The previous update caused all USB devices to fail, as well as the built in trackpad. This claims to have a fix for that, but probably does not fix another bios related issue: Booting the device when AC power is not present results in no mouse cursor. That affects all bioses after 1.52 I'm told. See this bug for more info: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1210748
In short, bios es for this device seem to be in rather bad shape.
I'll endeavor to test the latest, which claims have a fix for the disabling of all USB ports issue, in the next few weeks. Since it lists no other changes in the readme, it's unlikely to address this bug.
