Topic: "Error connecting NFC reader" using ACS ACR122U PICC

Hi,

I would like to use libnfc with an "ACS ACR122U PICC" interface under GNU/Linux.

Actually I use GNU/Debian in Lenny version, I had installed ccid 1.3.10 and pcsc-lite library 1.5.2. Compilation works fine but when I launch one of provided tools (i.e. ./list) to test libnfc, it outputs "Error connecting NFC reader".

Before posting here, I had tried to use pcsc-tools (pcsc_scan) and I can read MiFare tags but only with pcsc-lite suite >= 1.5 but even I compile libnfc against pcsc-lite 1.5.2, libnfc seems to not find my reader.

Any idea to be able to use libnfc using this hardware under Linux ?

PS: My reader have value "bcdDevice" = 2.05 in `lsusb -v`, according to http://pcsclite.alioth.debian.org/reade … _PICC.txt, "bcdDevice" seems to be firmware revision.

Self reply...

As Roel says on http://www.libnfc.org/community/post/34/#p34, I must put tag BEFORE trying to list them...

Sorry for annoying.
