Hi,

I have been trying to figure out why I am getting "RPC transport error"
at "SCardEstablishContext" method call while running "./testpcsc".

But, I couldn't.

I am running "pcscd" before I actually run ./testpcsc.

I have tried recompiling the testpcsc.c as follows, "gcc -o testpcsc
testpcsc.c -L/usr/local/pcsc/lib -lpcsclite -I. -lpthread" but no luck.

When I run "pcscd -f -d stdout"

I've got the following output.

[rootautodial pcsc]# pcscd -f -d stdout

This is my /etc/reader.conf file.

FRIENDLYNAME "GemPC Twin"

DEVICENAME /dev/ttyS0

LIBPATH /usr/local/pcsc/drivers/serial/libccidtwin.so.0.9.3

CHANNELID 1

I have tried with 2 different card readers. But I'm getting the same
problem, i.e., "Testing SCardEstablishContext : RPC transport error".

What else could be the problem. Kindly let me know.

Cheers,

Naveen.
