Access Denied on before IRP_MJ_CREATE

NTDEV
1

Hello Everybody,

I have another question about driver development. I have a smartcard
reader based off the toaster samples. on windows 2000 the driver works fine
but on windows XP i suddenly get an access denied error

(SCardSvr!AddReaderDriver *ERROR* WDM Reader driver initialization cannot
open reader device: Access is denied.)

Where the IRP_MJ_CREATE callback should be called. What am I missing?

Best regards,
Rikki Tamayo

Oops… My Bad, I found out that changing the Call to IoCreateDeviceSecure to
IoCreateDevice in the bus enumerator fixed this… Sorry…

Best Regards,
rikki
