Do you have a USB2 port free? try that. Or if you have connect any USB hub to the USB3 port and then use the modi. This seems to be an issue with (some) DACs for quite some time. Even with the HDP via USB I had this issue, my Modi is connected via a powered USB3 hub and everything is fine (but on a Mac).
