I have an Alfa AWUS036ACM (Mediatek MT7612U).
My AP keeps dieing.
The error:
mt76x2u: error: mt76x02u_mcu_wait_resp failed with -110
seems to be common.
I use it with a build of a OpenWrt on a Raspberry Pi 4 (Broadcom BCM2711
SoC, ARM Cortex-A72 processor (64bit)).

I bought a powered USB3 hub and removed a USB3 cable in case that is
related but the problem is still there.
I've been documenting my problems:
https://github.com/openwrt/mt76/issues/405#
Are any of the tracebacks useful?

@petrkalosthis conditions is used to reset the device in case of
necessary (it is in the vendor sdk). You can try to comment it out and
see what happen
I downloaded
https://d86o2zu8ugzlg.cloudfront.net/mediatek-craft/drivers/MT7612U_DPO_LinuxSTA_3.0.0.1_20140718.tar.bz2
and there is no "mcu_wait_resp".
I also found this:

What 80211.ac USB adapter has the best (most open and compatible) now
(or likely) linux kernel support?
