Hi Mandar,

By talking to the usb/kernel drivers, like the hotplug program does.

There are a few different ways to get USB keyboard support working, make sure you're using the correct way for your particular setup.

I have my own tiny distro called Puppy Linux, and I have only just got usb keyboard and mouse working (latest version 0.8.5).

I also did not know how to auto-detect the keyboard. I did this:

modprobe usbkbd modprobe usbmouse cat /proc/usb/devices | grep "keyboard", I'm typing this from memory, hope it's right. If "keyboard" cannot be found, unload those two modules.

For usb mouse, you only need: modprobe usbmouse

This is only if you have usbkbd and usbmouse turned on and as modules in the kernel config file.
