ACR122 NFC reader does not work with libnfc ubuntu

I just got myself a new ACR122U-A9 nfc reader that I need to set up with libnfc on ubuntu 18.10. It needs to work with libnfc because mfoc interfaces wit that (If there is a way to use mfoc without libnf, great! That solution would help me as well!) After installing libnfc 1.7.1 and doing a few hours of research I still did not get it to work. Every time I use sudo nfc-list and pcscd is not running it gives me the following error:

nfc-list uses libnfc 1.7.1
error   libnfc.driver.acr122_usb    Unable to set alternate setting on USB interface (Connection timed out)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:004:005

If pcscd isrunning, the error reads as follows:

nfc-list uses libnfc 1.7.1
error   libnfc.driver.acr122_usb    Unable to set alternate setting on USB interface (Connection timed out)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:004:007
nfc-list: ERROR: Unable to open NFC device: acr122_pcsc:ACS ACR122U 00 00

And sometimes this shows up as well:

nfc-list uses libnfc 1.7.1
error   libnfc.driver.acr122_usb    Unable to set alternate setting on USB interface (Connection timed out)
nfc-list: ERROR: Unable to open NFC device: acr122_usb:004:007
error   libnfc.driver.acr122_pcsc   No ACR122 firmware received, Error: 80100016
nfc-list: ERROR: Unable to open NFC device: acr122_pcsc:ACS ACR122U 00 00

What I read from that is:

I already did the following things:

Can anyone help me out and/or tell me what I did wrong? Thank you in advance!

PS: I somehow got it to work with pcscd, but since I couldn't figure out how to make mfoc use that (if that's even possible) it's no use.

Nowadays you can install from sources version 1.8.0. This version have this problem resolved.

First uninstall libnfc-bin

download sources of version 1.8.0 And that is what I have done:

export CFLAGS="-Wall -g -O2 -Wextra -pipe -funsigned-char -fstrict-aliasing \
      -Wchar-subscripts -Wundef -Wshadow -Wcast-align -Wwrite-strings -Wunused \
      -Wuninitialized -Wpointer-arith -Wredundant-decls -Winline -Wformat \
      -Wformat-security -Wswitch-enum -Winit-self -Wmissing-include-dirs \
      -Wmissing-prototypes -Wstrict-prototypes -Wold-style-definition \
      -Wbad-function-cast -Wnested-externs -Wmissing-declarations"

autoreconf -Wall -vis
./configure --prefix=/usr --sysconfdir=/etc
sudo make clean
sudo make
sudo make install

After that I have tried nfc-list and it works

nfc-list uses libnfc 1.8.0
NFC device: ACS / ACR122U PICC Interface opened
