I have not been able to repeat the problem. I have checked my udev rules, ran udevadm to check on device settings, unconnected and reconnected the tablet via usb tethering, set both automatic and manual ip definition of the usb wired connection (Note: I am running 64 bit Ubunto LTS 20.14 - and not making any updates as everything was working - same for the version of Kstars). What ever I do now seems to work. Nothing has changed the CGEM XML file in .indi directory. Yet, I know yesterday when I checked that file (as a last resort as to why the mount would not connect even though the error was telling me it had something to do with USB0 and USB1) it had the connection set at ttyUSB1, while the default CGEM file (I always keep a backup of how it was before when it worked) had ttyUSB0. So somewhere that .xml file was changed, but I have not been able to figure out how or where.

Anyway, right now everything is working, Kstars runs, all the equipment connects, I can run VPN on my laptop (in the garage, where it is warm) to control everything and when I need a screen at the scope I can use the tablet, running android VPN viewer on a fixed address on the RPI and the tablet usb tethered. I went to usb tethering because the wifi connection right at the scope could be iffy depending on which side of the scope I was standing with the tablet. The tethered connection is very fast and reliable (does real time updates during polar alignment and focusing).

It seems there is always something that causes a delay in getting the system running at night, so I have gone to getting everything up and running during the day and then just rolling the scope out at night, so fortunately I did not lose any "scope time" because of this. All the same, I wish these 'computer' issues did not happen. They are far more numerous than any other equipment problems.

thanks for looking anyway.
