Removing/inserting YubiKey NEO works fine for me with GnuPG 2.0.x from
Jessie.  Could this be a GnuPG 2.1.x issue?  Lance, did this work with
older GnuPG versions?

I've seen the error many times, also when I used a g10code smartcard,
but lately things have been smooth.  I think there have been a couple of
gpg-agent/scdaemon fixes going in to make unplug/insert resume fine.
