Yes, it is loaded when the driver doesn't work (with the original linux/drivers/media/video/em28xx/em28xx-i2c.c) # lsmod | grep xc3028 xc3028_tuner 9984 0 i2c_core 22656 15 i2c_ec,it87,i2c_isa,eeprom,qt1010,mt2060,mt352,zl10353,xc3028_tuner,tvp5150,tuner,nvidia,em28xx,tveeprom,i2c_nforce2 However, changing the driver source as suggested by Aidan makes the driver to work well. Now, what do you suggest to do? Keep the old driver version (userptr) or use the modified one? Valerio
