> You can plug a TB3 device into a TB2 laptop with a simple adapter. Apple sells theirs for $29; Chinese versions will be cheaper.

Apple's adapter has turned out not to work on Linux. It might not work with BootCamp either. Seems to require a special driver:

That's what it feels like on the bleeding edge! Again, I wouldn't suggest being the first guy on the internet to try it.

If the Apple adapter doesn't work, there are a bunch of others on Amazon, although they are a bit more expensive today. Prices will come down. But if you have a TB2 plug on your laptop, you probably have a Mac anyway.
