That's not true. It varies device by device. Some new devices have
excellent drivers. Always check http://linuxwireless.org/.

Gavin,
Many drivers have debug mode, which will output to the kernel logger
(`journalctl -k` or `dmesg`). It varies by driver, and you'll have to
poke around in /sys to find it, and probably write 1 to a file.
Additionally, putting wpa supplicant in debug mode `-dd` option to
`/usr/lib/systemd/system/wpa_supplicant.service` might get you more
information.
Well, yes and no. Sure, if you know what chipset you are looking at, etc. you can look it up. But...
1) That list isn't 100%. I have bought a few adapters after looking them up that were supposed to work and didn't.
2) I'm one of those guys that tends to collect computer detritus. I'm the guy who "just happens" to have the HDMI to micro-HDMI adapter in his backpack when someone can't hook up their laptop for a PowerPoint presentation. Just because. Oh, you want a parallel printer cable? A Zip drive? I just happen to have one here somewhere...
Folk like me seem to come in two flavors, I've observed. It's like buying power lawnmowers. I have friends who buy these $1000 push lawnmowers and say "It's worth it! These things will last 30 years if you take care of them," and they carefully do all the maintenance things you are supposed to do -- only use ethanol-free gas, keep them sparkly clean, sharpen the blades so you could shave by sticking your face in the rotors, etc. Then there's folk like me, who go to Walmart and buy the cheapest damn piece of shit that works for $100 bucks. Then I use it until it fails (usually 1-2 years) and then go out and buy another.
Which way is better? It depends on how good $100 lawnmowers are in 2045. Because I'll be in Walmart buying a new one, and my friend won't.
Same thing is true with computers. Some folk go out and buy the $5000 laptops because, you know, they are the best and you can keep them for 10 years (I actually fell for that in the late 1970s when a selling point for the first 8-bit personal computers was that the motherboards used gold solder so the computer would last 20 years. I paid an extra so I could get an Exidy Sorcerer, I think it was, with a custom motherboard.) I stopped doing that in 1980. Other folk (like me) make a point of buying last year's laptops for $500 (and preferably a demo from Staples for $300), and get a new one every year.
And the same thing's true for these kinds of accessories. There are these guys and gals who go out and buy the $300 usb wifi adapters and the $200 cables and stuff because, you know, that's the "good stuff." And there's people like me who go on Ebay and buy 10 cheap things that are borderline disposable with the idea that if one of them works, you're ahead.
And when you do it the second way, you don't always know what chipset you are getting. God only knows what they shove in those little toys they make with child slave labor in those sweatshops in Guangzhow and sell for $1.99 with free shipping. However, you do know that if they were selling the same thing last year, it's probably old enough so that the current linux drivers support it. And if you buy 5 different kinds, at least two will work.
