Hello, I am quite new to working with Chipcards and drives, so please excuse if I'm not too familiar with any general problems and their solutions. OK, I am trying to read and write memory cards using SuSE Linux, Kernel 2.2.13 or 2.0.36. I am using the latest Towitoko CT-API. Unfortunately I am not able to read or write any data from or to the mem card. I am using Towitoko's "Chipdrive extern". The problem is, that I get no response on the reset command. Because, as I have seen, it is sent before any other command, I can't do really anything with the drive. Unfortunately it works wwell under Windows :-) , so there's no defect. I also tried the "tester" program coming with the CT-API und used another "cttest" program for testing the CT-API, they both have the same problem. Symptoms: CT_init() is working well, and also the GetRdrStatus(), setting the LED and ActivateCard(). They all receive an answer from the drive. But when a reset is sent (with answer requested), the drive is not answering. I have debugged it so far and the command is sent, but the select()-command is just timing out, because there never comes an answer on the reset. Has anybody had a similar problem? What am I doing wrong?!? Here is the test protocol: CT-API Library Test Loading CT-API library (libctapi-towitoko.so): Ok. Initialising CT-API library:Sending: 0 1 -> GetRdrType Receiving: 84 43 93 ---- Reader type: 0x84 Ok.
