Hi,
Is there any kernel module to load in order to add support to a ps/2 mouse?
My problem: while trying to add support for my ps/2 mouse in my system
running a 2.4.18-686-smp kernel (woody+security updates), the only way I
found to get it was to load the usb-ohci kernel module :-/
Indeed, [...]
Any way (other than using USB kernel code) to add support to my ps/2
mouse (a simple Logitech 3btns+wheelscroll with 6 pins ps/2 connector)?
That's odd. I'd bet that usb-ohci is loading another module, though,
like 'psaux' or 'mouse'...run 'lsmod' to see, and then just loading that
should be enough in the future.
I did suspect that also, but could not find anything special with lsmod.
Below is some shell output:

Once again, if then I unload usb-ohci and usbcore, 'cat /dev/psaux'
prints some characters (until I reboot my system of course!).
Thanks
