What is the problem?
What result did you expect?

[zelix25]

My reader is connected to gpio 14 and 15 (uart_tx and uart_rx) and visible with nfc-scan-device.
The problem is that I have no detection when I use pcsc_scan.

pcsc is compatible with uart_tx and uart_rx ports?

[LudovicRousseau]

You have 2 pcscd installed on your system: version 1.9.9 and version 2.0.1.
Remove the version installed in /usr/local/ and try again.

I went with a new installation and reinstalled the pcsd package. This is version 1.9.9. But it's always the same.

It looks like you have not installed ifdnfc https://github.com/nfc-tools/ifdnfc

[zelix25]

I forgot to install ifdnfc....

Thank you very mush :)
