ACR128U is based on NXP RC531 reader chip which doesn't have anything in common with the PN53x family currently supported by libnfc.
So adding (partial, no NFC, no card emulation) support for this reader is not straightforward.
Contributions are welcome.

How can ACR128 support can be added to "acr122_pcsc" driver...
pcscd releases context after received CMD_GET_READERS_STATE command from libnfc enabled client.
Can you point me to the right direction...

Any idea why nfc-list detects no device?

Yes, of course : ACR128U is not supported by libnfc.

BTW, it may be more easy than it seems : try to add it at libnfc/acr122.c supported models and see what happend.
