ACR122U NFC Reader and HceDemo example

[etrau...@gmail.com]

Hello all,

I recently aquired an ACR122U NFC reader, and when I tried to run the HceDemo code, I got this error:

Exception in thread "main" java.lang.IllegalArgumentException: No supported card terminal found. Available Terminals 

at org.nfctools.scio.TerminalHandler.getAvailableTerminal(TerminalHandler.java:59)

at org.nfctools.examples.TerminalUtils.getAvailableTerminal(TerminalUtils.java:34)

at org.nfctools.examples.hce.HceDemo.run(HceDemo.java:10)

at org.nfctools.examples.hce.HceDemo.main(HceDemo.java:16)

I'm currently using Ubuntu, and I've already installed the "pcscd" and "pcsc-tools" packages, as well as the drivers from the official website (http://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader/).

I also ran the "sudo modprobe -r pn533" command to disable the kernel's default NFC drivers, and disabled them in the "/etc/modprobe.d/blacklist.conf" file.

When I run the "pcsc_scan", it results in the following output:

PC/SC device scanner

  Card state: Card removed,

  

This seems to indicate that the computer recognizes the reader, and so the problem may not be hardware related.

On the other hand, I also created a simple application to list the available terminals, like it was suggested in (https://groups.google.com/forum/#!msg/nfc-developers/HR4kXtnOuZQ/MoBzmNKZEo0J), but unfortunately, the result came up empty.

Until now I have found no additional workarounds to solve this problem.

Do any of you have any idea about what could be causing this issue?
