Beginning with Transport firmware v18.104.22.168, the Device Discovery (ADDP) Service, which is required for the Device Discovery Utility to work, is disabled by default for security reasons.NOTE
: If upgrading to v22.214.171.124 or later from a previous version of firmware, ADDP will not be automatically disabled. This only applies to new units with firmware v126.96.36.199 or later, or TransPorts that have been recently re-flashed using FlashWriter with a firmware version v188.8.131.52 or later.
In order to Discover a TransPort with the Device Discovery Utility, ensure at minimum that the ADDP service is Enabled. If this doesn't help, please refer to KB article Device Discovery Troubleshooting Tips
