Support for CCID USB readers #60

Closed drebes closed 1 month ago

drebes commented 1 month ago

I have a Sony CCID based NFC reader. Being CCID, it is supported by libnfc (as of 1.8.0) if libnfc is compiled with the pcsc driver (./configure --with-drivers=all since by default the pcsc is not included in the default driver list)

Would it be possible to include the PCSC driver to support CCID based readers like this?

I just saw wizzomafizzo/tapto#4 which I see is related. As noted above there's a driver for pcsc in libnfc but it's not compiled by default. When using that driver there's no need for a connection string.

Hi. I have not been able to compile libnfc successfully myself with pcsc enabled, for some reason it will not link to libpcsclite. I've attached a version of tapto compiled against the stock libnfc in ubuntu, which I think includes pcsc support. You're welcome to try it out! I haven't had much luck with it myself

Thanks, I'll give it a try. I'll try to setup an environment to try to compile it myself but that may take a bit longer.

I managed to compile it with pcsc support and have the reader detected, but so far only when running tapto on a Debian VM. But I get Last scan: never despite putting tags on the reader, I may be missing something.

I think I'm having issues with libnfc and this reader. While it detects the reader it has trouble reading cards. I'll close this for now and reopen once I have sorted this out.

The PCSC driver lacks an implementation for InitiatorPollTarget/initiator_poll_target, which explains I couldn't read my tags with the reader. I could only read my tag with InitiatorListPassiveTargets.
