Is the gpg-agent running?  Run "gpg-agent" and it will tell you.

Is the scdaemon installed? Run 

   gpg-connect-agent 'SCD getinfo version' /bye

This should display the version number of the scdaemon. Check
permissions of the reader (/dev/bus/usb/NNN/MMM), you need to have write

If that is all fine, you need to enable debugging: Add these lines to

  debug 1024
  debug 2048
  log-file /foo/bar/scdaemon.log

Restart scdaemon (Use "kill" or with the latest GnuPG versions: 
"gpgconf--reload scdaemon").



Die Gedanken sind frei.  Auschnahme regelt ein Bundeschgesetz.
