hi,
for this experiment, i am using linux-2.4.23.
i removed usb subsystem and input core support fully.
if i connect any usb devices, linux should not recognize the usb device. am i right?
but i connected my ps/2 keyboard through ps/2 to usb connector on usb port. it is nicely working.
this result was very strange to me.
i attached my system boot messages and .config file please have look at it and tell me what went wrong?.
boot message...
