I wanted to mean: moving the firmware loading *triggering* all in kernel,
with the future UART device enumeration. Or do you still see a benefit to
keep the "attach" step in user space, to cover some specific use cases
maybe?

I'll keep following the serial bus discussions, this is a every interesting
evolution.

Thanks again,
