Problems Using a SanDisk Extreme USB 2.0 Compact Flash Reader with Windows 7 (64-bit)

    Question

  • I recently plugged in my SanDisk Extreme USB 2.0 Compact Flash Reader into a USB port on my new laptop PC running Windows 7 (64-bit).   In the device manager, it sees the SanDisk reader as a temporary, removeable drive (it even names it correctly as a SanDisk Extreme USB 2.0 Reader).   However, Windows 7 reports that this device does not work as the OS cannot find and load any device driver for it.   It asks me to search for a device driver.   However, when I do, Windows 7 finds nothing.   There are no special 64-bit device drivers listed on the SanDisk web site.   Their [SanDisk] technical support people tell me that Windows 7 should automatically load the USB driver for this device.   They don't have any special device drivers for this device.   Finally, as a point of reference, this reader did work seemlessly with my old laptop running Windows XP Professional.   It was a mear plug-in-play operation.   However, with Windows 7, this device is dead in the water.   Does anyone have a solution?

  • Hi, thank you for posting here.

     

    Dose this hardware compatible with Windows 7? You can check it on Windows 7 Compatibility Center

    Try to update your BIOS, delete all USB Root Hub in Device Manager and scan for  hardware changes to see if the same issue occurs.

     

    As it works well in Windows XP, you can try to use it in Windows XP Mode:

     

    Install and use Windows XP Mode in Windows 7

     

    Hope it helps.

  • There is no device driver necessary, except the GENERIC MICROSOFT MASS STORAGE DRIVER. IF windows identifies the device in the device manager correctly, there may not be a real problem...Do you use the safely remove hardware tab in the taskbar to load/unload your usb devices ? If not, windows can become "confused" about which kinds of hardware is installed at any given point in time. Is the device listed in the "my computer" section?

       Finally, in the device manager, you can right click the usb device, select properties, and then use the driver tab to try to install a driver if windows still cannot access the drive. INSTEAD of letting windows search for the driver, pick the "let me choose " option, then the "show me a list of drivers to choose from."  IF WINDOWS PRESENTS YOU WITH A LISTING OF DRIVERS:

    What you need is a generic mass storage device driver...look under the headings, and if you don't see this listed, uncheck the box that says "show compatible hardware." After several seconds, windows should return a listing of usb device drivers.  Scroll down them, to the "GENERIC" header, and there you should find the usb mass storage driver. If it's not there, there is another one, the same driver, in fact, under the MICROSOFT header, the generic usb mass storage driver. please note that after it is installed, you may need to restart the computer to write the new value permanently into the registry for that device.

        IF WINDOWS DOES NOT PRESENT YOU WITH ANYTHING TO CHOOSE FROM, OR SAYS DRIVERS NOT FOUND, THAT IS BECAUSE FOR SOME ODD REASON THE BETA TESTERS DID NOT FIND THAT THE DEFAULTS FOR THE SEARCH LOCATIONS ARE EITHER THE A: DRIVE (FLOPPY ) OR THE DOCUMENTS OF THE CURRENT USER...NEITHER OF WHICH WILL HAVE DRIVERS, OF COURSE.

    IN THIS CASE YOU WILL HAVE TO EITHER "browse my computer for drivers" or use the "have disk" option-(see how it's defaulted to the a:\ drive ?)and locate your driver files by browsing to the \windows\drivers folder or the \windows\inf folder, whichever one it takes depends upon whether your windows is a final retail version or an upgrade.

  • I tried your suggestions, but this is what I observed:

    1. I went into Device Manager and I chose the option "show me a list of drivers to choose from."   However, none of the choices was for an external USB drive.   I tried clicking on several similar devices, but none worked.   Windows still reported not finding a device driver.
    2. Never saw the option to "show compatible hardware."
    3. Windows does not present me with and driver choices.
    4. I tried searching for drivers under C:\windows\drivers folders as well as the C:\windows\inf folder but found no files that windows reported as containing a driver for the SanDisk device.

  • I tried several fixes along these lines on Win 7 (32), & nothing worked. Then instead of restarting, I shutdown, & turned the PC back on. I don't know why it worked, but it did.

  • I tried searching through the Windows 7 hardware compatibility list as you suggested but did not find the SanDisk Extreme USB 2.0 Compact Flash Reader listed.   Not sure if that means that it has not been tested or not.
