[pkg-gnupg-maint] Bug#854616: Bug#854616: scdaemon cannot access yubikey using ccid driver without pcscd

[Daniel Kahn Gillmor]

Control: tags 854616 + moreinfo

Hi Anarcat--

thanks for all this documentation on #854616.  I'd like to try to
differentiate this report from #854005.

#854005 is about problems with smartcards more generally.

The new bug, #845616, should be focused specifically on the use case
where pcscd is *not* involved (not even installed on the system), and
disable-ccid is *not* set in scdaemon.conf.

Can you confirm that:

 * disable-ccid is *not* set in scdaemon.conf
 * pcscd is purged
 * the same problem is present on 2.1.18-4 ?


Thanks,
