I was able to use the USB 3.0 port to connect to the Q10 Pro and use it same as any external drive. After installing an internal drive, copying large Blu-ray files was easy using Window 10. I am "old school" and reformatted the 4Tb drive the old slow way (which took a very long time) so there were no disconnections for many hours.
Were you connecting to an internal drive or an sd card?
Try connecting to a USB 2.0 port on your notebook if you have one (some older PC USB 3.0 ports and drivers can be flaky and USB 2.0 are stable)?
Also I find a full reboot of Windows can get USB drivers working correctly after Windows updates messes around with things.
