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've bought a B590 and installed a Win 7 64bit. I have installed all available drivers from the support page and have the following issue:
Device Manager:
I see 2 graphics devices
Intel HD Graphics
NVIDIA GeForce GT 720M
The discrete card is disabled with error code 43 and has an exclamation mark near it [URL] .... Moreover, if i start the NVidia Control Panel it gives me an error with text: "current display is not connected to nvidia GP" GeFoerce Experience is not starting with a back-end error [URL] ...
Now here are the ways i tried to use but it did not work:
1. Enable high performance and update with manually downloaded nvidia driver
2. Do the same with HDMI cble connected to a plasma
3. Disable enable the device (screen goes black, than to normal and everything stays the same)
4. Format c: reinstall Win8.1 64 and install all drivers - same thing
5. Format c: reinstall Win7 64 and install the graphics drivers after everything else (h1d9d9.exe h2d903.exe)
6. Update GT720M drivers from device manager (driver is up to date)
7. Run a high-performance 3D game (War Thunder) - it uses Intel HD
What else can i do? I saw people with switchable graphics use some kind of application to specify the game-apps that should use a discrete videocard. I don't have such an app to specify my games.

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.
Info from Solution Centre: Product: 3354AF7

Faced with the problem. No sound after the laptop. When you try to check the sound device, a window pops up "the device is already in use by another application." But no program is not running. After rebooting the laptop sound occurs. Drivers are all set.
Audio device Realtek ALC269
Win 7 Pro SP1 (x64) with all updates
Motherboard 20208
Chipset Intel Panther Point HM77
BIOS Version H5ET84WW(1.22) (11/26/2013)
UEFI boot mode, not Legacy.Drivers for sound downloaded from realtek.com.tw. With standard windows drivers sound is always there. Tried the previous version of the drivers - ineffectually. Could it be that the problem is due to the UEFI boot mode? I do not want to reinstall the OS mode Legacy just to check it out.

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 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 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.

BIOS: G5ET95WW (2.55 )
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"

Today I found an error in device manager "unknown usb device descriptor request failed" with error code 43. Then I found out webcam doesn't work/disappear. So I try to fix the problem and reset bios setting seem to get it back.
But in windows when I try to use webcam, at first it seem to work normally but after a few minutes it disappear and reappear immediately. Repeating this a few time it was again disappeared with the same "unknown usb device descriptor request failed" error.
Repeating the same bios thing again and it's back, running normally. Then I leave webcam program on(cyberlink youcam) to observe. It working fine for around ten minutes then it was repeating disappear and reappear again and this time it blinking like in this video [URL] .... so I turn off webcam, leave it for minutes and running youcam again and it's back to normal(Still working normally when I post this (working for around 25 minute now)).
What cause this. Does this mean my webcam is failing?
Also my webcam LED indicator flickering rapidly like the light bulb when turn webcam on and stop flickering when I point the bright light to the webcam. Is this normal?
Right after I post this it disappear and reappear again but only one time not repeating.
Now "unknown usb device descriptor request failed" is back and webcam disappear again.

I have a Lenovo IdeaPad Y560 which had both Intel and AMD drivers installed correctly, switchable graphics was also functioning properly.
The problem started when I tried to update the 2010 AMD driver with the latest one (2011) on the officail Lenovo site. The install seemed to run through, but informed me that there were warnings during the installation. I opened the linked log file, but it did not include any errors or warnings, only that the installation ran through successfully.
As the driver version still showed that it was the 2010 driver which is installed, I uninstalled the driver, and tried to install the 2011 driver again after a reboot. It once again said that the installation was successfull, but with warnings (still no warning in the log file). When I tried to check the driver version, it turned out that the AMD graphics card is not visible in the device manager, not even as an unrecognised device.
I then tried to install the old 2010 driver (the original driver installation files were already on my D: drive upon delivery), but got the same results as with the 2011 driver.
Removing any AMD/ATi related programs did not work either, I still get a "finished" installation with warnings, and a log file without warnings or errors.
OS is Windows 7 (64bit)
GPU: ATI Mobility Radeon HD 5730 (+Intel HD...)
Switchable graphics is turned on in BIOS.
how I could get the system to recognise the attached ATi graphics card, or at least realize that it is there?

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
&SUBSYS_3603103CPCIVEN_197B&DEV_2382&CC_088000PCIVEN_197B&DEV_2382&CC_0880

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've just bought a lenovo ideapad flex14.
Excellent little laptop, but i´m wondering about a thing.
Under device manager --> display adapters, theres is two graphicscard. But there should only be one in the machine?
The two graphicscard in question is:
- AMD Radeon HD 8330
- AMD Radeon HD 8570M
My model is:
AMD A4-5000 quadcore 1,5 ghz.
AMD Radeon HD 8570M
8 GB DDR3 ram
it should only be the AMD radeon 8570M with 1 gb dedicated memory.Furthermore severeal hardware info programs shows the same two graphics card, but only 8330 has temperature info, along with other informations.

I'm using Windows 8.1 on a t431s. I'm having this problem where none of my external storage is being recognized. Under "Device Manager" any sort of external storage I plug in ends up under "Other devices". When I click on the device, I get Code 28 "The drivers for this device are not installed." Trying to update the driver brings me nowhere. The devices don't appear under disk management.
What's weird is that other USB peripherals such as mice and USB headphones don't have any problem.
Here's what I've tried so far:
Updated the BIOS.
Used Lenovo's SCCM package for Windows 8.1
Tried installing the individual drivers for each hard drive.
Nothing works!

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.
