I’m pretty sure replugging ps/2 didn’t ever crash the system for me. Anything com-port related or vga didn’t either. Now hotplugging pci wasn’t the best idea,

I’m pretty sure replugging ps/2 didn’t ever crash the system for me. Anything com-port related or vga didn’t either. Now hotplugging pci wasn’t the best idea, but it’s on the inside of the machine, so you naturally power it off.

replugging a mouse via ps2 either crashed the thing or just simply didn't work. same with keyboard

  Every computer where I've replugged a ps/2 mouse, it worked just fine. If I booted without one, then plugged one in, it wouldn't work, but that is a separate issue.

    "Every computer where I've replugged a ps/2 mouse, it worked just fine." PS/2 is not a hot-swappable port, by design. Your hot-swap adventures mean you started out using more modern motherboards (2010-ish) which simply have an internal USB-PS/2 adapter for presenting PS/2 ports.

      No, most of my experience was something like 2004 Dells. If it was running off USB, then plugging in a mouse after boot would have worked. But it didn't. Only re-plugging worked.

        Most PS/2 issues were already mitigated by that point. I specifically remember having a problem on our Windows 2000 Server box that would require a reboot any time the keyboard was un/replugged.

I remember serial mice being iffy. ps/2 didn't give me problems. parallel and scsi would cause crashes, but it was kind of expected.

  in my experience, having done lots of programming with it, rs232 serial ports are always repluggable without problems, unlike ps2.

in theory hotplugging a ps/2 keyboard or mouse could blow your motherboard but it always worked fine for me

  About that... Many years ago family member asked me how to transfer photos from their Symbian phone onto PC. Over the years they have been conditioned to absolutely never plug or unplug anything from the computer while it is turned on. It took quite some time to convince them that USB is designed for hotplugging. But the moment we connect it, computer totally freezes. With egg on my face I think, oh, probably just Windows XP crashed. Power-cycling doesn't help at all though, no POST, no beeps, absolutely nothing. Out of ideas I open the computer case, only to see there's a huge bulge on the chipset... I have no idea what happened there. Perhaps unlucky short when inserting connector, causing latch-up in the chip? Phone was totally fine after this, I connected it to different PC without issues.

    oh man, condolences! i bet it took them a long time to start hotplugging usb after that
