I finally found a solution to run my tunerTV identified as eb1a:2881 and based on em28xx drivers. I have copied the firmware xc3028.fw (found here http://www.steventoth.net/linux/hvr1500/ ) and firmware_v3 (found here http://konstantin.filtschew.de/v4l-firmware/) in the folder /lib/firmware. Then I run these commands sudo rmmod em28xx_dvb sudo rmmod em28xx sudo modprobe em28xx card=10 i2c_scan=1 sudo rmmod em28xx_dvb sudo rmmod em28xx sudo modprobe em28xx card=11 i2c_scan=1 and my tuner works well. I remember that my tuner is this http://www.conitech.it/conitech/ita/prod.asp?cod=CN610DVB-DT and and I use the 2.6.31 kernel of the ubuntu team. Now the output of "dmesg | grep em28xx" is: " [10860.082702] em28xx: New device @ 480 Mbps (eb1a:2881, interface 0, class 0) [10860.082707] em28xx #0: Identified as Hauppauge WinTV HVR 900 (card=10)
