Yeah - very useful, thanks.

Not good...

Interesting.  I don't know what it means :-) but try using pci=routeirq on
the boot options.

OK, this is initializing the USB controller and it looks serious.  So try
booting with the irqpoll option.

This is really interesting - it's the controller for the USB 2.0 devices. 
Are you certain _they_ don't work?  It looks as if perhaps low-speed
devices won't, while high-speed devices might.

This has absolutely nothing to do with your problem.  I'm simply stunned
that anybody thought a speaker was an input device! :-)

OK, this looks like you plugged in a USB 2.0 device and it didn't work.  I'd
say try rebooting with the irqpoll option as suggested.  You can also try
acpi=off and acpi=noapic (the latter is, I think, unrelated, but it's
interesting that I saw four APIC errors reported).
