Bluetooth devices use a specific radio frequency (2.4G) while USB 3.0 is allowed to use conflicts with the specific frequency Bluetooth devices all use, which means any USB 3.0 port, cable or device can emit radio frequencies that may cause interference with any Bluetooth devices you are using, leading to the potential degradation in performance of the Bluetooth device. This hub adopts an industry-grade chip solution rather the common consumer-grade ones prevail on the market, and during lab test it performs a much higher level of stability. Should you experience latency of your Bluetooth device, try to avoid inserting Bluetooth receiver into an adjacent port to the USB 3.0 devices. For example, you can plug your Bluetooth keyboard receiver to Port 1 (of the four ports) and plug your USB 3.0 drive to Port 4. If they still interfere with each other, you would have to plug the receiver directly to the PC.
