To be fair, I would classify that as bug in the USB code.

Huh? The power saving is done by suspending the device if it is not used
for a while. It is not mixed with suspend/resume in any other way.

I am not sure if the assertion in that form is still warranted, Andrew
should be able to comment on that. But I guess for drivers like USB we
really have to do the idle processing from a kernel thread.
