I have had usb3.0 problems with my NanoPC-T4, close relative of your NanoPi-M4 but not really the same.
When using my ZWO ASI294MC pro camera (USB3.0) the first image in any sequence is saved, but then the software goes into a cycle where the countdown continues for the next image, reaches zero but the image is not saved, this continues over and over. To reset, I need to shutdown the software and re-boot the NanoPC-T4. The camera works fine when plugged into one of the NanoPC-T4 usb2.0 ports, it just saves images at the usb2.0 speed. That isn't a big problem for me as I just do DSO im
