all functions run smoothly,nothing failed debug message showed

[Coslma]

where can i download ifdtest.exe?and how to use it to debug my virtual reader?

[PeterBritton]

Hello,

There is a useful looking smartcard wdk example that can be found at the following location of the wdk tree:

src\smartcrd\pscr

"pscrnt.c" contains example code for a lot of the IRP requests including Start - however the the code for start is dependant upon the device as to what needs to be done to start the device.

Hello,

sorry it doesnt appear to be working yet - writing drivers is an interesting challenge at times!
Sometimes you need to go through step by step making sure that everything is how it should be

Does AddDevice get called and complete sucessfully without errors?

Hello again,

Does the driver get to see any incoming operational commands - such as IRP requests?

Hello,

Thats great that its setting up symbolic links - but it doesnt answer why it isnt being seen in the list of available smartcard devices

Make sure that the smart card service is started

Use lots of kernel debug print statements in the driver code to display the error values that are being returned from the kernel API calls - and also see what return values that the driver is returning back to the calling layer.
