powertop is not running. I'm not sure how to check the rest :/
Something like this: find /sys/ -xdev -path '*usb*/power/control' -exec grep -H -e ^ -e auto {} + "on" means the device is permanently powered up. "auto" means it'll turn off when idle. I'm not sure what they should be *in general*, but a couple of times I've hit problems with devices misbehaving and forcing their power from "auto" to "on" helped.
