Smartcard USB application

Hello,
Im writing a usb communication tool on the LPC2368 for smartcard devices. I still don't get any communication between the host and the smartcard device for couple of weeks know. It seems like the program is be missing something and i dont know what.

Do you Know where I can find any smartcard USB application for arm7 microcontroller?

Can anybody help me on it? If necessary I will post the fully commented code that I have written.

Thanks in advance

Hello Tsuneo,
thanks for your quick reply.
Yes I have verified the reader is bus-powered!
Here the definition of WBVAL1:

#define WBVAL1(x) ((x >> 24) & 0xFF), ((x >> 16) & 0xFF), ((x >> 8) & 0xFF), (x & 0xFF) //DWORD to 4 bytes

Talking about the endpoint configurations, I leaned on that fixed endpoint configuration of the LPC23xx manual but I refered to the physical Endpoints (second column) instead of the logical ones. Hmmm. I will try now to follow your recommendations and reconfigure the endpoints accordingly. I will let you know throughout the day whether any change happens.
Here is the definitions of the endpoints events. I wondered why the Programm doesnt reach the configured endpoints!

Im very grateful about the fact that you spend your time trying to release me from a problem that seems to try to bring me down!
Thanks a lot Tsuneo!!

#define SMARTCARDCONTACTLESS_PROT 0x00010000

This is for contactless protocol.
see www.pcscworkgroup.com/.../pcsc3_v2.01.09.pdf page 17.

Now I will try 0x00000003 (for T=0 and T=1)

Thanks
