If you read the edge FAQ that I previously gave you the link to, it tells you how and where to find drivers. Right now, there are four sources.
-
stock drivers automatically updated to your hub. This will happen automatically, little by little, with no advance notice.
-
stock drivers currently available in the smartthings beta channel. This gives you early access to the stock drivers that will later be distributed automatically, but they may have glitches. Also note that sometimes fingerprints are listed there but they are commented out because they aren’t ready for release yet.

- the table of edge drivers in the community - created wiki. Lets you look for drivers by model. It’s a good table and includes both stock drivers and custom drivers, but it’s very new and definitely incomplete. So if you don’t see your model there. It doesn’t mean there isn’t a custom edge driver for it, it just means the table hasn’t been updated yet.

- The quick browse lists in the community – created wiki are more up-to-date, but are just by device class. So there’s one list for locks, one list for sensors, etc. then you have to look through the matching topics to see which might match your device. So it’s more work than a table, but more complete.

And again, if you read the community FAQ on edge, it has all of this information and more.
