Sony :: Windows 7 SZ4 32bit Unknown Device
Dec 18, 2009
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 have just successfully installed 64-bit Windows 7 Home Premium on my SR41M, along with some 64-bit sony drivers I managed to find...
However, in my device manager I am left with a single device unaccounted for, listed merely as "Base System Device". I have absolutely no idea what it is.
what driver I might need to install to resolve this..?

I am looking for a driver to suit an "unknown device" that is being reported by the Device Manager. The properties of the device are that the driver is not installed (Code 28) Details of the device are that it is located on PCI bus, the value is ACPIHPQ6007 and the resource type is IRQ setting 0x00000017(23).

I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.

I have HP ENVY 15-j15ea and 2 problems with it.
1. After reinstalling Windows 8.1 64 bit I can't find the driver for unknown PCI (bus 6), which hardware ID is:
device PCIVEN_10EC&DEV_5229&SUBSYS_198A103C&REV_01PCIVEN_10EC&DEV_5229
&SUBSYS_198A103CPCIVEN_10EC&DEV_5229&CC_FF0000PCIVEN_10EC&DEV_5229&CC_FF00
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?

Windows 8.1 - Installed from scratch.
I was able to install and configure all drivers but one. I found a tread that suggested installing Lenovo Setting Dependency Package 2.0.0.13 to fix it on a different lenovo model. I tried it without any success.
The driver id of unknown driver is "{48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver"

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 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.

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 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 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.
Base System Device (PCI bus 6, device 0, function 1):
PCIVEN_197B&DEV_2382&SUBSYS_3603103C&REV_00PCIVEN_197B&DEV_2382

I've installed Windows 7 32bit on my Vaio VGN-SZ330P. I got everything working fine, except the SmartWi Wireless Switcher:

Windows hangs up during shut down when SmartWi is installed. When I am removing it - everything works normal again.
Maybe someone has another Wireless Switching Utility for Vaio-SZ?

I bought a used Sony Vaio Laptop today.
I live in the Caribbean so its usually a little more expensive but over all I think it was a fair price.
But I really really love this laptop, the guy even put in a brand new western digital 320 GB HDD in it because this laptop was giving problems before so he decided to replace the HDD.
I am just concerned about the LCD lamp life and I hope this lappie lasts me another 3 years or more. I heard SONY quality in their laptop has depreciated.
Anyways the WEB CAM is not working because it needs drivers and when I use the short cut for screen brightness isn't working. I am not sure if its a fault with the laptop itself though. Because when I use shortcut for speaker mute with the fn key they work. All except the screen brightness.
I keep getting errors every time I try to install the windows vista drivers.
Also how do I recalibrate the battery for this? I think the battery is having issues charging and keeping a steady charge the estimation it gives is very out of alignment so to speak.

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.

I updated LENOVO V570 to win8.1, every thing looks good except the unknown device question mark in device manager.
It looks come from the power manager driver, because in the message center, it is said, power management does not work with a compatabale problem.

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 basically used my webcam every night with Skype to talk to my friends. The very next day, it stops working. Ive literally tried everything. In the device manager, I have an "Unknown Device" listed as a USB. Im 100% sure this use to be my Camera.
I just used the Acer factory CDs to reinstall my OS + Drivers. All the drivers were successfully installed with the exception of the Camera Drivers (because the computer doesnt see a camera)
I tried to download the drivers from the Acer website but (both Chicony and Suyin) and everytime I try to install them a error comes up that says "Camera not found!" I have a laptop so I have no clue how its not finding it.
ive been working on this for hours now and its really getting frustrating. Here are the things ive tried, and if someone knows a solution or a different method I havent tried to fix it, PLEASE let me know
My methods:
1. Reformatted computer using Acer recovery discs
2. Downloaded and tried to install drivers from acer website (camera not found problem)
3. Put windows in Safe mode, uninstalled unknown device, restarted computer to let it automatically scan/update (still failed)
4. Deleted all pictures from My Pictures
5. Tried using Windows Vista drivers and setting to Vista Compatibility mode (I have windows 7), no avail
6. Uninstalled and reinstalled Unknown Device (aka camera) driver, didnt work
7. Tried the windows update software option, windows said everything was fine (pshhh).
8. Uninstalled unknown device, used the option "scan for hardware changes" still didnt work
9. Installed skype to see if the webcam would be recognized, which it wasnt.
