We had issues with all TTYs reading out on nnrpi1, I have moved them from an apparently faulty USB hub to a new one.
Trying to reboot the pi to detect the new USB ports and it didn't recover from boot
Trying to repair SD card but I get a lot of errors on my laptop, indications are the SD card is completely dead
A new SD card will be ordered and nnrpi1 restored from the original images

A new USB hub should also be organised as it seems one is faulty (pi hangs if 3 or more USB devices connected to it)
