Exactly what wangweij says. Checking the instance is fundamental to find out the real cause. Especially because `PCSCException` is thrown not only on PCSC errors, but also on internal module errors.
In this case also the error messages of `CardException` are not really helpful. (`CardException: list() failed`)
The suggestion to extend the constructor sounds reasonable for me.
