This is due to a bug in Crestron Home. You have to go back to the driver settings (ie. the gear), go to the Control tab. It should show the IP Address, port, username, and password. What you have to do is force the Apply button to be enabled by making and undoing a change, eg. add a 1 to the end of the username and delete the 1. Once the Apply button is enable, press it. Check the driver.
