USB device can't connect

I just purchased new USB scanner (Visioneer 7700) and all the installing process seemed to be fine. After that it was found that the scanner was not connected and the software seemed unable to find the scanner.

I checked the Device Manager and found:

 Universal Serial Bus Controllers
 --- Generic USB Hub
 --- Intel(r) 82801AA USB Universal Host Control
 -!- USB Device  <--- ****
 --- USB Root Hub
 --- Visioneer PhotoPort 7700 CardReader(s)

Every one seems to be fine, except the USB Device, as marked, has a "!" with it. I tried to reinstall that driver, but in the end of the installing process, it said:

    An error occurred during the installation
    of the device.

    The installation failed because a function
    driver was not specified for this device

What is wrong and how to fix ???

I am using Celeron 833 (I think) with 128 MB RAM;
The OS is Windows 2000 professional English version

you need to remoce the driver completly and device out of windows,

then you need to search the net for the most up todate drivers for OS 2000 professional.

the drivers your using are not liking win 2000


or you cut get a LARGE pair of scissors and cut the CD in half and bin it.

fdisk the drive

and go back to win98. you'll find itll worth with that no problem :op

only joking about cutting ya cd up

Have you tried updating the USB device from the scanner CD. Some USB devices needs the accompanying device drivers from the manufacturer. In your case, try looking for the drivers from the Scanner CD not from Windows drivers (the drivers are for the root hub)

seen this many times & usually one of two things

1. Using the wrong drivers
2. Not compatible with operating system

Does the packaging say it is Win2K compatible ?

Just been to the above site & yes it is Win2K compatible

In your device manager is there anything listed under Imaging Devices ?
shaharidzal may be on the right track here. try to update the driver for the item listed as a USB device but choose select from list rather than having windows detect it.
choose category imaging devices then browse scanner CD to the Win2000 driver folder

A good number of USB devices prefer their "driver" programs be loaded before you plug in the USB device.  Following the manufacturers instructions is of utmost importance, especially when trying to configure USB devices.  I would unplug the scanner, remove the software and reboot.  Then, I would try to load the drivers as most of these will tell you exactly when they are expecting to see the device plugged in.  Plug it in when prompted and follow the onscreen directions.

These are the directions for the 7600, but most USB devices behave the same way.  Take a look on your "README" file and see if it is similar.  Like I was saying, INSTALL SOFTWARE then install Hardware.  You need to prepare your system for this sopecial configuration.  I consider it special as the USB port is being assigned properties normally associated with other port types in your system.  I have been using USB devices for over two years now and they all recommend that the drivers be installed prior to hardware,  This hold true for the following devices I have installed on my systems, Game controllers, Scanners, Camera, Network adapters, disk drives and USB speakers.  As you can see these devices normally would all use a seperate port.  With USB the USB port has to be configured to act like the port that it is being used instead of.

Hi all,

Thank you all very much for your precious comments. The problem has been solved, after spending 1.5 hr on the phone with the technical team of visioneer.

This is how it works :

======[ Problem solving for the Visioneer PhotoPort 7700 USB scanner ]======

1) In the Device Manager uninstall the following items:

   -!- USB Device  <--- ****
   --- Visioneer PhotoPort 7700 CardReader(s)
   --- Visioneer OneTouch 7700 internal Hub

2) Now, make sure you can view all of the files including Hidden and System files:

  >From the Tools Menu select Folder Options ---

   Click the View Tab;
   Make sure "Show Hidden files and folders" has a dot in front of it;
   Make sure "Hide file extensions for known file types" does NOT have a check mark in front of it;
   Make all necessary changes and click Apply then OK button.

3) Go to the INF folder of your Windows folder (lets say, c:\winnt). Delete the following files and folders, if any:

   c:\winnt\inf\VIZPNP (Folder)
   c:\winnt\inf\I386 (Folder)

3) In the same folder:

   1. click on Search icon.
   2. Under "Search for file or folder names " enter *.inf
   3. Under "Containing text" enter visioneer
   4. Make sure "Look in" shows c:\winnt\inf
   5. Click the "Search Now" button.
   6. This will find all of the INF files associated with
      Visioneer. Delete all of the files found by the
      search feature EXCEPT for the apcompat.inf file.
   7. For every INF file there is a corresponding PNF file that must also be deleted.

4) Delete the folder "c:\winnt\twain_32\vizscan";

5) Delete all files in the folder "c:\winnt\temp" ;

6) Delete all files in the folder "c:\winnt\Temporary Internet Files" ;

7) Empty the recycle bin;

8) Do a disk cleanup on c: drive and delete unnecessary files (in my case I deleted all files);

9) Unplug the USB cord of the scanner, and disconnect the power line of the scanner (yes, both);

10) Reboot;

11) After the rebooting, click and run the file F:\ScanSoft\Drives\7700.exe --- when it is asked to plug in the scanner, plug in the USB cord first, and then connect the power line of the scanner.


This protocol takes less than 10 min and it does work --- about 20 min after I got it to work, the scanner suddenly lost connection again in the middle of a scanning. I followed the procedure above and got it back alive again. It has been working properly since then ( > 36 hrs now).

It looks like that the problematic driver I mentioned above,

   -!- USB Device  <--- ****

is NOT needed for this scanner to work properly.


The CD that came with the PhotoPort 7700 is completely different from the CD you mentioned (the one for 7600);

I had the same problem with my HP 3970 scanner, it shows yellow mark on USB and when i wanted to update the driver it gives the error message saying

The installation failed because a function
    driver was not specified for this device

The simple solution to this is

1) Uninstall the Driver
2) Goto program files and manually remove the installation (eg Hewlett Packard) folder
3) Goto %systemroot%\winnt\inf folder which is hidden so click tool view select show hidden files and folders
4)remove all files related to the device eg search for hp*.inf
5) disconnect the power supply to the device ( scanner or any other USB device)
6) restart the PC and now connect the USB device it will be detected and instal the software

let me tell you one thing this problem is not with the driver CD from the company and 100% it  works
