Card reader memory O2Micro on Latitude with Windows 8.1

I have a Latitude E5520 and a Lattitude E5530, have both the O2Micro SD memory card reader.  The drive worked fine in Windows 8, but after I installed the 8.1 update, the SD card reader works not at all when you insert a memory card.  There is no beep, no hard drive available in Windows Explorer, and in the device, the O2 Manager is not listed in "Storage controllers", where it should be.

There are two versions of the driver that I found online on the Dell site, but neither one solves the problem.

I've found this workaround, but it's not a very good:

  • 8.1 Windows, press the Start button and type peripheral difficultyand click on find and fix problems with the devices in the list of results.
  • Click Next and let it check for problems.  He will come with the option to activate the device Intel 6 series/C200 Series Chipset Family PCI Express Root Port 6 - 1C1A or something similar
  • Click apply this hotfix
  • Once completed, close the troubleshooter and open up Windows Explorer and you should see the card reader
  • In Device Manager, you should see Controller O2Micro Integrated MMC/SD controller O2Micro integrated MS/MSPRO

Now here's the bad news – once you reboot, or even go to sleep and come back, the card reader has disappeared, and you must repeat these steps.

If anyone has a permanent solution, I would like to know what it is!

I had the same problem with my guitarfish E5430 and thank you for your thing!

But I finally found the right driver and now everything seems to work fine, here's what I did:

-Go to the Dell driver site

-Tick: All drivers for your product

-Choose: MS Windows 8.1 64-bit

-Come on in: storage controller

-Installation: O2Micro Smartcard (driver O2Micro OZ77CR6 smart card)

  • Amazon Cloud Player or Google Reader works on the Surface with Windows RT?

    Amazon Cloud Player or Google Reader works on the Surface with Windows RT?

    I think that the answer is no, and if yes, what are the types of applications/services that are likely to be developed for the Surface (Windows RT) Finally?
    In addition, these things (Amazon Cloud Player and Google Drive) will be available on the version of Windows 8 fantasy of the Surface when it comes out?
    A Surface of Windows, I bought for my mother and I did not open and I just check all these things. A laptop is perhaps better for her, but I have little that this is best for some reason any.
    Thank you.
     
    Original title: amazon cloud player

    The Surface Pro is a full PC and runs Windows 8, you can install the Amazon downloader and download the song files as you do now on a regular PC. Surface RT runs Windows RT and does not run as many different applications such as Surface Pro.

    You can play songs streamed from the web version of Amazon Cloud Player on Windows 8 and Windows RT. Currently, I'm not aware of any way to download songs from Amazon directly on Windows RT. You will first need to download them on a normal PC and then copy them to the Surface RT if you want to listen to the songs without a network connection.

    There is no Google Drive for Windows RT application so far, but Microsoft did something similar, called SkyDrive.

    In addition, just for the record it is a Kindle for Windows 8 and Windows RT application, so that you can read your Kindle eBooks.

    I speak from experience, having recently purchased a Surface RT to play with. I hope this helps.

  • Internal card reader & USB ports stop working in Windows 7 64 bit - HELP

    This seems to be VERY popular problem between Vista and 7 users. I can't find the right difficulty any where. I have a HP Pavilion of D5200T running Win 7 Home Premium 64-bit. (I can provide more specific if necessary specifications). I read a few other posts in this forum with exactly the same problem as me, I tried the suggested fixes - most of them anyway - and my problem persists.

    This is the story of the kind: bought PC Cognac nine in June 09. It came with Vista Home premium 64-bit. On the front panel, I have the HP 15 in 1 reader cards and below that another panel with micro/headphones, 2 USB ports and 1 port Firwire catches. They all worked great worked great, no problem at all. I bought Windows 7 and improved in October 09. These two USB ports and card reader have been in place since then. I turn on the computer or restart works and they. Slide into a car SD, CF, whatever it is. Little green light turns on, windows automatically opens on the screen indicating the contents of the card.

    The card reader is no longer everything first. It may be 15 minutes later, perhaps hours. I slip on a map and still get the little green light but nothing on the screen. As if no card has been inserted. 2 USB ports will do the same thing, just much less frequently. I step a USB item and I have an error message saying: is not recognized or not installed properly. If I restart - they are all back to work very well.

    So... this problem only started after the Windows 7 installed, then it is clear to me is where the problem lies. When card readers or USB is in their State of non-working, I'll go to Device Manager and see that they are always listed, and there is no indicator of errors.

    This is what I remember by train so far, without success. I uninstalled devices from the Device Manager, driver too. I tried unplugging them from the card, restart, reconnected, reinstall. I tried different plugs on the motherboard. I can't find the latest drivers. The courses are MS 21/06/06 6.1.7600.16385. I think I tried all utilities integrated in Win7 to try and diagnose, and none of them produced no results. I tried to disable the sleep function. I even reached out to HP support, and the best they have resulted so far is that the card reader is bad. They are sending me a new, but I do not think that this problem will be solved.

    As I said, I see this problem or similar to many, many forums but I have rarely seen a happy ending where it was fixed. Someone at - it the key? Help, please.

  • TECRA M9 card reader still does not not with Vista SP1

    Why Toshiba didn't supply of integrated drivers for the card reader M series for people who do not want to run the Toshiba version recompiled Vista, which allocate Inc. of the unwanted software like Norton to slow down the Vista system!

    Im running a clean install retail Vista x 86 with updates, but 1-2-4 & 8gig sd cards will not work!
    in Device Manager it says "the device cannot start code 10".

    IM also beta SP1 which will detect the SD card, however cannot you read/write on the SD card.
    An update of the factory of the SD card reader Vista is whats needed!

    Hello, Robert

    At first, I must say that you are completely mistaken.

    The first Toshiba does not force someone to use the recovery image only. You can install your own version of Vista at any time. I also installed Vista Ultimate on my laptop. I also installed the just necessary drivers, download page of tools and utilities following the Instructions of facilities of Toshiba document. I hope just do you the same thing.

    As you wrote that you are on the tests of SP1. I also believe that Toshiba is also on the tests because SP1 is still beta version and so far not implemented the recovery image. Up until Toshiba offers no support for SP1. I can imagine different things will not work properly and Toshiba that will probably correct with the new drivers for the problematic hardware components.

    In the end, I can say: you can use your own OS installation like me and thousands of other owners of Toshiba laptop.

  • SD card reader not working only not with El Cap.

    The iMac does not recognize the SD card when inserted. Nothing in the Finder. If I leave the card in the slot and restart the iMac, it is recognized. This all started after the upgrade to El Capitan. Anyone?

    Hello leiffromtonsberg,

    Please ask for help in the communities of Support from Apple. Looks like you have problems reading from an SD card with your iMac. Here are the things I would check.

    The first thing that you want to make sure that the data on your Mac is safe. You will need to use Time Machine to backup to an external hard drive. The recommendation is to use an external hard drive twice the size of your hard drive internal. Use this article to help make a backup: use Time Machine to back up or restore your Mac.

    Then, you need to determine what you want to open or to display when you enter the SD card in. If you are looking for pictures to open when you insert the SD card, when you enter the SD card, open the Photos. On the import tab, there is a checkbox "Open pictures for this device". Make sure it is checked. If it is checked, uncheck it and re-check. It is necessary sometimes to get these settings reset.

    If you are looking for only to have a pop up on the desktop image, please go to the Finder, then click the word Finder in the next to the Apple menu bar. Click on Preferences. Make sure that you check the tab general, and that the box for the external drives. If it is checked, uncheck it and re-check. Close the Finder preferences.

    If you are still not able to find the SD card on the desktop or in the Photos, you will want to check if it shows up in disk utility. You can check by opening Finder > Applications > utilities > disk utility. Make sure the SD card is showing correctly in disk utility without having to restart the Mac.

    If you still have the problem, with the insertion of the card and read by the Mac, look for more updates. There may be a new update driver or firmware required to get this working correctly with the new operating system. Use the App Store, updates, or contact the manufacturer of the SD card to see if they can provide updated information.

    Thanks again and have a great rest of your day.

  • Satellite A100 PSAA9A - can read DVD BUT not CD with Windows XP

    I use a satellite A100 PSAA9A computer laptop and I started having trouble with the CD/DVD drive. It was working fine until yesterday when he decided not read no matter what CD I get the message asking me to insert a disc, when there is a CD in the drive. It still reads DVD good.
    I don't know if he has anything to do with the download of the updates of Windows XP because the troubl seems to start after I did.
    Is there somewhere in the creation for the player who controls this? Also when I run the troubleshooting test it always ignores the test of this drive.
    I'd appreciate any help.

    Optical drives, DVDS, has some different faces to work with CD and DVD, but objective and optics are the same. He had arrived, when in one two heads become a dust or something else. I thing that you must visit the Service and your disk cleanup. But do not use a cleaning disc!
    PS. Windows updates, as and OS, are not issues.
    Make sure it's easy - attempt to start bootCD (not BootDVD) with anyone by pressing F12 at startup. If the running machine - it's Windows, if not - DVD player.
