ProBook 4720s - Showing "Unknown Device" in Device Manager

I have recently reinstalled windows 7 pro 64 bit on my probook 4720s. The device manager is showing a "unkown device" since then, the location path of the device is  "PCIROOT(0)#PCI(1A00)#USBROOT(0)#USB(1)#USB(3)" and the name of the physical device is "\Device\USBPDO-6 ".
I have tried finding out wich device this without succes, so my question is if anyone happens to know wich device this is.
Thanks in advance!

Hi,
1. Go to: Control Panel -> Devices Manager
Click with right button of Your mouse on each yellow sign with exclamation mark ( ) and choose properties. Then go to ' Details ' tab and paste here Hardware Ids . This way we will know what it is.
Below You've got example how to do it:

    What you need is the ACPI ( advanced configuration protocol interface) driver for the installed CPU. You can get that at the processor manufacturers support website. Intel's download center is here.

  • 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.

    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

  • 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.

    hi ktmcmo,
    Are all the USB 2.0/3.0 ports in the front/back part working fine?
    Some other steps that you can try:
    1. Download and run Nirsoft's USBDeview v2.27 (download here)
    2. Create a System Restore point
    3. On the USBDeview interface, right click on the USB controller/hub that's giving you the General Failure error and try to disconnect/uninstall or disable the device and observe if you still get the same error on USBView/Lenovo Solutions Center.
    - Link to picture
     4. If same issue occurs, undo the changes that you have made in Step 3 and make a create a registry backup. On the USBdeview interface, right click again on the USB controller/hub that's giving you the General Failure and choose Open in RegEdit. In the registry, delete the registry key and/or subkey of the failing device and reboot (Windows will automatically re-install the device using the inbox driver).
    - Link to picture
    Note:
    Only do Step 4 if you have a backup copy of your files and have created a system restore point / registry backup.

  • ITunes won't recognize my iPod. I have the Apple Mobile Device USB driver installed in my programs but it doesn't show up in my Device Manager or Services. Can someone help?

    So I connected my iPod to iTunes and an error message came up saying it needed an updated version of iTunes 64 bit and I was missing the Apple Mobile Device USB driver so I downloaded it because another discussion said that was the solution. I did but it wont show up in my device manager or services. Can someone help me figure out whats wrong?

    See

    - I would start with
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
    or              
    Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
    However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
    - Then do the other actions of:

  • No Audio Device Detected (but it shows up correctly in device-manag

    Well, I bought a new soundcard, since I was tired of my old integrated one, and wanted good surround-sound. The model is Creative Sound Blaster X-Fi Xtreme Gamer Fatalty, and my old integrated one is a Realtek-HD (doesn't say more than that).
    Now to my problem, I removed the drivers from Realtek (even cleaned lots of it from the registry) and put in the new soundcard in a PCI-slot, as it's supposed to be done. I then started the computer, canceled the automatic installation and installed the drivers from the CD I got with the card (this is what it said I should do), now the card shows up in the device-manager as "Creative SB X-Fi" and it tells me it's working fine etc. The Creative-update software also detects it so that I can download the latest drivers.
    However, I have no sound, and in the control-panel's "sound & sound devices" it says "No sound device" and I can't do anything. :/ (not sure if this is what it's called in english, I'm using the swedish version of Windows XP Professional), I can select the soundcard in creatives Volume Panel (where it says "select audio device") without any error-messages, but when I double click the application (to change the volume etc.) it says it can't find any supported soundcards.
    I tried removing the drivers etc. for the SB-card and installed the Realtek ones again, but it's the same thing there, it shows up in the device manager (under sound - video & gaming-units) but windows still says it can't find an audio-device. My guess is that there's some kind of conflict between the Realtek-integrated card and the new one.
    Anyone got any ideas of what to do? :/
    Edit: Also, the computer keeps wanting to install the integrated soundcard, but I can't seem to find any way to turn it off in the BIOS :/ (I have an ABIT motherboard, don't know what type, can't seem to find the box for it). The BIOS is called "Phoenix - AwardBIOS v6.00PG"
    I have ofcourse tried to fully remove and reinstall the SB-drivers aswell, but no luck there. :/

    next time go into control panel click on sounds, click on record, right click any where in the record box and then put check marks in the boxes that say show disabled devices, and show disconnected devices. Those devices disappear when the boxes are not checked making your pc think there is no output sound.

  • Amazon Q&A: E1200 - Shows unknown devices connected

    E1200 shows unknown devices connected I recently bought my first router. My question is that it shows multiple devices attached. When I chect the DCHP table it shows only my pc. Is there something I don't understand?

    Where do you get the info telling you that you have unknown devices connected to your router's network? Make sure to enable the wireless security of the router. Use WPA2 encryption. With wireless security enabled, it will ensure that no one else can connect not unless you provide them the wireless security code.

  • 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.

    (oh and i also didn't install modem drivers since i don't need the modem anyway)

    What OS have you installed?
    Windows XP?
    If yes, check if your Windows XP is up to date (install MS patches and hotfixes)
    Also install all available drivers from the Toshiba driver page like:
    Chip Set Utility, Storage Manager, etc and if there is an newer BIOS version, then update it.

  • Windows 8.1 laptop computer not showing in SCCM 2012 devices collection

    Hi,
    I am trying to do a POC on license management from  SCCM 2012. I have configures a SCCM 2012 server and intune subscription also. I have Android, iOS and desktop apps uploaded (.msi). when I enrolled android and ios devices its shows up in SCCM,
    devices collection but do not show in Intune.
    my company portal is nicely coming up on android and iOS tabs. on the other hand company portal showing only Web apps, on a win8.1/7 laptop.
    When I tried to enroll 2 windows 8.1/ 7 laptop (intel x86), they donot show up in SCCM. clients of intune manually installed, endpoint protection of SCCM installed also on both boxes.
    I tried updating membership in SCCM for both know and unknown type, many time and also triggered Deployment of some desktop app, to the win 8.1 laptops. the desktops are showing in Intune All devices -> all computers nicely. But
    not in SCCM2012.
    what did I missed, I tried to add all the logical roles. below is some details what shows up in Intune:
    indranil

    If you installed the Intune agents on the Win 8.1 and Win 7 systems, then they will never show up in ConfigMgr.
    There are basically two parts of Intune -- a Mobile Device Management piece and a Windows management piece. The Intune connector in ConfigMgr takes over the MDM piece and nothing more. When ConfigMgr takes over this MDM piece, as Torsten said, all MDM devices
    enrolled show up in ConfigMgr and not Intune because that's now controlled by ConfigMgr. The Windows management piece remains unchanged and separate though and so those systems will be directly managed by Intune only or ConfigMgr only.
    So you have three options there:
    - Install the ConfigMgr agent and managed using COnfigMgr
    - Install the Intune agent and manage using Intune
    - Enroll the systems using OMA-DM which manages them as if they were devices. This means so you don't get SCEP or Windows Updates or most of the other ConfigMgr functionality. This is only valid for Win 8.1 though.
