Re: ACPI and USB

[Johannes Erdfelt <johannes-olwfUuQ3Q2lBDgjK7y7TUQ@public.gmane.org>]

HIGHLY unlikely. The USB code relies on the PCI subsystem exclusively
for anything to do with IRQ's.

The PCI subsystem thusly relies on a couple of different subsystems, one
of them being ACPI.

This is not a USB problem.
