neard: nfctool does not find ACR122U

[Rainer Dorsch <ml@bokomoko.de>]

Hello,

I am wondering if I am doing something wrong with neard/nfctool: I have 
attached and ACR122U using USB. dmesg finds it, lsusb as well. When an NFC card 
is in reach of the reader, the reader even magically beeps and the color of 
the LED changes from red to green.

But nfctool does not seem to find it (at least the empty Devices section 
implies that(?))...

Similarly, I see that nfcpy also has problems

rd@h370:~/tmp.nobackup/NFC/nfcpy/examples$ ./tagtool.py 
[nfc.clf] searching for reader on path usb
[nfc.clf] no reader available on path usb
[main] no contactless reader found on usb
[main] no contactless reader available
rd@h370:~/tmp.nobackup/NFC/nfcpy/examples$

but I think the problem is in the area of neard...

Documentation in the NFC on Linux area seems to be sparse, so any hint is 
welcome...

Thanks
Rainer
