Hey @bfleming and welcome to the Community.
You can check out the Compatibility Page if that's not the page you looked at already.
If it's not listed, that would mean it's not tested or compatible. I wouldn't recommend using an untested device with any of our hardware since we can't guarantee it'll work.
