Problem Random operation of the USB connection
I still have trouble connecting with the pro server ... This morning, I turn on my prusa MK3 and repetier is working properly and this afternoon, the connection does not seem to work .... Once again, I reinstalled the last image rpi 0.92.2, (why is not there the last image rpi in 0.92.3?) on my side the update in WIFI does not work and crashes as usual. I feel that the USB connection does not work (the rpi port is disabled on the Prusa). I do not know what and I'm a little tired of fighting with unstable versions. what should I do again this time? At startup I have ports that scrolls that did not show up before. What to do to have the USB connection?
I tried to change USB cables, change the USB ports on the RPI ect ... I specify that when the re-i stallation completes the connection works but if I turn off the printer and the server and then I restart it does not work anymore
