I have a box of PSUs that supply the NUC, Camera/USB hub and everything else. It allows me to separate clean and dirty supplies and also switch them independently. I feed this into a steel box which houses all my modules, with fusing and toggle switches, as described in my book. I recently decided to add a 4-way USB controlled relay, for switching the DC power on and off to the culprits. I can reset my camera, mount (48V), focuser and an external port through an ASCOM driver I wrote. I then have a web controlled power relay to the NUC. I have them all set to ‘normally closed’ and can override that with a simple application. On the few occasions I have issues, a power reset normally works. If the USB itself gets confused, it normally requires a PC reboot, since the hub is drawing power from the NUC and turning the hub power power supply off does not reset it. The NUC is set up to boot up on power, so if I shut it down and turn off its power and then turn it back on, it does a full reboots of it and the USB system.
