# new adbd instance after init relaunches it. So now we force the USB bus to reset
# here when adbd sets the service.adb.root property to 1.  We also restart adbd here
# rather than waiting for init to notice its death and restarting it so the timing
# of USB resetting and adb restarting more closely matches the previous behavior.
