Yes, I've been manually changing the permissions on the device nodes to
give the scard group (of which my user account is a member) read-write
access. But this hasn't changed anything. (Running using sudo has the
same output with the addition of a line warning about ownership of

Yes, I've tried pcscd. Sadly the licence of the driver for my smartcard
reader is unclear (the LICENCE file is missing from the download .zip
file). The card was certainly detected by pcscd but I had problems
completing very basic steps - pcscd segfaulted when I tried to set my
name on the card.
So I wanted to see if I could get the gpg internal system working as
(potentially) the easiest route!
