Tips and Technical Support
Tips
§When connecting USB cables betweenUSB devices and the DUB-
H4, make sure that the cable is connected securely.
§Remember that when connecting USB 1.1 devices to a USB 2.0 hub
or host adapter, the USB 1.1 device will not work at USB 2.0 speeds.
§The DUB-H4 does not have an on/off switch. It is always on, once the
external power adapter has been plugged into a wall socket or power
source.
§Connecting USB 1.1 devices to the DUB-H4 may cause all USB
devices connected to the hub to work at USB 1.1 speed. To ensure
480Mbps throughput for your USB 2.0devices, don’t connect USB
1.1 and USB 2.0 devices to the hub at the same time.
§D-Link recommends that while using a USB device that includes an
AC power adapter, that you use the power adapter to ensure proper
power and current supply to that device.
§Please remember to unplug devices properly to ensure that no data
loss or corruption takes place with your operating system.
