Are there any set of files that work right away with us915?
If I Install with no modifications whatsoever my gateway registers right away in region eu868.

In ChirpStack v4, the MQTT topic-prefix defines to which region the gateway connects. The default configuration has topic_prefix="eu868" (https://www.chirpstack.io/docs/chirpstack-mqtt-forwarder/configuration.html).

You need to change this to e.g. topic_prefix="us915_0" for US915.

The topic-prefix must match the topic-prefix of the region configuration, see also: https://github.com/chirpstack/chirpstack/blob/master/chirpstack/configuration/region_us915_0.toml#L47.
