New USB Mouse takes an additional 48 seconds to activate on startup

[shengchieh]

I wonder if the slowdown is due to cleaning, not the USB keyboard.  Try booting once w/o the USB keyboard and mouse.  If slow, something you did while cleaning messed things up.
If fast, boot w/ just USB keyboard and not USB mouse - and the other way around mouse, but no keyboard.  Debug which is slow and post more information about it.  Also, be sure everything
is plugged in fully (not just the keyboard and mouse - everything).
