Hi,

I cannot get works actually hotplug with a simple usb keyboard :

or the lsusb output attached.

It load the keybdev module but i believe is a STATIC_MODULES that get
loaded all the time ?

We (mandrake) currently plan to use usbd which works great and detect
the usbkbd without any problem via :

class 0x03 subclass 0x00 protocol 0x01 prio 2 kmod usbkbd
class 0x03 subclass 0x01 protocol 0x01 prio 2 kmod usbkbd

i have also to setup a :

post-install usbkbd modprobe keybdev

in my /etc/modules.conf

i have not yet looked too much at the how hotplug works, let me know
if it's the normal behavior...
