Congratulations this is a great forum
I have old machines and several mouse and keyboards with sp/2 , din and serial port
And i like use them sometimes
But Lastest updates win7/8/10 (if you sometime input usb keyboard or mouse in past) disable serial, ps/2 and din ports, mouse and keyboard, into win7/8/10, INCLUDE on boot, do You know why?
I think is the generic driver of chipset and bios of windows for older hardware, that change something in ACPI,
Some Autoexec.bat update change probally.
But i don't know!
I see on internet many people witn the same problem and they can't fix througth update or delete drivers
I think is something on dependency tree instalation drivers
Can You help?
Thanks from Brasil
