The problem is that I keep getting a "The device cannot start (code 10)" message after each and every time I install the driver.
I have noticed in "Driver Details" that I have three files from the c:\windows\system32\drivers folder, namely ksthunk.sys, usbscan.sys & LVUSBS64.sys. Could someone please advise if these are the correct files? Should I be seeing NKSCNUSD.dll in there?
I should say that the scanner works perfectly under windows XP on my old PC, so no problem with the hardware.
Any advice and help would be appreciated.
I gather that where you are looking for the Driver Details you mention is in the Device Manager, Under Imaging devices, look at the properties of "Nikon LS-40", click the Driver tab, and then click on the button labeled Driver Details? I just want to be sure we're talking about the same thing.
I have a Coolscan IV running the Nikon software under Win8-64bit. It should be very, very similar to how it would look in a Windows 7-64 system like yours. When I look at my Driver Details it lists only two files, both in the c:\windows\system32\drivers folder, namely ksthunk.sys and usbscan.sys. No mention of LVUSBS64.sys or NKSCNUSD.dll so to answer your question, no I don't think you should be seeing either of those files listed there.
My copy of the file NKScnUSD.dll is stored in C:\Program Files (x86)\Common Files\Nikon\Driver\ScanUSB. Also in C:\Program Files (x86)\Nikon\NkScan4\Nikon Files, which is also the folder where I placed my scanners.inf file.
I don't have the file LVUSBS64.sys anywhere on my system. I googled for it and it seems to be a device driver for Logitech hardware. It certainly shouldn't be showing up in your Nikon driver details. I don't know why it is but I think that is the root of your problems getting your Nikon scanner working.
