No, and I'm not going to post one until the pvUSB stuff gets in, since that work will involve refactoring the pvUSB code into PV and DEVICEMODEL paths, and I don't fancy having to repeat that work every time there's another revision. :-) The core technology is working just fine; it's only the library interface that really needed work in the last patch, and that will be set by the pvUSB series. So once that's in, it should be a relatively small amount of work. -George
