Update USB Drivers to the Windows System Directory

NTDEV
1

This may be a pretty basic question but my understanding of usb drivers is
limited.

I have an installation that preloads an .inf file and that .inf file loads
the usb drivers when needed to the Windows System directory. (I know in 98
you can just copy straight to the system directory but not in XP.) This
part works without a glitch. When an older version of the driver exists, it
copies the new drivers to the company folder C:\Company\Usb_Drivers (in
doing so updates the older drivers). This new version of drivers never
makes it to the systems directory. It seems like windows has a driver that
works so it fails to re-copy (or re-read the .inf) the drivers to the
systems folder.

Is there a way to get the new files updated to the system folder? I tried
updating the .inf file but that doesn’t seem to work.

Any suggestions would be greatly appreciated.

Thanks!!

Hmmmm… Do you have a DriverVer directive in your INF?? In theory, if you change the DATE in DriverVer (note that the x.y.z.a version NUMBER field doesn’t matter), you should get the new driver installed.

Also, be sure to run your INF through CHKINF to find any other weird glitches that might be playing a part.

Peter,

Thanks for the suggestion. There wasn’t a version directive in the old .inf
file and when I add a version directive with today’s date it doesn’t seem to
do anything. It doesn’t ever update the systems directory.

Is it a problem that the original had no version directive in it?
