driver cannot be loaded - code 39

kobi n

Hi,

i have a very strange situation that i can't seem to deal with.

my driver is WDF based. it's a pci card driver which is functioning well and
in the middle of the development. i use the 6001 package to build it and all
went fine until, whole of a sudden, my driver cannot be loaded. using WinDBG
i can see that DriverEntry is never called. it is very strange since i
havn't done any changes in the PnP sections of the driver and neither in the
..inf file.

the error i get from windows PnP :
windows cannot load the device driver for this hardware. driver may be
corrupted or missing.
THE THING IS : when i try it with some older version of my driver (again,
without any differences in the PnP sections) it works fine.


any ideas ?

thanks,
kobi

i would guess that you are using an export that is supported on one OS but
not another. What build window did you build your driver in? what OS are
you trying to load your driver in?
