[cswhiting63]

I have 3.2.1 software had my firmware updated and was connecting then I updated to 11.1 OS "Big Sur" and I cant connect i reinstalled driver restarted nothing but demo mode BEC is on just red and blue on interface and the Blue LED is on Spirit 2 unit any ideas what else to try I have windows 10 on mac will try that but any ideas on MAC? I was able to get the WINDOWS with parallels 16 to connect so must be a OS 11.1 driver issue I like the Mac better let me know if you find a solution I just tried again and it wont see the device in Sur thx

You have to download new USB driver from Silabs web page.
Version 6 is compatible with Big Sur and is only few days old.
