Issue with ACR-122U #94

Closed mzeitler closed 4 years ago

mzeitler commented 4 years ago

I have a strange issue with the ACR-122U reader on Raspbian Buster.

Even though the device is recognized with lsusb, I get infrequent errors. It works until an error appears. Once an error appears I need to unplug the USB and plug it back in to get t working again. In most cases this solves it. Or I have to replug again. Rebooting doesnt solve the issue though.

I have blacklisted pn533 as this was recommended elsewhere /etc/modprobe.d/blacklist-libnfc.conf blacklist pn533_usb blacklist nfc

lsusb Bus 001 Device 006: ID 072f:2200 Advanced Card Systems, Ltd ACR122U

How can I get rid of this error make to make the reading of tokens more reliable?

This is NOT an issue with pyscard.

I don't know what driver you are using. Maybe https://github.com/acshk/acsccid would fix your problem.
