error libnfc.driver.acr122_usb Command Code verification failed

[Pebrok]

Hi,
I'm new to Libnfc.
I'd like to use my ACR122U to read (or more) badges and cards, and I installed Kali on a USB stick.
I start it on a pc on boot, and I installed everything, and it seemed to be working.

But everytime I do a nfc list , I got the following error message:
error libnfc.driver.acr122_usb Command Code verification failed

I believe I looked everywhere on the net, and tried a lot of thing, but couldn't find a fix.

Can someone help ?
As I am a newbie, I copy/paste code, so if anything more complicated is requested, please be patient.

Hi!!

[Gnu-Hack]

What command do you use?

Hi @Gnu-Hack ,
I've encountered similar behaviour.

The NFC reader/writer is ACR122U-A9 based on the P/N.

I'm porting this package to GNU Guix. I tried both GNU and CMake systems. The package builds in both but as I attempt to run the following command I get this error:

I've tried to blacklist the modules but that didn't help.

Also is it normal I hear some sound when the device activates? My guess is it's charging the coil or something like that.
After that the tiny noise disappears and the LED on the device is turned on (red/amber).

Hi!! have you installed the pccd drivers? what have you blacklisted? If the device has a red LED, it means that it is not correctly configured José CardeLL

Here's check for the pccd drivers - none loaded.

lsmod | grep pccd

Also not compiled into kernel

grep pccd -i /run/current-system/kernel/.config

Do you know which package they are part of? @Gnu-Hack

Maybe it's this one

[Gnu-Hack]

Install you (Debian) sudo apt-get install pcscd pcsc-tools After: sudo nano /etc/modprobe.d/blacklist-libnfc.conf And write here: blacklist nfc blacklist pn533 blacklist pn533_usb After do not restart, turn off and on if the red led has gone off it is good. then check with the following: sudo nfc-list -v nfc-scan-device nfc-list pcsc_scan José CardeLL

Okay, I'll test it on Debain tomorrow to see if the issue is the device itself or me packaging for GNU Guix.

However, these steps I already applied. But it might be the way how Guix is structured that it might need some patch.

Nevertheless thanks for the support!

[Gnu-Hack]

OK we talk tomorrow José CardeLL

Hi, yes I ran the commands on Fedora.

The libnfc does not work there either.

However I've been able to read the cards using pcsc_scan after blacklisting the modules.

Therefore the NFC reader/writer device is functional.

Regarding the LED. It stays Red the whole time. When reading card it turns Green and after it goes back to Red.

Here are some logs from GNU Guix.

Based on the debug info do you @Gnu-Hack think that the HW reader I have is different inside? I mean it responds differently than what the library expects.

My assumption is based on the TX is the byte array that's send over USB for configuration and RX is the respond from the device.

[Gnu-Hack]

what is your reader? José CardeLL

Well it enumerates as:

$ lsusb
...
Bus 001 Device 013: ID 072f:2200 Advanced Card Systems, Ltd ACR122U

The text on the back of the NFC device says:

ACR122U
P/N: ACR122U-A9

[phodina]

@Gnu-Hack any thoughts?

I have the same problem with a new installation of Ubuntu Desktop 22.04.04

But the problem that i have found is in the libnfc6....

follow my guide for another problem...that resolve also this problem
