Accessing the 2nd card reader

[Richard]

Hello everyone,

I have connected two card readers to my computer, but want only to use
the 2nd one with GnuPG 2/scdaemon.
Both are PCSC readers:

$ opensc-tool -l
Readers known about:
Nr.    Driver     Name
0      pcsc       SCM SPR 532 [Vendor Interface] (21250837209929) 00 00
1      pcsc       REINER SCT CyberJack pp_a (8928928328) 00 00

However, GnuPG only recognizes the 1st reader:

$ echo scd getinfo reader_list | gpg-connect-agent --decode | awk
'/^D/ {print $2}'
04E6:E003:21250837209929:0

How can I force GnuPG to use the 2nd reader only? I don't know what
which reader-port option to set in ~/.gnupg/scdaemon.conf.


Thanks,

    Richard
