Computer mouse of pre USB days. I am in deep trouble with my loading Windows 11. I am trying to back track and load windows 7 onto a clean machine but it does not recognize the mouse. Absolutely nothing on the internet helps. I thought that if I could try a pre USB wired mouse, that might do the trick because the trouble seems to lie in the USB area. I used to have a wired mouse with a green and purple plug. I threw it out ages ago; bad mistake it seems. If anyone can help it might just save my sanity.
