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.

Non CISCO unknown devices are being discovered in LMS

Hi!
I have had no problem with discovery which was used on cdp basis so far.
Now the CDP packets do not arrive via new MPLS backbone network. I have to use the "ping sweep feature in IP range" feature. I had to enter more than 400 subnet from file before there are more than 400 branches. ( etc. 10.31-9.1-50.252 255.255.255.252 )
I have experienced two problems
1. The discovery never end ( now this is not important ) :-)
2. The common services -- device management shows discovered unknown devices whose ip addresses out side the range what are entered by me in the ping sweep range and theirs OID is not CISCO.
( 1.3.6.1.4.1.2001.1.1.1.1 , 1.3.6.1.4.1.11.2.3.9.1 , 1.3.6.1.4.1.674.10892.2 , 1.3.6.1.4.1.18334.1.1.1.2.1.7.1.2 and even more )
Due to more than 300 unknown devices the LMS device number is beyond the license number!!!!!
Our questions.
Why does lms add the unknown devices ( non cisco devices ) to the inventory ?
How could lms discover these devices ??? ) ( theirs IP are out of ping sweep range and non cdp capable devices )
Thanks in advance!

Thank you!
The unknown devices were in unreachable state and they were added to DCR.
I don't use include or exclude filter what were referred by bug.
In spite of i use seed device list from file the LMS ping sweep debug log shows that LMS try to ping other IP addresses!!!!
You're right, it is not normally operation may be TAC will be needed to solve it.
( whether who tested it ?)

Satellite 1700-300: No Lan port in the device manager

Hi Forum.
I am currently repairing a Sat 1700-300 and reinstalling windows ME (Yuk i know but it is the customers preference), however it doesn't show that there is any ethernet hardware on the system. There is an ethernet port on the back of the laptop but it just doesn't show up in the device manager.
My first though was that it may be disabled in Bios, which i have checked and there is no option there for ethernet.
Any idea's folks?

Thats a good question, however the work was only carried out on the hard drive and not the motherboard itself. The owner of the laptop has said that he has never been able to use the RJ45. My theory is that it was included on the board but never activated, hense the reason there is no metion of it in the specs or in the bios.
Is this very probable? and would a bios flash possibly resolve this issue?
Just to re-iterate, there is no entry in the hardware manager for the port or any unknown drivers at all.
The reason I posted on this forum is because it is a Toshiba forum, are there any Toshiba techies here or is this just a community 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.

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

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.

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.

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 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
Solved!

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.
