USB automatic discovery is meant for native Home Assistant core components like the ZHA integration:

ZHA integration support ConBee/RaspBee adapters nativly without the need to use deCONZ/Phoscon:

I guess the idea is that most people who run deCONZ/Phoscon do so on a separate computer from the Home Assistant core instance and instead connect to deCONZ/Phoscon over the network via TCP/IP

Just click the “IGNORE” button for the ZHA discovery and then search for deCONZ and setup yourself.
