I wasn't able to get lmilk to work. I've build my own cheep i2c-monitor (http://www.vdr-portal.de/board/thread.php?postid=639818#post639818). It can record i2c transmissions with a peak rate of 250kHz. The overall speed is limited by the serial interface with a rate of 1.5MBaud. It isn't necessary to use a second PC to monitor a windows driver. - Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
