Hi all,

I have a platform without PS/2 keyboard that there are USB ports only.
So I can use USB keyboard to instead of PS/2 keyboad.
But I have a question now on Red Hat Linux 9.0 or Fedora.
When installing, it will show lots of error message like this: "pc_keyb: controller jammed (0xFF)".
After installing, it shows the same message again.
Someone suggests me to modify the file which is in linx/drivers/char/.

#ifndef kbd_controller_present
#define kbd_controller_present() 1
#endif

By changing kbd_controller_present() to '0' instead of '1' and compile the kenel again.
Indeed, we have no error message.
But we can not use USB keyboard any more.

I don't understand. Why?

Anyone can tell me that what is "pc_keyb.c" ?
How to solve this issue?

Thanks all,
Max
