You are right, it seems like there is a third chip on the bottom side. But it is very hard to get to it, and I don't think I could do this without risking to destroy something. But I made some USB-Sniffs. While doing this, I noticed the logfile grows to lots of megabytes in some seconds of idle state. It seems like the host is continously sending the numbers from 0 to 255. Is there some tool to edit usbsnoop logfiles? It would be difficult to delete the boring parts with sed/awk and I definitely can't distribute a 50Mb logfile. PyroPeter
