Operation

1.  Connect the cable’s mini-B-plug with the corresponding port of your hub. Connect the  

USB A-type plug to a vacant USB port of your PC. The hub is now operational.

2.  If required, switch each of the four ports on or off individually using the corresponding 

toggle switches positioned on the hub top (I = On, O = Off).

 

The hub functions in “Bus-Powered-Mode”. This means that the current of 500 mA 

supplied by the computer via USB is divided among the 4 ports. The total current 

consumption of all devices connected at any one time must not be higher than this 

value.

3.  Alternatively, you can power the USB hub with an optional power supply. If an optional 

power supply is used, then each port could be loaded with 500 mA. 

 

You can connect up to four USB devices to the hub. The hub supports Plug & Play 

and hot-swapping (device drivers are automatically recognized and the devices 

themselves can be removed while the OS is running).

Tips & notes

•  The USB 2.0 is USB 1.1-compatible. That means that traditional USB 1.1 devices can be 

operated without problems on the USB 2.0 hub. USB 1.1 devices do not become quicker 

through this! The USB 2.0 hub can, of course, also be operated on a USB 1.1 connection, 

e.g. if your PC has no USB 2.0 connection. An increase in speed in the data transmission is 

not possible here either. To be able to exploit the high speed (theoretically 480 MBit/s, i.e.  

60 MByte/s), all devices must support USB 2.0 - the USB device (e.g. an external CD burner) 

itself, the USB hub and the USB controller in the PC. In practical operation, the 480 MBit/s 

are not achieved. Hardly any device (e.g. hard disk, burner etc.) is in a position to supply data 

so quickly. Other causes also (e.g. simultaneous operation of other USB devices, protocol 

information etc.) reduce the transmission rate.

•  USB operation is not possible in Windows safe mode or under DOS. USB keyboards and 

a USB mouse do not normally work. The BIOS/setup of your PC possibly has appropriate 

support (could be called e.g. “Legacy USB support”). It is possible, however, that the USB 

keyboard/mouse is to be connected directly to the motherboard and not on a USB hub.

Care and cleaning

•  Disconnect the product from the power supply before cleaning.
•  Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as 

they can cause damage to the housing and malfunctioning.

• 

Clean the product with a dry, fiber-free cloth.

•  Do not immerse the product in water.

Disposal

  Electronic devices are recyclable waste and must not be disposed of in the 

household waste. At the end of its service life, dispose of the product according to 

the relevant statutory regulations.

 Operating instructions

4-Port Switchable USB 2.0 Hub

Item no. 1628893

Intended use

This product serves to connect up to four additional USB devices. It has been designed to be 

connected to a computer with USB interfaces. During operation it operates like a bi-directional 

repeater, which repeats USB signals as required on upstream (computer) and downstream 

(peripherals) cables. It is designed for USB 2.0 and backward compatible with USB 1.1. Its 

operation requires connection with a computer.
It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in 

bathrooms, must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use 

the product for purposes other than those described above, the product may be damaged. 

In  addition,  improper  use  can  cause  hazards  such  as  short  circuiting,  fire  etc.  Read  the
