First of all, most (all) PS/2 devices are not designed to be
hotplugged. Depending on the BIOS, it may disable the PS/2 mouse
connection if there is not a mouse plugged in at boot. There may be
a BIOS setting for this. But if I remember correctly, this is a
choice of off or auto.

Depending on your hardware, you may also be running the risk of
destroying the PS/2 device or motherboard circuitry.
