What to do if wpa supplicant failed to initialize driver?
USB is the internet from my Android device. Please make sure you run wpa_supplicant as root (I’m against using sudo) and kill any existing instances of wpa_supplicant before you start your manual test. NetworkManager (never used it) might interfere and indeed, try to get rid of it for the moment, until you’re sure your conf files are OK.
Why is my WPA interface in Unkown state?
The interface is not UP, is in UNKOWN state. Have you brought it UP? Which Wireless Adapter is it? Also, before running wpa_supplicant, you need to generate the wpa_passphrase like this: have you done that? EDIT: I should have RTFM, leave aside both my interface status and wpa_passphrase suggestions: they’re misleading, sorry for that.
Why does subsequent calls to wpa _ supplicant fail?
However, subsequent calls to wpa_supplicant (for the other profiles or even the same one) yield a more verbose output: wpa_supplicant still returns an exit code of zero, but the wireless device is most definitely not connected to any network this time. Any advice or thoughts would be greatly appreciated, I don’t know how to debug this or fix it.
Why is my wlp2s0 link not connected?

Why is wpa _ supplicant not working in Windows 10?
It couldn’t work because you needed to start wpa_supplicant anyway (or iw if connecting without encryption) to establish a “layer 2” connection to your gateway, and then manually set up your ip address and the default route (without dhcp, ensuring the subnet is correct and the ip address is not being used by any other machine in your network).
