[Multitech] Help with packet-forwarder-usb

Please, help!
For several days/nights I have been checking and making changes to the configuration of the package lora-packet-forwarder_usb without getting any progress, my problem is that I can not boot the packer-forwarder and therefore there is no communication with the gateway-bridge, I followed the configuration guidelines.

Next I enclose my global_conf.json in case they detect any error that makes the output that I show later happen.
