Well it helps by saying that everything is installed as it should be but wont fix your problem.
The only thing i can think to try is update debian then reinstall pcsc lite or the reader itself is faulty, if you want to try do this.
Logged in as root user
Reboot server then on restart
Then install as you did previously, if the reader is good then i guess alot of searching the error codes are the way to go unless another member has experienced this problem before.
