I am currently backporting the SCD changes in master branch to 2.0.

For this particular issue, I believe that it has been fixed by the
following commit, which was included in 2.0.18 already.

    Fixed problem with unplugging card readers.
    
    From Grant Olsons's mail to gnupg-devel@:
    
      This is three-quarters NIIBE and one-quarter me, but I though it would
      be easier to have a single complete patch that applies to
      STABLE-BRANCH-2-0 than two patches floating around.
    
      This is basically NIIBE Yatuka's patch here:
    
      http://lists.gnupg.org/pipermail/gnupg-devel/2010-November/025828.html
    
      Plus another check that closes down the reader explicitly if we get a
      SW_HOST_NO_READER error, so that an unplugged reader doesn't hold onto
      the first slot, preventing us from getting to the active plugged reader.
