As requested, I'm sending my dmesg output when connecting an external TV-grabber box. I got the box from my dad and he really can't remember how he got it. It seems to be quite decent quality - yet it is only labeled "USB 2.0 TV BOX". IMHO a truly no-name grabber :-) Hopefully it can be identified as one of the existing cards from the list in dmesg. Here goes: [249160.380080] usb 1-4: new high speed USB device using ehci_hcd and address 7 [249160.530722] usb 1-4: configuration #1 chosen from 1 choice [249160.615476] Linux video capture interface: v2.00 [249160.635939] em28xx: New device @ 480 Mbps (eb1a:2820, interface 0, class 0) [249160.636101] em28xx #0: chip ID is em2820 (or em2710) [249160.794940] em28xx #0: i2c eeprom 00: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794947] em28xx #0: i2c eeprom 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794952] em28xx #0: i2c eeprom 20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794958] em28xx #0: i2c eeprom 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794963] em28xx #0: i2c eeprom 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794968] em28xx #0: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794973] em28xx #0: i2c eeprom 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794977] em28xx #0: i2c eeprom 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794982] em28xx #0: i2c eeprom 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794987] em28xx #0: i2c eeprom 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794992] em28xx #0: i2c eeprom a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.794997] em28xx #0: i2c eeprom b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.795002] em28xx #0: i2c eeprom c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.795007] em28xx #0: i2c eeprom d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.795012] em28xx #0: i2c eeprom e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.795017] em28xx #0: i2c eeprom f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [249160.795023] em28xx #0: EEPROM ID= 0xffffffff, EEPROM hash = 0x00000000 [249160.795024] em28xx #0: EEPROM info: [249160.795025] em28xx #0: I2S audio, 3 sample rates [249160.795026] em28xx #0: USB Remote wakeup capable [249160.795027] em28xx #0: USB Self power capable [249160.795028] em28xx #0: 200mA max power [249160.795030] em28xx #0: Table at 0xff, strings=0xffff, 0xffff, 0xffff [249160.811443] Unknown Micron Sensor 0x00ff [249160.811445] em28xx #0: Identified as Unknown EM2750/28xx video grabber (card=1) [249160.825687] em28xx #0: found i2c device @ 0x4a [saa7113h] [249160.841817] em28xx #0: found i2c device @ 0xa0 [eeprom] [249160.846685] em28xx #0: found i2c device @ 0xba [webcam sensor or tvp5150a] [249160.848931] em28xx #0: found i2c device @ 0xc6 [tuner (analog)] [249160.859431] em28xx #0: Your board has no unique USB ID and thus need a hint to be detected.
