compatible with USB 3 ports.

My understanding is that this particular problem is that it is a hardware
problem with some of the Intel MB chipsets (not the cpu itself). The first
thing to check however, is what else in your new computer is using the
same usb port, or the same irq. Some people have better luck removing the
USB3 driver and running the USB3 as USB2. Some have done better just
adding a PCIe USB card (in a desktop). Rumour is NEC USB chipsets work
better... but it could be just using a PCIe card on a fresh irq too.
