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.
