G500 - Unknown Device in Device Manager

Hello!
I just buyed a Lenovo IdeaPad g500 from here (so you can see the specs):
http://www.pcgarage.ro/notebook-laptop/lenovo/156-ideapad-g500-procesor-intel-pentium-2020m-24ghz-4g...
I installed windows 7 and then i installed all the drviers from the cd. I doublechecked, i did not missed anything. Then I updated some drivers to the new versions (chipset, video, audio).
But still i have a device with missing driver. It says Unknown device. under properties/details i found this:
Hardware Ids - root\LenovoVhid
Physical Device Object name - \Device\0000003a
I have succesfuly installed Energy Management and Thinkpad Management drivers too, but the device is still unknown and missing driver.
ThankYou very much!

Hi Morega,
Uninstall Lenovo Energy Management Power Management and try with this one: http://download.lenovo.com/consumer/mobiles/emw7034.exe If it does not help too, uninstall it and try with the one for Windows 8: http://download.lenovo.com/consumer/mobiles/e80femww.exe The first one I linked could help.

Hi Preko.
I assume device manager showing a driver missing, If so right click it then click properties then update driver tab.
You may want to visit lenovo`s website & update all drivers for your laptop.
Also make sure you have the latest version of Lenovo soloution center, The latest version number is 2.3.002.
Once you have done this re-run the hardware scan, Hopefully this will solve your problem.
And welcome to the forum.

Will it charge when connected to a wall outlet? The USB port on your computer must be 2.0

IPod appearing in Device Manager as unknown device

Hi, I'm currently using an iPod Nano 4th Gen. and it is appearing in Device Manager as an unknown device. I found this out after the error message "USB device not recognised" or something, and followed instructions. I'm currently clueless on what to do. My OS is Windows 8. When I go into properties of the unknown device (iPod) the device status is: Windows has stopped this device because it has reported problems. (Code 43). And in details, I get: USB\DEVICE_DESCRIPTOR_FAILURE
If you need any more information to help me, please do not hesitate to request it. I just really would like this issue to be solved. Thank you in advance.

Thank you for the update, passionflower
I think next would be a good idea to shutdown the computer, and disconnect everything from it. Let it sit for a minute or two, then plug it all back up and turn the computer on, then try again.
Next I would start troubleshooting the USB ports on the computer. I would start with this troubleshooting.
On the Start menu, click Control Panel.
Double-click the System icon.
Click the Hardware tab.
Click Device Manager.
Scroll down the list of devices to the Universal Serial Bus controllers
Click the plus icon next to the Universal Serial Bus controllers.
Double-click one of the indented USB Root Hub entries.
Click the Power Management tab.
Deselect the "Allow the computer to turn off this device to save power" option.
Click the OK button at the bottom of the window.
Restart the computer.
From: iPod not recognized when connected to Windows laptop over USB
http://support.apple.com/kb/TS1401
And then this troubleshooting
Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.
Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.
If you are using an accessory, remove the accessory and connect the device to the computer using only the Apple 30-pin to USB Cable or Lightning to USB Cable.
If you have access to additional Apple 30-pin to USB Cable or Lightning to USB Cables, try testing with another if the first one doesn't work.
Restart your computer and device. To restart your device:
Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.
Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.
From: iOS: Troubleshooting USB connection
http://support.apple.com/kb/TS1286
If you have another computer you can also test the iPod Nano there to help isolate whether the issue is with the iPod or the computer.
And just in case the issue is still not resolved, I want to thank you for using the Apple Support Community. Due to the nature of your issue you may find more information by using another one of Apple's support resources - https://expresslane.apple.com/GetproductgroupList.action.
All the very best,

IPAD 1 problems after ios 5.1.1 update, itunes does not recognize IPAD.. I check the device manager, it identifies an unknown device (My ipad) but unable to use it.

