I'm attaching to messages with debug (hw.usb.uhub.debug=16) enabled:

msg3:

-- device was not attached on power-on boot
-- set
   # sysctl hw.usb.uhub.debug=16
-- attaching the device at 14:28:03++
-- device successful seen at 14:28:05



msg4:

-- device was not attached on power-on boot
-- set at 10:21:08
   # sysctl hw.usb.uhub.debug=16
-- attaching the device at 10:21:08++
-- not seen until reboot at 10:21:37


I only see in msg4 that there is nothing to see :-)
