Hello,
I’m trying to install my driver for AMCC5920 PCI card. The code is very
simple, it just gets the resources in irp_mn_start_device routine & doesn’t
do anything. I get the error from device manager while installing ; “This
device is not working properly because Windows cannot load the drivers
required for this device. (Code 31)”.
I searched in the registry , the registry settings are fine; it doesn’t
contain any entries like upperfilter & lowerfilter.
Then I tried with the AMCC driver which is available on osr site, it is also
giving me the same error. I also tried the sample driver which comes along
with the book “Programming WDM”. However there is no sucess. Everytime I get
the error in loading the driver.
What I understand by driver loading is that it maps the driver’s image into
virtual memory, fixes up references & calls driverentry function. I’m not
understanding what is wrong in my case.
Please help me to solve this problem. Is it necessary to initialize some
registers of AMCC ? Or Is it a problem of .inf file specification ?
Thanks & Regards,
