By default we are not using PC/SC on Linux but direct access to the
reader via USB.  Now if pcscd is already running and has access to the
reader scdaemon won't be able to access the reader via USB.

2.2 falls back to PC/SC if it can't use the reader via USB.

Either shutdown pcscd or add


to ~/.gnupg/scdaemon.conf

More debug output can be logged by adding

debug cardio
