[Pcsclite-muscle] ACR122U NFC Card Reader

[Valentin Geffroy]

Hello,

We've noticed an issue on the ACR122U NFC Card Reader. When its is 
connected to a Linux based embedded board (using your reader with libusb 
& pscsd 2.0.1 / ccid 1.5.5), the reader is not detected by the pcscd daemon.

It works when we unplugged/plugged the reader again.

After a boot:

```

```

After unplug/plug the reader :

Do you have tips or ideas why it doesn't work at a first boot?

Thanks,
