Thanks @ccall48, I think you forgot to add the devices to the digital-matter vendor? (the devices = [] is empty in the vendor.toml).

Maybe I should change this at my side, e.g. just remove adding devices to a vendor. There is not really an use-case I see where you would add the device toml, but not assign the device to the vendor. And then just iterate over all device toml configs instead.

Up to you boss, it wont matter if they're not class b or c compatible and the device is not?

I did those under the last commit before the update. thought i copied it all over before committing my bad 😅

This is has not really anything to do with Class-B / Class-C. It is more about the "discovery" of devices. E.g. the importer reads the vendor.toml, then takes the devices key from that config, to iterate over the .../devices/DEVICE.toml file. Instead, the importer could just iterate over the files in .../devices/. This is less error prone :)
