USB Over Network consists of a client install and a server install, the client install is freeware and the server install requires a license.
The client MSI is actually a nested install (or a wrapper). Start the install and then check %temp% and it extracts either 32usb-c.msi or 64usb-c.msi depending on your OS. Create a transform for this MSI if you require the below to be supressed.
Add the below properties with a value of 0 if required-
LICENSE_KEY (not required for client)
OPEN_URL (opens a URL during install and uninstall if not set to 0)
CHECK_FOR_NEW_VERSION (removes the check for new version every 15 days)
SHOW_SPLASH (removes splash screen on startup)
