Hi everyone,
I'm new to OpenSc and I'm trying to read (and write...hopefully) information from a blank card (if there is some information, like a RSA key stored).
I use a CASTLES EZ100PU and a SLE5542 blank card. OS: ubuntu.


when I send pcscan command the reader is detected:

Possibly identified card (using /usr/share/pcsc/smartcard_list.txt):

but when I send pkcs15-tool --list-keys command:

root <at> kiosk:~# pkcs15-tool --list-keys
Using reader with a card: CASTLES EZ100PU 00 00
[pkcs15-tool] reader-pcsc.c:199:pcsc_internal_transmit: SCardTransmit failed: 0x80100013
[pkcs15-tool] reader-pcsc.c:239:pcsc_transmit: unable to transmit
[pkcs15-tool] apdu.c:394:do_single_transmit: unable to transmit APDU

then, pcscan doesn't work anymore
