Win8.1 on a new E540 - Card Reader Does not work

Hallo,
I just got my new E540 (i5, 4GB, FreeDos) this weekend and installed Win8.1 64 Bit Pro. After some trouble with drivers, it seems thant everything works - except the Flash Card Reader. I tried to install the driver from the Lenovo Support Center and directly from Realtek - both installations work but not the card reader.
It seems thant Windows (?) cannot identify. Probably that is what the device manager means with "PCI Device" and "Unknwon Device" (sorry for the german screenshot).
Can somebody help me?
Kind regards
C.D.

Hi,
Welcome to Lenovo Community Forums!
I’m really sorry to hear that you had trouble finding PCI device drivers for your Lenovo Thinkpad E540.
First of all, you need to find the Hardware ID of the device for which you need the drivers.
 1. Right click on the device that you need to identify, then choose properties.
 2. Once you have the properties Windows Click on the details tab.
 3. On the details tab Choose Hardware ID on the Property Drop down box.
Eg: PCI\VEN_8086&DEV_10F5&SUBSYS_20EE17AA&REV_03
Spoiler (Highlight to read)
Go to PCI DATABASE and enter the DEV value into the device search. Find the matching VEN value from the results and that would be the exact driver you require for your system.
Hope this helps! Post back if you face any difficulties in installing the specified driver.
Best regards,
Mithun.

  • Media Card Reader does not work on W541 (is O2Micro, not the RealTek)

    Can not read an SD card on my W541.  It reads fine on a W530. Reviewed the ReadMe, and tried to find the driver in the WIndows "Device Manager" but no luck.Experimented and found that if I did the following:Brought up Device ManagerUnder "View" menu, chose "Devices by Type" (this should really be in the instructions, although perhaps not necessary).Under "Action" menu, chose "Scan for hardware changes"found that the node labelled "Storage Controller" finally appeared (towards the bottom, just above "Storage Volumes")  There was one entry under the node, that of "ByHubTech/O2Micr Integrated MMC/SD controller".  The icon preceding this entry had a yellow triangle, so at least the system detected something was wrong. Right clicked on the entry and chose "Properties" and resulting dialog had the following text in the "Device Status" area (on the "General" tab): This device cannot find enough free resources that it can use.
    (Code 12)
    If you want to use this device, you will need to disable one of the other devices on this system. I have no idea what "resources" are being referred to in the message (a case of "I've got a secret"?), so it is a little hard for me to understand what other devices I might want to free up. Bios is version 2.20The "BayHubTEch/O2Micro Integrated MMC/SD controller" driver version is 2.2.2.1057 (which is the latest as of 6/26/2015).Runnin Win 7 Enterprise + SP1, 32GB RAM.

    Hello,
    I don't have a W541 myself, but here are a few things to check, in no particular order:
    Have you checked with your IT department?  Maybe they set a poilicy to disable the card reader.
    Is the card reader correctly enabled in the UEFI firmware?
    Have you run ThinkVantage System Update and Microsoft Update to confirm all of the various Lenovo and Microsoft updates are installed?
    Do you still have the OS image the device originally shipped with?  If so, does the card reader work under that?

  • SanDisk USB 3.0 Card Reader does not work with OSX Mavericks.

    Since updating to OSX Mavericks (10.9) My  USB 3.0 SanDisk "ImageMate All-in-One" Card Reader has begun to fail.
    It all seems to work proper at first. The memory card shows up in finder and I'm able to browse the files. But when I try to transfer any files it un-mounts from finder and only transfers the first file.
    This does not happen under previous OSX versions. I have tried on other computers since, so the card reader is fine.
    My USB 2.0 card reader saved my life this time. It works totally fine.
    Is this a known problem? Are you guys working on it?

  • Satellite Pro A200: Card Reader does not work after XP installation

    Hi...
    I have removed Windows Vista from my Satellite Pro A200 in favour of XP Home.
    I'm much happier with the machine now but am unable to get any response from the Card Reader. There's no mention of it in the User's Manual that came with the machine.
    I can't find any reference to it in the Control Panel's Hardware Manager and nothing changes in there when I insert an SD memory card.
    I didn't have cause to try the reader prior to removing Vista, so I don't know if it ever worked... although I imagine that it did.
    Running a search for a driver in the download section didn't have any success and this forum has no direct answers.
    Does anyone have any idea what I need to do to get this to work?
    Popa Mintin.

