Review on 🔌 Cisco-Linksys USB2HUB4 USB 4-Port Hub: Enhancing Connectivity and Efficiency by Juan Simpson

This classic USB 2.0 hub is a treasure. This is a rare model that actually implements the USB 2.0 specification for power management. All hubs must either implement Per-Port Power Switching (PPPS) or disable all ports. PPPS requires a power transistor for each port, while APO requires a power transistor to power all ports. Most manufacturers cheat and skip transistors altogether by directly connecting the Vcc to 5V for all ports. This hub implements PPPS. You need something like [.] to manage port performance with this hub. You can turn USB-powered LED lights on and off or, more importantly, reset "stuck" USB devices without being physically present to unplug and reinsert the USB connector. I use this to reset Tripplite's UPS monitor USB port when it freezes.
