I agree. I decided to test again using an FreedomBox image to reduce the difference since my initial testing. First I tested using version 2.1.11-7 in Debian testing, and then using version 2.1.14-1 in Debian experimental. Both fail. First the test using testing. fbx@freedombox:~$ cat .gnupg/scdaemon.conf debug-level guru debug-all debug-ccid-driver log-file /run/user/1000/scd.log verbose fbx@freedombox:~$ touch

I've tried all three adjustments, did not make a difference. :( I bought the the card and reader I am using from <URL: http://shop.kernelconcepts.de/ >.
