The result above was while the NFC was within range of reader.  Here's the result when it's not:

$ sudo nfc-list
nfc-list uses libnfc 1.7.0
error	libnfc.driver.acr122_usb	Unable to claim USB interface (Permission denied)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:020:005
error	libnfc.driver.acr122_pcsc	No ACR122 firmware received, Error: 80100016
nfc-list: ERROR: Unable to open NFC device: acr122_pcsc:ACS ACR122U

So it seems there's some kind of communication going on?
