Hi Philippe,

To boot with SMP kernel you have to build boot image in which io-hid and devc-con-hid both launch on the same CPU core. 
To do this you should use on -C0, for example:

on -C0 /proc/boot/io-hid -dusb /dev/io-usb/io-usb
waitfor /dev/io-hid/io-hid
on -C0 /proc/boot/devc-con-hid -n5 &
reopen /dev/con1

Let me know how it works on your configuration.

Respectfully,
Oleg
