When I open the Windows Device Manager, the device list repeatedly refreshes
This is a known issue if you are using the X50-MS2, you are powering the local unit from USB and have no USB devices attached to the remote unit. The solution is to either power the X50-MS2 unit from an external power supply (PSU-IEC-5VDC-2.5A) and remove the USB cable or connect a USB device to the remote unit.
