ACR122U USB Port problem

Hello I hope for your understanding as freshman.
Windows 7
equipment ACR122U
My problem no COM port in Device Manager
  I have the ACR122U when I plug in the device I get no com port output but only a smart card reader has been successfully installed as I can tell, the PM3 Gui I have only PCI port

Hallo ich hoffe um verständnis als neuling.

Mein Problem keine Com Port in Geräte Manager
Ich habe das ACR122U wenn ich das gerät anschliesse bekomme ich keine Com Port ausgabe sondern nur das ein Smartcard Reader Erfolgreich installiert wurde wie kann ich das PM3 Gui sagen das ich nur PCI Port habe.

Re: ACR122U USB Port problem

I don't know if you expressed your problem a bit sloppy, or if you're just confused. The "PM3 Gui" is a gui for the proxmark3-device, it's not a piece of software you can use with an acr122u device. Check out libnfc and/or rfidiot instead.

Re: ACR122U USB Port problem

I'm getting mad I use Kali Linux 2.0 hardware ACR122U
I like to change the UID Want but it's not possible.
here's the issue
root @ kali: ~ # NFC mfsetuid a1b2c3d4
NFC reader: ACS / ACR122U PICC Interface opened

to what it could be the reason the Mifare card 1K UID can not be subject to change

Re: ACR122U USB Port problem

I think I can only reply what @Holiman did in the last reply.   

This is a Proxmark3 forum and if you need help or have some questions about ACR122U/libnfc  it would be better to ask in their dedicated forum instead.