I am using the generation 1 IPAD.
I recently updated my ios from ios 4 to ios 5.1.1, I did the restore after the update and all seemed fine as it was detected the first time.
I tried connecting the IPAD again but it shows that the computer, itunes is not able to detect the IPAD.
I checked on the device manager, it identifies an unknown device (IPAD) and says no software for the driver. I am using windows 7 on my laptop. I never had any such problem with the iso 4. Any suggestions as to how this can be solved?
Thanks,
Vinay

Thank you, I tried uninstalling the device driver to reinstall again. After doing the scan for hardware changes, nothing flashes on the device manager. I dont see anything related to the IPAD or any other device for which driver shows unidentified device. It is as though the device is not being seen by the computer at all..
I even tried flashing the home/sleep buttons together but that doesnt seem to identify any device either.
Anything else I am missing?

Playbook showing as unknown device in desktop manager

Hi
Just bought a Playbook and wanted to transfer some files across to it. Unfortunately I have come up against a fairly major problem with this. First thing I did was connect it to my PC and start up Desktop Manager, unfortunately the Playbook comes up as 'Unknown Device'. Tried checking all settings including everuything recommended in article KB27464 with no success. The Playbook shows as network device in Device Manager in both the PC's I've tried (one runing Win7 Starter and the other Home Premium) and as far as I can see all settings correct but no joy.
I then tried using the network share option as suggested on the support site. Typed in the relevant IP address (file:/192.168.1.5) in the run dialogue after truning WiFi sharing on with no luck. All I get is Windows can't find the relevant folder! Then tried the same technique but using the USB IP address but still no luck!
Can anyone help me as after many years of enjoying various blackberry devices this tablet is wearing my patience very thin.
Carl
Solved!

Hi
Thanks for the reply, I was going to return the tablet this morning but thought I'd give it another go. Anyway after turning off both WiFi and Bluetooth as well as disabling sharing I plugged the Playbook in and it was detected! Anyway now managed to get it synched, updated and bridged to my 9900 so everything's looking great.
Thanks again for you advice, hopefully I can help someone else in the future as I get to know more about the tablet

HP Elitebook Folio 9480m drivers missing / Device Manager PCI Device and Unknown device?

Hello all, I have already installed Windows 8.1 Pro x64 and i have on the device manager still 2 missing drivers they are PCI Device and Unknown device??
Please see attached a printscreeen. ANy idea which drivers are missing? Thank you all

Hi: You need this driver for the PCI device... http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_134503_1&swEnvOid=4158 I gave you the driver for the unknown device when you had W7 on the machine, so it is probably the same one. http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_132986_1&swEnvOid=4158 If it is not that one (or you had two unknown devices at one time, and already installed the 3D driveguard driver), then it is probably this one... http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_133322_1&swEnvOid=4158

G500 dedicated AMD Radeon card missing in device manager

Greetings to all,
I've got Lenovo G500 laptop (i5, 6GB RAM, Intel HD4000 + ATI Radeon 8750HD, Win 8.1) and I am experiencing a serious problem. Yesterday my laptop suddenly freezed during watching a TV show and I was forced to restart it. After restart I received a message, that AMD Catalyst and hydravision doesn't work properly and I should reinstall drivers. So I did but after that, nothing worked properly and my radeon card was missing in device manager, just intel HD was present. I've read throughout this whole forum and I couldn't find a solution; I've tried everything, reinstallation of all drivers, both AMD and Intel, I've tried installation of older drivers, then newer, I've tried to check BIOS, where it all seemed all right (switchable graphics were enabled) and as last option I've reinstalled whole system - back to the factory settings. But my AMD Radeon card is still not present in the system, it seems like it was not ever there. I've tried to find it via that app which finds any hardware, but without any positive result. When I try to run catalyst center, it says "can't run catalyst, no actual settings which could be configured by catalyst control center". I've tried to play various games (far cry 3, mass effect 2, metro redux) with positive outcome, it runs the same way as it did before, but!! - I've got this feeling it always ran on intel hd card...As many others, since the beginning of my laptop purchase I had that problem where everything runs on integrated card instead on the dedicated, but I did not pay much attention to it, since it worked smoothly anyway. I'm not hardcore gamer, or a gamer at all anyway.....so to sum everything up, I think my radeon card is burned or damaged somehow and it didn't work since the very beginning. But still, I would love to get more professional opinion, because it is simply weird, it is missing in device manager. And one more thing, everytime I close the screen end reopen it later, system freezes or something doesn't work or some other inconvenience, leading to forced restart of the system. I thought it's caused by Win 8, because, honestly, that system sucks, but right now I think it's got something to do with that video card problem.
Thanks in advance and have a nice day ;-)

