Actually, I was just editing my original message with the fact that I have been looking around and found that hidd is actually deprecated in favor of input service through dbus, which is probably how it works in maemo.
Since I am not very familiar with dbus, can anyone explain how exactly does it work and what command is used to actually activate the input service and connect HID device (keyboard)?

I have read through this link: http://wiki.bluez.org/wiki/HOWTO/InputDevices , but I'm quite lost when it comes to Dbus :-)
