A bit more info on this...
I've been messing around with my X99 board which has 3 USB 3.X controllers on it (Intel USB 3.0, VIA USB 3.0 and Asmedia USB 3.1).
The issue occurs on this board no matter what controller the device is connected to be it the intel, via or asmedia ports.
Simply uninstalling the intel XHCI driver (the latest version released on Jan 29 2016) resolves the issue on all USB ports. Re-installing the intel XHCI driver and the issue re-appears even with the other controllers USB driver/monitor installed.
As the issue happens also with an Intel made board from an older chipset which uses a much older driver I do not know if the problem is with the logitech driver or the intel driver. Thanks
