Topic: [Solved] Install problem of libnfc with ACR122U
Hello, I have a problem with the installation of libnfc on Raspberry Pi (Raspbian).
I use ACR122U reader.
This is what I do:
tar -xvf libnfc-1.7.1.tar.bz2 cd libnfc-1.7.1/ ./configure –with-drivers=all make sudo make install cd utils/ sudo nfc-scan-device
and I have the following problem:
nfc-scan-device uses libnfc 1.7.1 1 NFC device(s) found: error libnfc.driver.acr122_usb Unable to claim USB interface (Device or resource busy) nfc_open failed for acr122_usb:001:011
I tried to install :
latest version of pcsc-lite
but it still does not work
do you have an idea ?
