Well, apparently either this was an uninteresting or much too hard question... 
So to simplify it a bit:
How and where can I as a normal (and non Linux) user know what USB Wi-Fi adapters are supported by LE??
As there is (AFAIK) no way of using vendor drives without building/compiling/.../... I think this is quite valid question.
I dont think there are any good choices, almost all usb wifi is based on realtek chipset which is trouble.
Could anyone share ideas about a good (stable with acceptable speed) USB Wi-Fi adapter for LE use.
I'm adding a LE player in a location where Ethernet is not an option.
My $0.02 is to invest in an Ethernet/Wireless bridge device. I use them with whatever test device I happen to be looking at .. to avoid the hassles of configuring WiFi connections. As "router" devices they have a larger antenna built-in which contributes to more stable connections (although stable is not a word I ever associate with WiFi) and since they present Ethernet to the test device there are zero driver issues. I used to collect/use old Apple a1rport devices as they are simple and cheap, but these days they're getting a bit old.

TY, that might be a (at least temporary) solution!
I have an unused "Comfast CF-WR754AC" lying around... Specs says it's a 1200Mbps (-ish) unit so should be suitable here.
It's a three mode Repeater/Access Point/Router so in AP mode it should/could do the trick!
Again, TY!!
