Nikon reboot needed to restart USB preview #8

Open tmandys opened 1 month ago

tmandys commented 1 month ago

When USB preview is stopped because USB cable is unplugged then USB preview won't start again and reboot is needed. Seems it is issue with Nikon 810 and 850. Typically: everything switch on, connect, focus via magnifier in camera menu requires disconnect USB cable, when reconnect then no more USB preview, reboot
