IBMPC: Sporadic hotplug failure for PS/2 mouse #718

Closed Bmkool closed 2 years ago

Bmkool commented 2 years ago

I've ran across a few scenarios where a PS/2 mouse fails to re-connect after hotplugging. The converter is then frozen and not functional for that port until the processor is restarted.

This tends to happen when: 1) Nothing is plugged into the PS/2 port when powered on and plugged in later

    USB configured.

    Loop start.

2) Unplugged during the initialization process

I have not experienced any issues hotplugging a keyboad.

I'm also aware of the issue. I'll look into when I have time.
