Instructions on how to remove USB in order to reinstall it.

Please note that you need to have your scanners USB cable unplugged either from the scanner itself or from the computer, it makes no difference.

  1. You need to reboot your computer into Safe Mode. To do this you need to Click on Windows 95 Start Button à Shut Down and the Shut Down Windows box will appear:

    Shut Down Windows

  2. The computer will begin to reboot and when you see: Starting Windows 95… press F8.

  3. You will see the menu Microsoft Windows 95 Startup Menu, you want Safe Mode, and this should be choice 3. Read your menu to make sure before just pressing any number.

    1. Safe mode is a feature of Windows that runs without loading unnecessary drivers.

    2. The first thing you will notice is that you are running in 640x480 with only 16 colors. In all four corners of the screen are the words Safe Mode, a nice reminder.

    3. You will given a prompt like this, just press Ok:

  4. Once in Safe Mode you need to open up you Control Panel.
    1. To open the Control Panel go to Windows 95 Start Buttonà Settings à Control Panel.
    2. Look for the icon called System. System

      System Properties - General Tab
    3. Open the System icon and click on the Device Manager Tab.

  5. Click on the Device Manager tab. You will see a list of all of the devices on your computer, scroll down to the bottom where you will find:

    1. Universal serial bus controller. Press the + that is next to it and you should see two other devices:

      1. Standard Universal PCI to USB Host Controller.

      2. USB Root Hub.

  6. You want to delete both of these.

    System Properties - Device Manager

  7. As you remove each device you will be asked to confirm your decision.

    Confirm Device RemovalConfirm Device Removal

  8. Once both have been deleted you will notice that the Universal serial bus controller has also been removed.

  9. Close the System Properties, Control Panel and all other programs that might be running. Shutdown your computer and reboot. Let the computer boot-up normally.

  10. When the computer restarts it will automatically look for the USB files and try to load them. The system should begin a Hardware Detection search, it will look for the proper drivers on the computer and if it can't find them you will be prompted for the Windows 95 Disk, most likely your CD-ROM.

    1. You can do one of two things at this point.

      1. Try and have Windows 95 install the USB files on its own, I recommend trying this first.

      2. Cancel the attempt and install the files that you have downloaded from my web site.

    2. If you try 10.a.i) this does not guarantee that USB will be running. All you are trying to do is see if Windows 95 is able to install it. Once this is done I would then copy the 4 files: Openhci.sys, Uhcd.sys, Usbd.sys and Usbhub.sys to the C:\Windows\System directory.

    3. I would then install the file 95b_usb.exe. This file will make your computer 950 b, if it is not already. You can still run this install even if Step 10.a.i installs.

  11. Once all of Step 10 has been completed, reboot the computer. The Hardware Search should begin again, but this time it should find the USB port(s). If Windows 95 is still asking for your CD-ROM then point it toward C:\windows\system. This computer should then finish installing the USB Controller and then install the Root hub.

  12. If all goes well to this point and the computer finishes and you are now at your desktop, go into Control Panel à System à Device Manager à and scroll down to see if you have the Universal serial bus controller, it should be there. Also click on the + to make sure you have both the Standard Universal PCI to USB Host Controller and the USB Root Hub. Please keep in mind that not all computers are created equal. I only know that these are the 2 devices that I see on my computer. Others have told me that they also see the same thing in their Device Manager. As the saying goes, "Your mileage may vary".

  13. At this point I am assuming, yes I know what it means to "Ass-U-Me", that you have already installed the scanner software as per the scanner directions. If you haven't then you need to follow the directions as spelled out in the scanner manual.

  14. If you have already installed the scanner software and USB was not working, this is the reason that you are reading this! Plug in the power cord and the USB cable to the scanner. At this point the computer will do one of two things.

    1. It will find the scanner and attempt to load the proper scanner driver. This is what we are shooting for, obviously! Goto Step 15.

    2. If nothing happens then Windows 95 does not see the USB ports. Goto Step 16.

  15. If your computer installs the scanner driver and everything seems fine, then proceed with the rest of your scanner manual and learn how to scan. I am glad I was able to help. J

  16. For some reason Windows 95 still does not see the USB port, or it does not see the scanner. We need to trouble shoot a little bit more.

  17. You need to work your way backward.

    1. First thing to check is make sure the USB cable is plugged into the scanner all of the way.

    2. Check the power cord, is it plugged into both the scanner and a power outlet?

    3. I found when installing my scanner that since I have 2 USB ports, when I first installed the scanner I had plugged the USB cable into port 2 I was not able to get the scanner to work. Once I changed it to port 1 the scanner was recognized. Check this… you never know.

    4. Check the Device Manager, make sure that you see the Universal serial bus controller.

    5. Try rebooting the computer again with the scanner plugged in one more time.

  18. If all of the above does not help, you can e-mail me and let me know what is going on, or you can contact the scanner manufacturer and or the manufacturer of your computer. I kept getting steered toward the purchase of Windows 98, this is why I started all of this!

  19. I will make every attempt to help you get your scanner up and running.  Please contact me, either via E-mail or through the Web Site
