I have a USB2 GPS dongle and some USB3 kit (mem stick, ASI120MC) to hook up to my Stellarmate RPI4 (with RTC). It’s well documented that USB3.0 and GPS don’t work well together and I can see that happening when I plug in a USB3 device and the USB dongle stops communicating its position. Now, the ‘static’ solution would be to prevent all USB3 devices from interfering by plugging them into USB2 ports, but that of course brings the speed down. Question is: is it ok to unplug the USB dongle once kstars is started, Ekos is started and the GPS info has been synced to all devices? Thanks for your help.
