Hi!
First info: pscs-lite-1.0.0B, towitoko-2.0.4
I cannot read a memorycard, i always get the message "Transaction failed"
after calling SCardTransmit.
Writing to the memorycard goes OK!
If i use the test-program (ctapi) shipped with the towitoko-driver, reading
and writing is possible.
I spent already a lot of time trying to run pcsc with my towitoko-reader, but
with
less success. First I struggled with the protocol (SCARD_PROTOCOL_RAW or
SCARD_PROTOCOL_ANY), now I am hanging with this problem.
I hope the community can help me.
Thanks in advance
Andi
