But when it is unplugged I get a balloon on the task bar that says a USB device is not recognized. This will also occur when I first boot up the machine. It is like the machine is not recognizing the USB ports If I run any of the hardware troubleshooters that Microsoft has it tells me that a driver is missing but when it tries and install, it reports that it fails. I have undated my bios, all drivers, I have uninstalled drivers and then rebooted with no luck.
after i did clean install my os, i got a driver call unknown device..i install all the driver even gpu and intel chip.. it still having this problem. i use the online dirver updated but nothing found... then i use Hp.com online chat and ask them the problem but they couldn't give me an answer. now i am hopping you guy will know...
After installing Wind8.1 my Hp 250 G2 (FOY89EA#ABE) lost the PCI device and when I connect to HDMI or VGA, no picture is produced on the TV. How can I solve this problem?
just recently installed win7 x86 and everything seems to be working. I have one remaining unknown device under USB controllers and i am trying to figure out what it belongs to. my webcam works (although i think its listed as usb input device), and parser device, i/o device and texas mem stick have all been installed. i have also noticed that my fingerprint reader says that it is not connected when im first booting into windows although it works properly. could this unknown device have something to do with the reader?
I purchased yesterday the HP 450 i3-4000M and after installing alla the necessary it seems that one device is not activated but is staed as "unknown device".
After trying to find ou the identity of this device i found out the code name : ACPI/HPQ6007
I am trying to find the drivers for this device but it seems they are nowhere to be found..
Since a few days now I get the message'The USB-device was not recognized: One of the USB-devices connected to this computer does not work correclty. The device has not been recognized'. It keeps popping up from my right corner below, every 5 seconds if I don't click it. When I click the message, I get a list of USB devices (ports) there are available. There's one 'Unknown device'. Maybe it has something to do with the finger scan (biometric)? This hasn't been working very good lately..Even when there's no single USB device installed (normally I have a mouse and a Targus laptop chill mat installed as USB devices), it keeps popping up. I tried deleting the USB port from the list (or uninstall it) in Device control, but it seems it keeps happening.
I suddenly got it, I did nothing specific of did not connect any strange devices (except for a projector on the external monitor exit, but that has nothing to do with USB). I also hear the sound for connecting and disconnecting USB devics randomly when I'm on my laptop.
