Question: 

I am using the official Axys USB to RS-485 adapter but cannot connect to my Intellivox speakers after upgrading to windows 10.  Where can I find an appropriate driver? 

Answer: 

Normally windows should automatically download the correct driver for the adapter but sometimes this does not happen correctly.
