Description Mc James 2020-06-24 22:51:07 UTC
Hi:
I have a very complex problem.
a dongle with this chipset won't work with FreeBSD SJD 12.1-RELEASE FreeBSD 12.1-RELEASE r354233 GENERIC  amd64.
furthermore this usb dongle gets disconnected after a couple of tries of wpa_supplicant (from pkg not the base system as the wpa_supplicant from the base system would crash at the first try)

dmesg outpout is strange .... while wpa_supplicant is running ....
