4. Setup Instructions
- Connect Computers: Use the two included USB 3.0 A-to-A cables to connect the two USB Input ports on the switch to available USB 3.0 ports on your two computers (Host 1 and Host 2).
- Connect Peripherals: Plug your USB peripherals (e.g., mouse, keyboard, printer, scanner, USB flash drive) into the four USB Output ports on the switch.
- Optional Power Connection: If you are connecting high-power USB devices such as external hard drives or digital cameras, connect a standard 5V power adapter (not included) to the Micro USB 5V Power Supply Interface on the switch. This ensures stable operation for all connected devices. Low-power devices like keyboards and mice typically do not require external power.

5. Operating Instructions
Once the switch is set up, operating it is straightforward:
- Switching Computers: To switch control of the connected USB peripherals between your two computers, simply press the 'Switch' button located on the top of the device.
- LED Indicator: The LED indicator light on the switch will change to show which computer (Host 1 or Host 2) is currently active and has control over the shared USB devices.
6. Troubleshooting
- Device Not Recognized or Unstable Connection:
- Ensure all USB cables are securely connected to both the switch and your computers/peripherals.
- For high-power devices, connect an external 5V power adapter (not included) to the Micro USB port on the switch.
- Try connecting the peripheral directly to the computer to rule out device-specific issues.
- Ensure your computer's USB ports are functioning correctly.
- Slow Data Transfer:
- Verify that you are using USB 3.0 compatible cables and ports on both the switch and your computers for optimal speeds.
- Ensure no other high-bandwidth devices are simultaneously using the same USB controller on your computer.
- Switching Delay:
- A slight delay (typically 2-3 seconds) may occur when switching between computers as the system recognizes the peripherals. This is normal operation.
