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.
Notes
To achieve the maximum output current of 10A at 900 mA, the must be powered by both
the external power adapter and the computer turned on.
To ensure a stable connection, the connected devices must not exceed a combined current
of 10A. This is especially important for any devices with high power requirements such as
‘self-powered’ hard drives which draw power from the USB port. Estimated power usge
rating of some common devices for your ready reference – Portable hard disk (max 0.5A),
USB 3.0 portable hard disk (max 0.9A), keyboard (max 0.5A), mouse (0.1A), camera (min
0.3A). 1A = 1000mA.
Microsoft Windows systems should install latest manufacturer USB 3.0 host controller
drivers and Windows Updates for best results. Apple Mac OS X and Linux / Unix systems
require latest operating system updates for best compatibility.
The 10
th
port is BC 1.2 (Battery Charging) compliant. It delivers fast charge (up to 1.5A),
while simultaneously transferring data, to USB enabled devices when the computer is in
sleep mode or shut off. Other 9 USB ports are data-specialist ports, offer only 0.9A current,
may not supply enough power to iPhones, iPads or any other smart phones.
Some devices such as the Apple SuperDrive look for Apple-specific signaling and will not
work when connected through any USB hub.
We do not recommended this hub for use with USB 3.0 PCI-e add-on cards for older Apple
Mac Pro systems because of limitations in their software support for USB 3.0 hubs.
2.4Ghz wireless devices such as wireless keyboard/mouse receivers, Bluetooth and WiFi
adapters may have frequency interference issues with USB 3.0 ports, may not work in close
proximity to USB 3.0 devices or hubs. Connecting wireless devices to a USB 2.0 port is
recommended.
Special Note: Logitech devices may not be compatible with this hub. We found some Logitech devices
not compatible with any USB 3.0 hubs.
