I did a USB snoop for a few different situations--preview, scan, and calibrate, but I've run into a snag- there are some USB control messages I don't understand, and their values are not listed in genesys_low.h. They seem to be fairly important messages because there are very many of them, and their data strings change constantly. Furthermore, the gl841 spec doesn't appear to have the USB protocol listed, so I'm at a loss here.. Where did you find the control message values that are listed in genesys_low.h? Luke
