Topic: [SOLVED] Why nfc-list only works with sudo using PN53x USB device ?
I downloaded, built, and installed libnfc-1.6.0-rc1 on Ubuntu 12.04 LTS. All the utilities worked just fine. i.e. I can do "nfc-list" to see the NFC reader and tag info.
Then I downloaded, built, and installed latest development tree of libnfc from yesterday (Nov 11). In this case, nfc-list only works with sudo. i.e. I have to do "sudo nfc-list" for it to show NFC reader and tag info. If sudo is not used, it will always say "ERROR: Unable to open NFC device".
Anyone knows why this is happening?
