ah, sweet!
I can confirm that it makes difference.
Before I had to reload usbkbd module to make remote work.
Now, I can reload usbhid module to make remote work.
So it is progress.
However, once I unplug remote and plug it in, I still need to reload
either of the modules. There does not seems to more sleep routines in
'core' and 'host' directories, so I guess it is something else.
