With USB 2.0 and new mice, it's not an issue,<BR>PS/2 is not hot swap and I fried 2 keyboards by hotplugging them in HP dx2400s (HP probably cut costs and removed fuse).

I have another PS/2 MS Intellimouse that I use for those tasks. However, switching mice gets tireing pretty quick. Is there something I can use to connect two PS/2 mice to my system at once?

The pointer shipped with a then-standard PS/2 port but also worked with USB when using the included adapter. What you may not know is that this small, green adapter was purely a mechanical component.
