I have installed OpenWRT 19.07 on a VM on ESXI Arm Fling on a RPi with the VM found on this topic. Arm fling installation
This works great but I have one problem. I can't install the kmod-rt2x00-usb package. When installing, I get this error.
Chances for passing through a USB WLAN card to a VM are minimal to begin with, as USB can't be passed through (like PCIe could be) but needs to be partially emulated and WLAN drivers generally being very timing sensitive (rt2800usb isn't going to be great to work with in AP mode either).
Apart from that, keep in mind that 19.06.x is EOL, upgrade to 22.03.x first (not that I expect that to work much better, but at least it has security support) - I wouldn't be surprised either if ESXI/ ARM wouldn't provide USB support or other exotic-on-ARM use cases.
