I cannot access the phone via adb. Although I cannot be completly sure if I have all requisites done on my ubuntu linux system, I do wonder that "usb debugging" doesn't show up when the phone is connected to my pc via USB cable. Today I did a full wipe and a clean install of the last WIUI-verision 13-11-8. Anyone else? Or does "usb debugging" show up when activated in developer options and connected?
