Thanks Volker, I tried this (USB FP2 connection with a PC is no more recognized), this (USB connection to computer not working nor charging), this (Trouble getting USB data connection), and this (Cannot access FP2 via USB). I think it is a data cable as I think it used to work for that purpose, it is this (https://www.subtel.co.uk/CELLONIC-Datacable-for-Fairphone-1-Fairphone-2-USB-Data-Cable-920103.html) - I don’t have another phone or cable that I can check with though.
I don’t get a notification when connected by USB.
