The "root hub lost power" etc is normal.

The other message indicates that a child device (for ep0) was resumed
before the parent was, or that at least the driver model records for
that linkage became corrupt.  No, it's not normal to violate either kind
of system integrity constraint ...

Well, resume sequencing issue for ep00 is a USB stack issue, and since
ACPI isn't speaking to us in English (or even Linux-ese) it's hard to
say what that means.  I don't anything outside of drivers/acpi knows
a thing about what a "fixed event" is, but maybe there's a translation
to more traditional terminology that would make sense.
