GnuPG 2.2 only supports a single token with PC/SC.  But, with the
internal CCID driver, multiple tokens are supported.

If 'gpg --card-status' shows your reader like:

    Reader ...........: 234B:0000:FSIJ-1.2.15-43225368:0

(i.e., USB VID:PID:SERIAL-string:0), then, it uses the internal CCID
driver.  If not, it is through PC/SC.  If there is no specific reason to
enable PC/SC service (for example, other usages for other cards), you
can disable it so that the internal CCID driver will be selected.

GnuPG 2.3 will support multiple tokens with PC/SC.  The ticket to track
this feature is:

Including this improvement, there will be more in GnuPG 2.3.  It is
listed at:
