I've only done a HID driver, all of the usb code was already there, and
btw, all of the configuration is in usbd outside the kernel. The kernel seems
to configure (almost) the bare minimum in usb(3).

I'd like to keep the usb stack outside the kernel just while seeing errors;
once it gets stable, I don't know if I wouldnt want to put it all back in the kernel
just to avoid complexity (more file systems, more binds, more levels of
indirection, etc.).

Regarding 2.0, I'm in the mood of using usb for almost any new piece of hw
we buy that is not integrated inside the PC. This means that sooner or later
we'll have usb 2.0, it depends on who needs this earlier, if we or other 9fans.
