USB 2.0 External 4 Port Hub

Who wants to infect multiple devices to the PC via a USB port, often faces the problem that there are not enough USB ports available. Here help USB Headers (USB hub) as a distributor. The tested USB hub provide mostly good data transfer speed. Unfortunately, some bars were but with some significant security flaws.

First, the mouse and keyboard, followed by the printer and finally an external hard drive, a USB flash drive or MP3 player. Over time, as is more and more hardware via a USB connection to the computer. And before you know it, all existing USB ports are being used.

Especially with notebooks or older PCs with just two or four terminals it is then quickly close. USB Headers – also called USB hubs – remedy. These multiple sockets for USB hardware are inexpensive to purchase and provide for sufficient space for at least 4 or even more USB ports (see eusbhubs).

USB hub with its own power supply are usually beneficial

To differentiate it is between active and passive devices. Active USB hub does not have its own power supply, passive Headers hand. This can be a disadvantage. For all the devices connected to the USB hub must share the power of a USB port on the PC. Power hungry hardware such as external hard drives or USB TV sticks can be so usually do not operate simultaneously.

The magazine Computer Bild has therefore taken in a test only 18 active USB hub closer look. In the test, there was between the devices in positions one to twelve little difference: all were at a “very good” data transfer speed points. Test-winner was the Belkin USB 2.0 7-Port 2-in-1 Hub.

It offers good facilities and handling for a period of 30 years and cut thus the test result with a total of “good”. Just as the price-performance winner of DeLock (USB 2.0 external 4 port hub). That was around 13.49 euros, the cheapest USB hubs in the test.

Risk of electric shock at USB distributors

However, it was during the test clearly that but serious safety deficiencies in power supply exist in some devices, which led to significant devaluations that. Right next to two USB distributors came in high voltage test to dangerous sparks, already in normal use thus pose a shock hazard. The logical consequence: test result “unsatisfactory”.

Another two test candidates passed the high voltage test, under certain circumstances, the user is still at risk. Five models did not comply with EU rules and were thus at the EMC test (electromagnetic compatibility).
