I am trying to install a LiDE 30 USB scanner on an IBM NetVista PC (P4 1.8 mhz, 256 MB RAM, Windows 2000 Professional, Service Pack 4). I had previously installed a Canon N1220U USB scanner on this same PC. When I installed the new scanner, it would not connect to the applications.
Under device manager>imaging devices, there is a yellow circle with an exclamation mark. Under properties, I see the following error message: This device is not working properly because Windows cannot load the drivers required for this device. (Code 31).
I have tried multiple solutions, so far without success. I have searched the Canon support site and also the Microsoft knowledge base and have been unable to find any information that specifically addresses this problem. The scanner is unlocked and it functions normally when connected to my HP laptop computer.
I tried uninstalling the scanner via device manager and reinstalling. I have also tried multiple variations of uninstalling everything and then reinstalling, with reboots after the deletes, and also after the installs. I have also deleted all the files in the temp directories.
I have downloaded the Canon deldrv utility and deleted the drivers for both the N1220u and the LiDE 30, and deleted all the Canon applications. I then reinstalled the drivers for the LIDE 30 from CD, rebooted, and still get the code 31 error in device manager. I tried cleaning everything off again, and installed the latest drivers from the Canon web site.
I feel like I must be missing something here. Is there a registry key that is preventing the driver from loading? I think there must be something else that needs to be removed before I can successfully install this scanner.
