about pcsc-lite in hostap and wpa_supplicant

[why]

Hi, all. I have some questions about pcsc-lite.
1. My pcscd is in /usr/local/sbin/pcscd, where can i configure the wpa_supplicant to use the pcscd?
2. I use wpa_supplicant on Windows, but it asks for the sim-crad's pin again and again, how should i correct it?
Thank you very much!
