The USB connection for power will double as a serial port which allows one into the device from a terminal emulator but it does not provide a full network connection. To use maiden one has to connect via wifi (either in hotspot mode of router mode).
This is most likely the known problem with connection to wifi after the device has been off for awhile. Norns does not have a internal clock, when it gets a network connection it tries to sync its clock. The large jump in time causes supercollider to freak out. If you give it some time it will usually come back (in a minute or two). If it doesn’t reset/reboot from the bottom on the bottom of the case and try again a second time- the second and subsequent times things usually work.
We’re activity trying to improve things in the area.
