Perhaps, a suggestion for Lucisusman:
On the SteelChn thread (very long) :
Unoffical Vista X64 driver of LS-8000ED/9000ED for Nikon Scan 4.03 - Photo.net Digital Darkroom Forum
http://photo.net/digital-darkroom-fo...Ryck?start=120
a user explained that he had to modify the .inf file already modified by SteelChn,
in order to make his scanner work.
SteelChn, then, "officialy" added this modification in his own version.
I think that the .inf file quoted in this thread is now the last version, but I am not sure.
In this 'last' version, mark
'Nikon LS-50' (for mark V?) as mark 'Nikon LS-40'
are mentionned in the [Models] section.
The user made a "copy" from a section [Models] to a section [Models.ntamd64]
or, may be, he added new lines for 'firewire' scanners (for a LS-4000 model, I don't remember precisely).
However, it is not clear whether the scanners have to be declared in the 64 or in the 32 (default) section ?
For reason of compatibility, the driver is to be put in x86 driver directories, so 64 seems not necessary...
For my scanner LS-5000 it worked with the declaration in [Models.ntamd64] section, but I am not convinced it is necessary. Some of the problems I mentionned on W8 (which adds constraints with signed option activated) are perhaps due to that.
For instance, Nikon LS-40 is in the [Models] section, and it seems to work. And it is also in the [Models.ntamd64]
section !
Perhaps Lucisusman has to check that he has the 'good' [last] version for .inf.
In addition, he has to use the NikonScan
4.0.3 driver ( NKScnUSD.dll ? or the very one corresponding to his model)
Perhaps Lucisussman could try the .inf version without modifying it, that is, with driver declared only in the section
[Models]
"Nikon LS-50" = USBScanner,USB\Vid_04b0&Pid_4001
and if it doesnot work, put it in the
[Models.ntamd64]
"Nikon LS-50" = USBScanner,USB\Vid_04b0&Pid_4001
removing the corresponding line from [Models] section
(perhaps, only the first encoutered declaration is really taken into account,
or double declaration may be a problem in some circonstances ???)
I hope it will help.
Without any guarantee, but it's not long to try it, and it worths it.
