I found a way to make it work! A workaround is to unload the ehci_hcd
module. The following command (all in one line) accomplishes this for
gnome-power-manager.
echo 'SUSPEND_MODULES="ehci_hcd"' | sudo tee /etc/pm/config.d/lenovo3000v100
Now, I don't understand why this is necessary, since according to
/etc/default/acpi-support "network cards and USB controllers will automatically
be unloaded unless they're listed in MODULES_WHITELIST". This should already be
automatically unloaded, and it's not. Maybe this is another bug.
