This USB Hub adds three USB-A 3.2 Gen 1 (5Gbps) ports and one Gigabit Ethernet port to a USB-A enabled desktop or laptop computer. The USB Hub connects to a USB-A port on a computer, using the built-in 1ft. (30cm) host cable. The USB hub is backward compatible with USB 2.0 (480Mbps) devices, ensuring support for a wide range of modern and legacy USB peripherals (e.g., thumb drives, external HDDs/SSDs, HD cameras, mice, keyboards, webcams, and audio headsets).The USB hub is compact in size, facilitating portability when travelling. The USB hub features a Gigabit Ethernet adapter. The Ethernet controller is compatible with the IEEE 802.3u/ab standards and supports Wake-on-LAN (WoL), Jumbo Frames, and V-LAN Tagging. The network adapter enhances laptop network reliability, security, and performance, by utilizing wired 10/100/1000Mbps Ethernet. The USB hub can operate with bus power alone, but features a Micro USB power input that can be connected to a USB power adapter (not included), providing up to 4.5W (5V/0.9A) of power in addition to the 4.5W of bus power from the USB host. This flexibility is ideal for applications where additional power may be required, such as connecting a high-powered USB device, like an external SSD, while using the other ports to connect lower powered devices. The downstream ports are each capable of providing up to 4.5W of power to the connected peripherals. For added protection to this USB hub and the connected host device, the USB hub features Overcurrent Protection (OCP). OCP prevents faulty USB peripherals from drawing more power than is safely allocated. This device is OS independent, supporting all operating systems, including Windows, macOS, ChromeOS, and Android. The Hub is automatically detected, configured, and installed upon connection to a host computer, such as Apple MacBook, Lenovo X1 Carbon, and Dell XPS. The extra long built-in 1ft. (30 cm) USB-A host cable enables quick and convenient setup and reduces connector strain on 2-in-1 devices, such as the Surface Pro 7 and laptops on riser stands. Improve performance and security with Connectivity Tools. The software suite includes: the MAC Address Pass-Through Utility, the USB Event Monitoring Utility, and the Wi-Fi Auto Switch Utility.