The NIC is defective... As far as Windows is concerned there is no NIC so the driver will not install.
Motherboard replacement is a bit extreme for just a broken NIC. Its possible to get a USB to Ethernet cable:

What is my 'Unknown device' in Device Manager? - ThinkPad T40 2374-75U

One more yellow ? to go. Thanks to the good advice rampant on this forum, I was able to figure out how to install the other drivers I needed.
This last one is messing with my mind tho. It's unfair for a problem to not even have a name, doncha think?
About all I can fathom about this 'Unknown device' is its location: 'on Microsoft ACPI-Compliant Embedded Controller'.
I tried the driver for 'Embedded Controller' and when I double click, it takes over the computer and tells me not to shut it down and begins installing 49 fixes. When I did it, the program got to the 21st fix, and that was as far as it would go. I shut down the computer after about 20 minutes. It did not remove the 'Unknown device' remark in Device Manager.
What's a poor boy to do?
Also, Windows is taking forever to load. This was not the case yesterday. Thanks for all your help.

SL 300 Unknown device in Device manager

Hello!
I have found in Device manager Unknown Device: ACPI\LEN0014.
SL 300, Windows 7 64bit.
Does anybody in this forum have any idea how to solve the issue? Or at least idea where should I look for further help...
The problem is that from the information available, I do not have the slightest idea what is the troubling device.
I have tried to install official Power management driver (found as advice to the similar issue)... But device is still there...
Thanks a lot!
Best regards,
Bojan

Hi,
The hardware id is for the Validity Sensor Driver which is on the following link.

Dv7-3165dx unknown device in device manager

I have a dv7-3165dx. I installed and intel SSD and windows 7 professional 64 bit.
I downloaded the device drivers from the hp web site, but still have 1 unknown device in device manager.
How can I figure out what I need a driver for?

Don't know if you ever got this resolved but the issue I think, assuming that you were having the same problem as mine, is the Webcam. Check the device manager see if an Imaging device appears. If not this SP should resolve the issue. It resolved mine. HP DV7-3165DX Windows 7 64x fresh install.

So... the last problem remained it's The Unknown Devices.

hi nikos78,
Can you check if this is the driver for it.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/gtku09ww.exe
Check if the Hardware ID of this device is a ACPI\VPC2004
on that same windows that you posted click the Details tab and change the value to Hardware ids
Now check the detail that will show below, if that shows ACPI\VPC20004 then that is a Lenovo Energy Management Controller.

Y530 "unknown device" in device manager, windows7

Hi
I am running Windows 7 on my y530 (geforce version), and everything basically works fine. The only thing that is really bothering me is that I have an "unknown device" show up in the device manager. I have installed all the drivers that are avaliable on the lenovo support webpage, but i the unknown device is still there. Anybody know how i can fix this issue?
Oh and those soft keys do not work for me, other than the play/pause/ff/rewind keys. I did install the hotkey drivers, but that didnt really help.
Would be great if somebody could help me out here.
Many thanks in advance

thanks bananaman for welcoming me and also for responding to my query.
well i checked under details and it said something about ACPI. After doing a quick search I figured out that it had something to do with the power management software. I downloaded the software from the download section on lenovo.com and voila, the unknown device was gone
The only thing that still doesnt work are the various sound option (jazz/rock etc...) and the dolby surround touch keys.
