There are times when you will run across an “Unknown Device” error when using the Hardware Utility. The most common cause of this is using software that was published before the device you are using was released.
For example, when the first “S3” boards were released people using the “S2” version of software would get this error. Why? It boils down to a text file that doesn’t have the correct information in it. Your device will work, though you might not be able to update firmware in the future.
If you have the ability to move to a newer version of the software, it would be recommended.
The other work-around is to contact the Light-O-Rama Help Desk, and ask them to send you a file that will resolve this “Unknown Device” error.
