How do I bypass the RSA authentication dialog box to enable controlling phone from adb?
This was solved using clues from this post  


  If you only need to authorize one computer:
   Simply copy the adbkey.pub
  onto the device location:
    /data/misc/adb/ and rename it from
  adbkey.pub to adb_keys
   chmod 0644 and then reboot.  


I forgot to do the chmod but still works.
