I'm actually a newbye... I tried, but I obtained the following:
[root@localhost tmp]# gcc -Wall -o evtest evtest.c
In file included from evtest.c:29:

Which nonsense have I done??:-)

Yes!! Using modules, either keyboard or mouse work, separately, even if
keep not working if passing through the monitor hub. Here follow

OK, perfect, both touchpad and USB mouse works fine.

OK, even if I should mount it manually after having loaded manually
modules. By the way, is it normal that, when I load modules manually, I
should load them in a precise order (usbcore, input, hid, usb-ohci, keybdev
(or mousedev)) for avoiding loading errors and obtain correct working?

Indeed, the keyboard has a PS\2 mouse port. And this may be a momentary
solution, waiting for monitor hub working: I plug the keyboard in the USB
port, a PS/2 mouse in the keyboard PS/2 port (one plug less to connect and
disconnect when I take the laptop away and back home:-)), and load both
keyboard and mouse modules. It works really fine, even if mouse is quite
slow if I switch to Win98: worse for it!
Thank you Brad, Harold and Randy for your kind and careful help!
