• Mac OS X Lion 10.7.4 users should upgrade to Mountain Lion 10.8.2 or later to avoid unstable connections. 

Power Usage Alerts

• For stable operation, devices connected to this hub should not exceed a combined current of 5V 900mAh. 
• It is not recommended to use this USB hub for too many peripheral devices with high energy consumption. Two external 2.5 "hard drives without any additional power supply to bring the USB port of the PC is already at its limit. 
• This hub is not meant to serve as a stand-alone charger. It is not compatible with iPads or any other devices with irregular charging requirements. 
• 2.4Ghz wireless devices, such as wireless keyboard and mouse adapters, may not work in close proximity to USB 3.0 devices or hubs. Connecting to a USB 2.0 port is recommended.
Make every effort to solve your doubt
+ Why is my computer unable to shut down when the hub is connected?

1. Please unplug the hub and see if your computer is then able to shut down.

2. Please unplug the AC adapter from the hub and see if the PC will shut down properly with the hub plugged in. If this solves the problem then the issue is with the hub. Please feel free to contact our support team for an exchange or refund. If it does not help, Please attempt the further troubleshooting below:

a. For Windows users: Adjust your power settings as follows: Right-click “My Computer”, select “Attributes”, then “Hardware”, followed by “Device Manager”, double-click “Universal Serial Bus Controllers”, right-click “USB Root Hub”, click “Attributes”, then “Power Management”, unmark “Allow computer to close the device to save power”, click “Yes ”, and then restart the computer.

For Mac users, please uncheck the box "put the hard disks to sleep when possible" in energy saver.

b. Check the USB 3.0 host and update its driver to the latest.

c. Try a different USB 3.0 cable/usb port.

If the further troubleshooting doesn't help then contact our support team.

+ Do you have any driver for the hub?

Our cateck Hubs are plug-and-play so there's no need for extra drivers, but we do recommend updating your USB controller’s drivers and firmware to the latest version. This ensures a smooth experience using any USB devices. To do this you should identify the brand of your USB controller then search online, or contact your PC/motherboard supplier directly.

+ Why do my wireless mouse/keyboard not work closely with Cateck USB 3.0 hub?

2.4Ghz wireless devices may have frequency interference issues with USB 3.0 ports so we recommend using a USB 2.0 hub instead.

+ My Western Digital hard drive cannot be recognized by your hub? How to fix it?

This could be to do with the firmware on your Western Digital hard drive. Try installing new firmware, downloadable from the Western Digital website.

+ Will the current requirement of my devices influence Cateck hub's performance?

For maximum performance, connected devices should not exceed the combined current of the output of hub. Otherwise, output current may become unstable or disconnect entirely. See some commonly used devices' general requirements below:
250G Hard drive – 600mA
4G Flash drive – 100mA
64G SSD – 400mA
100M Network adapter – 500mA
Keyboards and mice and other peripheral devices – 100mA (or less)

The ratings above are estimates only. Please check your specific device's ratings before connecting to the hub.

+ Why is the WIFI on my Mac affected by the hub?

USB 3.0 connectors and cables can radiate interference in the 2.4 GHz spectrum that causes Wi-Fi and Bluetooth signals to intermittently drop out when they're near the antennas. You can refer to the link below for further reference: 

For the MacBook Pro and MacBook Air, those antennas happen to be near the screen hinges along the back of the computer. Moving the hub away from this area could help to improve your WiFi signal.
