Comment (by edglex):
This bug (or very similar, on the same hardware anyway) appeared in linux
and was avoidable using a kernel parameter; pci=nocrs. It was present in
2.6.35 but had disappeared by 2.6.37, I haven't looked at the diffs
between those versions yet, or into what ACPI Current Resource Settings
really are, but presumably there is some workaround in the kernel now.
There is a bug report for this here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/661600
So following this lead I disabled ACPI, and USB works! It's good that
there's a workaround, but it's sort of a rock vs hard place situation
because a laptop without ACPI is a bit limiting, so I will still try to
fix this.
