If you enter "scd help getinfo" you can see this in the scdameon log file:

: chan_10 <- # reader_list - Return a list of detected card readers.  Does
: chan_10 <- #               currently only work with the internal CCID driver.

Thus it does not work with pcscd.  To convince pcscd to use the second
reader you need to use the 

  reader-port "REINER SCT CyberJack pp_a"

or a bit more of the string shown by opensc-tool.  I am not sure how it
formats the reader description.  Scdaemon compares the reader-port
against the reader description as returned by pcsc_list_reader.

The problem with pcsc is that we need a wrapper on most system and this
wrapper does not return the list of readers.  We have plans to drop this
wrapper in 2.1.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
