    Good-day to you all, I'm here with a necessity.
    The necessity to find out the solution to a problem that let me dismayed.

    I'm using Win XP SP 2, and short time ago, I've bought a memory card reader, those little usb.

    The problem it is that, when I use it on my computer I can't copy any files, nor from the card to any folder of my hard disk, nor from any file from the hard disk to the card.
    Seldom it works, and I can pass one file, but very seldom. If I want to transfer all the content of the card for example (1 gb) I can't. And when I want to see files that are in the card, it takes a long of time, just to visualize a single file, and when I want to copy it, I just can't or it takes a huge time.

    I tried this device in other computers running WIN XP SP 2, and it worked out.
    I have no doubts at all the that the problem is in my pc, and for sure in Win XP.
    It is not unrelated to say that other USB devices, such as Mp4, or Mp3 players, etc. etc. etc. (of high speed file transferring USb 2) work well.

    Not long time ago I tried installing my WIN XP SP 2, in another partition, just for trying if my WIN installation was bad or somethjng, but it doesn't work in the other WIN installation either.

    I checked out the CMOS and it is all as it should be. (I mean the USB configuration) it is marked "Enabled" in all the options.

    I tried connecting it in all other ports (from the front and back) but it didn't work either.

    The exact error is this

    "The request could not be performed because of an I/O device error."

    I just know that I don't know anything.

    What should I do to fix things out?

    I thank you very much for your suggestions and answers.

    Does the problem just occur on very large files?

    If you open the Device Manager (run devmgmt.msc) and look under the USB tree -- is there an entry there for an "Enhanced" USB controller? If so, is it "working properly"?

    You might try doing what is known as a USB "cleanup":


    First set a System Restore point and test it: start > run: msconfig > Launch System Restore.

    The standard approach to these problems is to remove all the USB devices in the Device Manager and let Windows reinstall them. But there is a special technique to it.

    I am uploading a registry patch you will need to download, unzip and run. Confirm the merge to the registry.

    It is the patch described in JohnWill's note here:


    Once you have installed the patch, follow the rest of his instructions.

    Note: in some cases Windows does not have the proper install path for the information files required. If the New Hardware Wizard prompts you for an install location, point it to:


    This is a hidden directory, so you will need to have "show Hidden Files" enabled in Folder Options > View to see it.

    Thank you very much for your help.
    The problem ocurrs with both, large and small files, even sometimes creating folders.
    But I found that, the first times it doesn't work properly, but if you keep trying, some times it works, that's the weird.
    I checked if there was an enhanced usb controller, and there is, and it is working properly.
    The idea is to make it work correctly always, not just some times with goodluck.
    I tried the process you told me, as you described it. But I'm so sad, it just didn't work.
    It was like always, the only thing was that I had to load the drivers (they auto-loaded) for using the card reader, but it stills working bad.
    Thank you for helping, I hope you know what's the solution to this.(y)

    >> Hmm, what is brand/model name of the card reader?

    I only have one so-called 9 in 1reader and it does not require any driver installed.

    >> when you plug it in, do you get a "detection" sound, and does the "safely remove hardware" icon appear in the System Tray?

    If you open the Device Manager and look under "Disk Drives" (check show hidden devices first), do you see something like what I have here in the attachment?

    Try removing all the "CARD" devices you see there and any "faded" or "ghost" entries and reboot.

    You may need to experiment with the "optimize" choice in policies, but if you do you should always use the "safely remove hardware" wizard before unplugging the device. If you haven't been doing this it may be damaged.
