Then avoiding the failed firmware is no solution, indeed.
If it's a new probe, it should be never executed during resume.

Can you expand this comment?  What's wrong with probing during resume?

Well, if the probe requires the access to a user-space file, it can't
be done during resume.  That's the very problem we're seeing now.
The firmware loader can't help much alone if it's a new device
object.

The USB stack does carry out probes during resume under certain
circumstances.  A driver lacking a reset_resume callback is one of
those circumstances.

So, having a proper reset_resume in btusb would help in the end?
