Hello Zdenek, Antti I have some spare time to do some work. First step I need to make USBsnoop working to see where firmware upload goes. Those logs I posted seem a little bit broken, right, because XP crashes and system reboots when usbsnoop enabled. But anyway usbsnoop capture some data. Antti, can you post a part of usbsnoop log where firmware is loaded? Regards, Ivan >> Correct firmware can be downloaded from: >> http://palosaari.fi/linux/v4l-dvb/firmware/af9013/ >> >> Your sniffs seems to be a little broken where firmware download was made. >> >> You should hack cx88 driver for USB-bridge.
