Could you post a debug log of libnfc detecting and initializing the device? (I've never heard of an ST-Ericsson PN533 based reader, btw.)

Hi,

first thanks for your reply. I'm very new on nfc (and pretty new on Linux) and don't know where to find the debug log of libnfc, but I would be glad to give you all information, if you tell me where to find it. I hope the following information can help you.....

Bus 007 Device 015: ID 04cc:2533 ST-Ericsson NFC device (PN533)

Unfortunately, I couldn't find a non-german distributor of this dongle, but here is the link to where I got it (english): http://www.nfc-tag-shop.de/nfc-hardware/21/nfc-usb-stick-nxp-pn533-reader/writer

I also asked someone for some help and he “debugged” your code, building checkpoints (like “print “<X>”) on some places. He said your code seems to be ok and the error(s) seems to be in pyUSB. Here's your modified code (and after that the output):

This is indeed a standard PN533 device (the USB Vendor ID 0x04CC was owned by Philips years back).
Please run "examples/tagtool.py -d nfc.dev" and post the output.

Please use an unmodified version of the library. The statement "found = [(1228L, 9523L, '007', '031')]" inserted in function connect(path) causes confusion when later iterating the usb devices (because the device id changes every time the device is plugged in)

It looks like the EEPROM is not accessible (or just not present for cost reasons). Though an appropriate error response I've would have expected from the chip. Anyway, I've ordered the same reader and will check that if it arrives. For the time being you could try to replace lines 639-650 in nfc/dev/pn53x.py with the following:

device._vendor_name = "NXP"
device._device_name = "PN533"

The output seems to be infinite, stops when the tag was removed and continuous when touch again. Brake just with Ctrl+C.

Next days I should get Mifare Desfire tags. I will post what happen using them.

The output seems to be infinite, stops when the tag was removed and continuous when touch again. Brake just with Ctrl+C.

Next days I should get Mifare Desfire tags. I will post what happen using them.

Mifare Classic tags are not supported by nfcpy, that's why you see the format error reported. Any NFC Forum compatible tag should do - that's Ulralight, Desfire and NTAG if just speaking about NXP.

Hello,

I have the same device and I have the same problem reported in the first post.
I did what Stephen sugested (replace the lines) but then I didn't have success as xiF running "python examples/tagtool.py -d dev.py".

Can you confirm if are these the lines to change please? http://imageshack.us/content_round.php?page=done&l=img853/7970/sld8.png

Hi,

I replaced ALL the lines 639, 640, 641, .., 650. Just delete all (or comment) and copy the lines above.

Also, Desfire tags are recognised without problems. Great work!

The issue is now fixed since revision 202, the modification in pn53x.py is no longer needed.
You can use "bzr revert nfc/dev/pn53x.py && bzr pull" to upgrade.
