What steps will reproduce the problem?
1. git clone nfclib / compile / install / test

#nfc-list 
nfc-list uses libnfc libnfc-1.7.0-51-g7b7f506
NFC device: SCM Micro / SCL3711-NFC&RW opened

      SAK (SEL_RES): 88

>> nfc lib is working

2. git clone mfoc / autoconf / make
3. run mfoc

What is the expected output? What do you see instead?

I did some further investigation.

If I blacklist linux modules 'nfc' and 'pn533' everything is working.
If I load linux modules 'nfc' and 'pn533' and unload it, i have this issue.

pull off and plug in of usb-dongle can repair this behavior.

Another possibility to trigger this issue is to cancel the computing on keys.

>> conclusion: it seems the dongle isn't setup correctly and shutdown on 
program end.
>> don't know if it is a mfoc or libnfc task
