Step 1 - Download the ZIP file for the specific version of your ESXi host and upload to ESXi host using SCP or Datastore Browser

Step 2 - Place the ESXi host into Maintenance Mode using the vSphere UI or CLI (e.g. esxcli system maintenanceMode set -e true)

Step 3 - Install the Offline Bundle by running the following command on ESXi Shell:

esxcli software vib install -d /path/to/the offline bundle

Step 4 - Plug-in the USB NIC and reboot for the change to go into effect. Once the host has rebooted, ESXi should automatically pickup and claim the USB NIC (e.g. vusb0)
