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

no mouse cursor. That affects all bioses after 1.52 I'm told.
Apologies for all the comments. Above links are for s230u 3347-2hu. Your
mileage may vary.

The very latest bios (1.65 I think?) actually renders all usb devices

Tested latest upstream kernel 3.15 (and disabled workaround described

Note that the first few suspends are often successful (either kernel).
I'm still trying to figure out what the key element is that gets the

Found a workaround on a similar bug that is now closed:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213233
It seems to work:
Add the following to: /etc/rc.local
if grep -q "EHC1.*enabled" /proc/acpi/wakeup; then
echo EHC1 > /proc/acpi/wakeup
