I've been waiting for this for a loooooong time. Thanks to you, Hans Peter and all of the folks who have helped! Not on the FAQ: Q: Other then no longer requiring giant [MPSAFE], what does usb2 give us? Does it fix the battery-eating on laptops? Does it allow the system to reach C3 and lower sleep states? (These are at least closely linked issues.) I have not been running current for a while and this might be enough incentive to get me to kick the tires. -- R.
