Adjustable angle: The main USB plug can rotate 180 degrees, which helps position the hub to fit into tight spaces or avoid blocking other ports. Interface: It features an input interface for USB 2.0 and an output of eight USB 2.0 ports. Data transfer: The hub offers data transfer rates up to 480 Mbps, consistent with the USB 2.0 specification. Plug-and-play: This device is driverless, meaning it can be used immediately after plugging it in, without needing to install additional software. Compatibility: Supports various operating systems, including Windows XP, Vista, 7, 8, 8.1, and Mac OS.
