Topic: ACR122U with Mac OSX: unable to claim USB interface
I'm really new to this stuff and I searched the forums for this issue but the answers have been to complicated for a newbie. I'm trying to use ACR122U with Mac OSX. I installed libnfc via brew and also the latest drivers from the manufacturer.
When I run pcsctest everything is ok. But when I try to use libnfc (for example command "lsnfc") I get these error message:
error libnfc.driver.acr122_usb Unable to claim USB interface (Permission denied)
ERROR: Unable to connect to NFC device.
For me, it seems that libnfc is using the wrong driver but I don't know how to change it.
Hope anybody can help me.
Thanks in advance and have a nice weekend!