    Hi
    I dont see any serious reasons why your card reader shouldnt run/function with installed Windows XP.
    What you need is the right driver.
    The Toshiba driver page provides all Win XP drivers and there is also an XP driver for the multi card reader.
    You need a Texas Instruments Flash Media Driver. This is a driver for your Bridge Media Slot.
    This slot lets you insert either a SD card, Memory Stick (Pro) or xD picture card.
    Cheers

  • Satellite C850-B635 and Win7 - card reader is not working

    My notebook came with windows 8 and the card reader was working
    but I installed windows 7 64-bit , downloaded all required drivers to my notebook , but the card reader is not working now .
    I downloaded a driver called card reader controller but it didn't work as well
    I don't know if there is a problem or there is a driver that I should install and I don't know .
    please help me solving that problem .
    In my windows device manager these devices isn't recognized :
    *PCI simple communications controller
    *SM Bus Controller
    *Unknown Device
    I tried to search in my drivers download page in Toshiba website but couldn't find these
    please help me making my card reader working again.
    Regards
    Message was edited by: domaking

    To me the case is simple and the reason why the SD card reader does not work is that an compatible driver isnt installed.
    My theory seems to be correct since the SM bus controller and PCI simple communications controller appear in the device manager and I guess one of these devices belongs to the SD card reader/controller.
    I think you should simply install this Realtek Card Reader Controller which I found on the Toshiba EU driver page
    http://support1.toshiba-tro.de/tedd-files2/0/carc-20130924161048.zip
    Furthermore you should install all other Win 7 drivers as well as Toshiba tools available for Satellite C850 series.
    Very important is the chipset driver, USB 3.0 driver (Win 7 needs this driver to control the USB 3.0 port), display driver. etc
    Not very essential tools are Bulletin Board, Online Product information, Reeltime, etc such additional tools dont improved the notebook performance so its up to you if you want to use these software parts

  • W520 Smart Card reader does not show up in Device Manager

    W520 Smart Card reader does not show up in Device Manager.
    It was working before and now nothing.  Nothing happens when SD card plugges in.
    Could my smart card reader stop working or is this a configuration issue?
    Any thoughts?
    thanks
    Ian

    Hi  Ian,
    Welcome to the community, and thanks for the post.
    The issue is related with software, to resolve this you need to re-install the card reader driver from the below mentioned web link.
    http://support.lenovo.com/en_SG/downloads/default.page?
    After that check if the issue get resolved.

  • Tun miniport adapters are not working and the camera card reader is not working on a T61P.

    The Microsoft tun miniport adapters #4,2, and 3 are not working.  They display code 10 error message. Also the USB  mass storage device (camera card reader) is not working. 
    I have tried to uninstall and update the drivers to no avail.  I have used ThinkVantage Tool Box.  It only lets me know that they are not working.  It does say to reinstall them.  I have tried.  All effort has failed.
    All was find until I ran several updates via ThinkVantage.
    All suggestions would be appreciated.
    Thank you,
    Tom

    You will not lose data if you back up

    Reset
    Restore  best as new since you have issues ,then you will know if it has started to function correctly ,if not .....
    Visit Apple store since if it isn't software probably iPhone is on it's way out

  • HELP!!! My Card reader is not working!

    My card reader is not working and this is extremely frustrating when trying to transfer data from one device to my my macbook pro.  Is there any one out there that can help me with this issue?

    Some people (me included) have found the problme to be a stuck contact inside the socket on the MacBook Pro.  The far left contact appears to get stuck in the "inserted" position (depressed) and fails to signal to the computer that a new card has been inserted.  This contact is partially hidded behind an alignment key molded into the socket.  One fix is to carefully (and I mean carefully) use a toothpick to gently prod the contact into its "not-inserted" position (it will pop up and work afterwards).  If you aren't comfortable doing this yourself, you can get an inexpensive card reader that connects via USB as a workaround.
    If the computer is still under warranty (or you have AppleCare), take it in and let Apple or an AASP fix it for you.

    Thanks for your suggestion. I downloaded OnyX and ran the cleaning function. After restarting, I opened Help and once again the first screen appeared fine. But again most of the links did not work, though those under the "What's New" heading did work. I might add that I had previously tried a variety of suggestions posted in another thread, which included deleting from the caches folder in Home>Library several files such as com.apple.helpui and help.plist in the Preferences folder. (As noted in my previous post this evening, I also created another user but that also did not have any effect.) Any other ideas? Thanks

    And what does any of that have to do with Adobe software? You better check your hardware setup and install the proper driver for whatever card reader you use...

  • In the absolutely new 5S the gyroscope does not work, error are stable three degrees, calibration is hindered

    in the absolutely new 5S the gyroscope does not work, error are stable three degrees, calibration is hindered

    Also, I probably should have added that I am with Vodafone, and I'm currently using the Blackberry Curve 3G (9300) on the version 5 software. I also have no access to the Internet, which is telling me I have no signal. I have full 3G signal, so there is no issue whatsoever with my signal. I don't use the BBM on the phone, so I'm not sure if the issue is affecting that also, but I assume it would.

  • TS3989 New MacAir but  photostream does not work.  Message though everything is on. "In order to use Photo Stream, you have to be signed into your iCloud account in System Preferences." And,

    New computer but Photostream does not work.  I am signed into my account but get the following message:  In order to use Photo Stream, you have to be signed into your iCloud account in System Preferences.  I go to system preferences and then get a message that says that my account cannot be accessed.  However, I am using my icloud account for email and other items and it works fine.  Any thoughts?

    Are you getting this messages in iPhoto? If so try the following (again?):
    Log out of iCloud in the System/iCloud preference pane and disable Photo Stream in iPhoto's Photo Share preference pane.  Then log back in and re-enable, respectively.  That should jump start Photo Stream.
