For implementation within SKYRS workstations and remote sites, follow these standard operating procedures:
Connect the USB 2.0 male connector to any available USB port on the host machine. For desktop users, the 1-meter cable allows the hub to be positioned on the desk surface even if the PC tower is located on the floor.
While the hub is Plug & Play and bus-powered, certain deployments require additional stability:
Passive Mode: Ideal for mice, keyboards, and flash drives.
Active Mode: For “power-hungry” peripherals (like external 2.5″ HDDs or PC fans), connect a standard Micro USB cable to the side power port. This ensures the 500mA limit of a single USB 2.0 port does not cause device disconnection.
The UGREEN 20277 requires no manual drivers. It is instantly recognized by:
Windows: XP through Windows 11.
macOS: All versions (Plug & Play).
Linux: Kernel 2.6 and above.
Android: Compatible via OTG (requires a separate OTG adapter).

Technical Advice for SKYRS Staff: Although this hub features 4 ports, the total bandwidth of 480 Mbps is shared across all connected devices. For high-speed data migration tasks, it is recommended to use the UGREEN 3.0 series available in the SKYRS catalog.
