Field notes
The page describes separate physical and logical diagrams: one represents the desk setup, while the other shows Windows’ controllers and hubs. Its example identifies a Corsair EX400U on a CalDigit TS4’s 10 Gbps front USB-C Data socket and recommends a rear Thunderbolt 4 port. The author says the app observes rather than changes settings, and reports measured information when Windows cannot distinguish between possible explanations.
