versions puzzle with mifare card reader

[toni incog]

Hi,
I have a  working acr122U usb card reader @bbb|g:

1.bbb, wheezy, kernel 4.1.18-r56
2.bbg, wheezy, kernel 3.8.13-bone71.1 (ex works Debian Image 2015-03-01)

with following recipe:

modprobe.d/rfid-blacklist

blacklist pn533
blacklist nfc

apt-get install libpcsclite1 pcsc-tools pcscd libacsccid1

nice. 

But now I pimped a bbg to jessie and latest kernel and it fails:

sudo pcscd -f  --error 
00000935 ifdwrapper.c:371:IFDStatusICC() Card not transacted: 612
00000555 eventhandler.c:233:EHSpawnEventHandler() Initial Check Failed on ACS ACR122U 00 00
00000514 readerfactory.c:361:RFAddReader() ACS ACR122U init failed.
00042066 hotplug_libudev.c:501:HPAddDevice() Failed adding USB device: ACS ACR122U
03016030 ccid_usb.c:798:ReadUSB() read failed (1/4): -7 Resource temporarily unavailable

Seems the only diff is jessie vs wheezy. But somehow it can't read the usb like the blacklist didn't work.

Ideas? I'm out of.

fired-up an amd64 jessie and that is working even without libacsccid1, puzzling.

Maybe another option is to use libnfc? IIRC, that was all user space and didn't require the kernel driver.

pcsc-lite is a userspace solution, the blacklist is to prevent kernel modules interfering. It's libnfc that's using the kernel drivers?
Anyway, thanks but I can fall back to wheezy. Just curious where it goes bananas. Now trying latest 'offical' jessie release.

google asking me to post again? I really don't get this webbased eventually inconsistent crap. And why 2 post buttons.. Well here we go (again)

Ah ok. I've been playing around with the Adafruit PN532 breakout shield
and their FDTI cable (not on a BBB, but soon I'll migrate to that) with
libnfc.

The card emulation example worked which was cool. I have a low
expectation of nfc things working on linux though :)

My use case is pretty simple, read a NDEF text message from a forum 2
tag and write a NDEF text message to a forum 2 tag.

This info may not be interesting/helpful to you but I've encountered
few NFC hackers out there so I'd figured I'd share.

Yeah, google groups :( If you subscribe you can pretty much respond to
mail the old fashion way in a old-school mail client though and not
bother with any of the google stuff.

For simple read/write via java pcsc-lite works like a charm for mifare
cards. It only takes a lot of time to figure out those silly protocols.

That is a good idea! thx!

I now have tested/concluded that all jessie version are broken w.r.t.
acr122u. Somehow the driver (libacsccid1) isn't used..
