Power USB Hubs

Since the USB ports of your PC no longer sufficient, you have purchased a USB hub and connected (among other things) a scanner on it. However, he refuses to work – if you hang it directly to the USB connector of the PC, it works normally again. With the other devices, there are no problems. Why is that? PC World reveals it to you.

Problem:

Since the USB ports of your PC no longer sufficient, you have purchased a USB hub and connected (among other things) a scanner on it. However, he refuses to work – if you hang it directly to the USB connector of the PC, it works normally again. With the other devices, there are no problems. Why is that?

Solution:

You probably bought a powered USB hub. These hubs are supplied via the PC with power. A scanner draws but, if he does not have a power source, a relatively high current via USB. About the stroke he gets insufficient power when more devices are connected.

Therefore you either need a powered USB hub with power supply at e USB Hubs, or you miss your scanner requires a dedicated power supply. Whether your device provides for that possibility, you can see the operating instructions.
