Android Studio No serial number

mansson

The factory reset trick only worked once for me. Now it looks like the serial number is lost permanently. This is a huge problem because not only Android Studio but also systrace.py refuses to cooperate with anonymous boards. I really would like a permanent solution to this issue. I connected a fresh ff board with factory firmware, and it also did not present any serial number to ADB. The HiKey 960 board has some information regarding serial number on https://source.android.com/setup/devices Perhaps we need a similar process?  I think the empty string produced by the 'lsusb' command is a clue. It's USB that can't get hold of the proper string. Why? This is important, the boards are quickly becoming useless...
