I have a T510 running Ubuntu 10.9 that has this problem.
A work around seems to be to connect the USB through a powered hub. Even if it has lost the USB from a suspend, plugging in a USB mouse or my cell phone does nothing (not even power to the cell phone); however, if I plug in an externally powered hub, full USB functionality recovers.
