For USB 3.0 transfer speed, your computer must have a properly working USB 3.0 port to plug the USB 3.0 hub. The USB device must also be a USB 3.0 interface device and using USB 3.0 cable (if needed). This USB 3.0 hub is a bus-powered hub that draws power from the computer’s USB port at a maximum total current of 900mA. Bus-powered USB devices that draws power alone from the USB port of the hub maybe low-power (≤150mA) or high-power devices (≤900mA). When plugging a high-power device like bus-powered external hard drive, you may need to unplug other USB devices from the USB hub first. 2.4GHz wireless devices, such as keyboard and mouse, may not work in USB 3.0 ports or near USB 3.0 devices due to noise interference. This is a known issue for all USB 3.0 hubs. Try connecting to the computer’s USB 2.0 port instead (or use USB 2.0 extension cable). This USB 3.0 hub is not a stand-alone charger.
