Herbert is correct....

Way back in the days of Windows 3, if a mouse or keyboard were
disconnected, the OS quit responding and the user needed to reboot
in order for Windows to "see" the device again.  But there has never
been any major electrical/electronic danger from connecting or
disconnecting a keyboard or mouse..

Yes there is a possibility of electrical arcing at the moment of contact,
but the current levels are soooo low that this danger is almost negligible.
And the danger would be focused more toward the mouse or keyboard
not the MoBo -- mice and keyboards do not have a voltage source.
They each DRAW their current FROM the MoBo.

Printers, scanners, and other devices with their own power supplies
are excluded from this conversation for obvious reasons.
