Hello !
I have an old hardware based on lga775 (see zip file for all devices) but It works very well with last Catalina 10.15.7
Since big sur update no keyboard and mouse is detected !
Big sur boots very well, all usb ports work well, when i plug an usb key i can see it on desktop.
But when i plug my keyboard or my mouse on each usb port, none is detected !
An idea ?
Thanks in advance
stev
