[Muscle] Weird problem with PCSC

[prakash ns]

Hi everyone,

I am using a SCM SDI010 Reader to interact with a JCOP 21 card.

> I have interfaced the USB smartcard reader with my application.
> Iam using pcsclite-1.2.0 with 2.4.20-8 kernel.
>  I am able to read and write from the card at low level.
> I have interfaced with the application but the reader responds to
 some read or write calls from the application and gives me the problem of
 insufficient buffer which i am unable to debug.
>If i change any particular variable, say i declare an integer then
it works fine.

I dont understand how a declaration of a variable which is not used
anywhere else in a particular function helps in solving the problem.
I have tried all versions upto pcsclite-1.4.4.

Please do suggest a solution.

cheers,
