That's tricky: - It's fairly frequent that manufacturers change the underlying hardware without changing the product name (presumably because they find that some other wifi chipset provides the same featureset at a lower cost). So you can't really trust info about "FooBar 250++ works" nor the reverse. - There's "supported" and "supported": some chipsets are well supported by the vanilla Linux kernel (tho often requiring non-Free firmware blobs), which is generally a guarantee that it will stay supported in the foreseeable future and will work reliably and without much effort (if any). Other chipsets are supported only via drivers not included in the kernel (or tentatively included in the vanilla kernel but not "yet" well integrated), and your mileage will definitely vary with those: some features may not be supported (e.g. `hostapd`), and configuring them and keeping them working in the face of upgrades can be a constant struggle. The best option is to buy one that says clearly that it works with the vanilla kernel and without requiring proprietary firmware blobs. These are hard to come by and will usually be sold by companies specializing in this market like tehnoetic.com, thinkpenguin.com, ... https://ryf.fsf.org/ can be a good starting point for that, tho it has very few products and most of them are old, but it can help find companies that care. Be aware that there is simply no wifi card (USB or otherwise) that satisfies this requirement beyond the 11n spec: beyond 11n you currently have to accept the use of a proprietary binary blob :-( Otherwise it can be worthwhile to buy secondhand, in which case the product is "fixed", so you can check which chipset it uses, and then figure out what's the status of the drivers for this chipset.
