Have the Logilink 10 Port USB 2.0 Hub appointed in late February and today my computer would not turn back. After I have the USB Hub disconnected from the computer, everything works again without problems. Have now again 2x 4 Port USB Hubs and everything works on the computer. I put again the Logilink 10 port USB hub in, my computer will not boot. So clearly the USB hub or the power supply break. Will it now return. Let's see what the manufacturer says.
