Sorry if I quote myself again , but I think to have understood why my system hangup at installation .
The default IRQ that my motherboard sets for USB 2.0 controller and the Sound Card is "12" if no PS/2 mouse is plugged-in (generally IRQ12 is reserved to PS/2 mouse) , but the PS/2 Mouse port is always present , also if no mouse is plugged-in , and the linux PS/2 mouse driver occupies the IRQ 12 when loads , so , when it's the time of the USB 2.0 controller driver the booting hangs up.
Is not possible adding a feature in the kernel , that if the PS/2 driver doesn't find any mouse plugged in the port just leve free the IRQ12 instead of catching it up? (if this feature is not already implemented , but it is doesn't work for me)
