Working on a project like that with a Pi Zero can be difficult. Do you have a bigger Pi, a Pi 4 or 5? A Linux PC? You could then perform diagnostics faster and with more choices.
Some of the plug in adaptors I tested on my Pi Zero 2 would work only through a powered USB 3 hub. Some adaptors failed with some USB cables but worked with better quality USB cables.
OpenWRT had problems when I tried to use it. Some things that worked in the Pi OS did not work in OpenWRT because the drivers were different. You would get better support here if you tested the same devices with Pi OS.

Is this an official Raspberry Pi power supply? They produce 5.1 volts to offset voltage drops in the cable and the Pi circuit board. Other power supplies start with only 5 volts and that can cause big voltage drops when using USB devices requiring significant current.The Raspberry Pi's power supply is 3000 mA.
