Hi
I am trying to config the Mediatec WUBM-273ACN (mt7612U) USB wifi device, install the mt7612u driver as follows:

use lsmod we can see the mt7612u module:
Module Size Used by
mt7612u_sta 1237496 1
cfg80211 589351 1 mt7612u_sta
bnep 16562 2
fuse 103841 2
…

however, the nmcli d status cannot detect the wifi device:
eth0 ethernet connected Wired connection 1
l4tbr0 bridge unmanaged –
dummy0 dummy unmanaged –
rndis0 ethernet unmanaged –
usb0 ethernet unmanaged –
lo loopback unmanaged –

use dmesg can see some errors:
