To see which devices are connected to a driver, you can get the driver ID and, when you list the devices, search which entries have this ID on their properties.
We cannot filter the devices based on the driver used. I will create a feature request about that, I think it would be useful.
I suggest you enable the logcat in the ST CLI (command: smartthings edge:drivers:logcat) before pairing the device so you can see its fingerprint. However, there are Community drivers that show these values on the detail view of the device, like the one from @Mariano_Colmenarejo in this post.
