Topic: ACR122U-A9: Error 0000001f

Hello,
my first post here, thank you for your patiente. I'm windows user.

I bought a ACR122U-A9, install official driver for device.

When I try to read a card receive an error :
error   libnfc.driver.acr122_pcsc       No ACR122 firmware received, Error: 0000001f

Digging around he found a possible incompatibility between the reader and the library   libnfc.dll   :
hxxps://superuser.com/questions/1477349/acr122-nfc-reader-does-not-work-with-libnfc-ubuntu

User of this forum suggest to remove some lines from "acr122_usb.c"
hxxps://github.com/jpwidera/libnfc/commit/a77a2a84971f4c588a6377b30975bbe3b15d5ab4

But for me it would mean recompiling the entire library. I don't think I'm capable.

Could this actually be the problem?

Thank you for your time,
m.
