Topic: CP210x Support (TRF7960)

I own a TI TRF7960 RFID reader.Linux recognizes the device

[294036.567561] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0
[294036.567574] cp210x 6-1:1.0: device disconnected
[294038.163988] usb 6-1: new full speed USB device number 9 using uhci_hcd
[294038.325680] cp210x 6-1:1.0: cp210x converter detected
[294038.430646] usb 6-1: reset full speed USB device number 9 using uhci_hcd
[294038.570811] usb 6-1: cp210x converter now attached to ttyUSB0

lsusb shows it as

Bus 004 Device 032: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device

and it is useable through a python script using the serial device.
In this post someone asked for help using this device and it seemed to work for him
http://www.libnfc.org/community/topic/2 … buntu-904/
When I try nfc-list I only get

nfc-list uses libnfc 1.5.1 (r1175)
No NFC device found.

I tried the newest svn release too.
I build the code with
./configure --prefix /usr --enable-serial-autoprobe --with-drivers=acr122,arygon,pn53x_usb,pn532_uart
and strace shows that it probes on some ttys including ttyUSB0.
I don't get why it does not work.Hope somebody here can help.

This device is not supported by libnfc so you have to implement a driver for it in libnfc to drive it using this library.
