Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. executing bundled nfc-list
or
2. calling nfc_open() in the library

What is the expected output? What do you see instead?
nfc-list uses libnfc 1.6.0-rc1 (r1463)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:001:006

What version of the product are you using? On what operating system?
Ubuntu 12.04 64-bit

Thanks for reporting.
BTW, it seems to be the same problem than Adam:
http://www.libnfc.org/community/post/3763

FYI, acr122_usb is a new but experimental driver for Touchatag/ACR122U devices.
The goal is to be able to abort command and bring timeouts in addition to 
remove PCSC dependency if user want to.

So you can use acr122_pcsc driver if you need the old driver:
./configure --with-drivers=acr122_pcsc && make clean all

hmm, when I run nfc-list as root, it works. But before that, I have also 
restarted pcscd, so this may be indeed related to Adam's problem. I will try 
the same thing out tomorrow without restarting pcscd.

Even after restarting pcscd, libnfc will not run correctly when not running as 
root. Will try --with-drivers=acr122_pcsc option

Have you installed udev rules? That fixed the root/non-root issues for me.

Running ./configure --with-drivers=acr122_pcsc && make clean all fixed this 
issue for me on Mac Lion
