First, the device showed up as USB device 7640:edc1 (even after several unplug - replug cycles), so I decided to add this VID:PID to the em28xx driver to see what happens. That worked fine, em2882/em2883, tuner xc2028/3028 etc. were detected properly. Later I noticed, that the device now shows up as 2040:6500, which is the expected ID for this device. Since then, the device maintains this ID. I also checked if Windows is involved, but it shows up with the same ID there. Does anyone have an idea what could have happened ??? I wonder if we should add this ID to the em28xx driver... Regards, Frank
