That issue can come up when the usb device is pulling too much power from the USB as well. So it is good to make sure that you have enough power supplied to the USNB ports… i.e. if you are running the SimuCUBE on a hub or powered hub make sure that all the devices are not pulling more power than is being supplied… This is one of the reasons it is best to have the Wheel connected to a dedicated port to make sure that it receives all the Bandwidth and all the power.
