Android Studio No serial number

samson.lai

請問為什麼rk3399的板子沒有serial number

下面是studio所顯示的錯誤訊息

com.android.ddmlib.AdbCommandRejectedException: device '(no serial number)' not found
Error while Installing APK

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...
