# This property trigger has added to imitiate the previous behavior of "adb root".

# The adb gadget driver used to reset the USB bus when the adbd daemon exited,

# and the host side adb relied on this behavior to force it to reconnect with the

# 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.
