What steps will reproduce the problem?
1. use 2 card readers. For example an Cyberjack e-com an an PN533 based device.

What is the expected output? What do you see instead?
expected:
./ifdnfc-activate 
Activating ifdnfc with "pn53x_usb:002:019"...
IFD-NFC is active using pn53x_usb:002:019.
get:
/ifdnfc-activate 
Activating ifdnfc with "pn53x_usb:002:019"...
Internal error.

What version of the product are you using? On what operating system?
Version: Last from Git.
OS: Fedora 20

Please provide any additional information below.
ifdnfc-activate will not search for the right reader.
It will only use the first reader. In this case the cyberjack.
By remove the first device, it will work.
