What techniques do others use to trouble shoot sleep state problems? I have experiemnted with IRPtrace http://www.tssc.de/index.htm# event viewer and simply pulling devices. There has to be a better way!

In general we don't attempt to trouble shoot them.
The problems are often deep inside 3rd party device drivers for which we don't have the source code.
But when we did the device driver for our own USB device, we spent many months working on the power control aspect of the driver (sleep & hibernation). It is an extremely complex area, and very badly documented. So it is very hard to get right from a programming point of view, and as anyone with a Windows PC know many device manufacturers fail to get it right.
