Hi, I recently purchased a Delock USB 2.0 Video Grabber http://www.delock.de/produkte/gruppen/Multimedia/Delock_USB_20_Video_Grabber_61534.html which windows recognises as a USB PVR-TV device. The drivers on the cdrom which came with the device seem to be from 2009 whereas the ones on the website are from 2008. On Ubuntu Lucid and Debian Sid plugging it into the host it produces the following dmesg output: [ 301.050914] usb 1-7: new high speed USB device using ehci_hcd and address 5 [ 301.201825] usb 1-7: configuration #1 chosen from 1 choice [ 301.412395] Linux video capture interface: v2.00 [ 301.469956] em28xx: New device @ 480 Mbps (eb1a:2861, interface 0, class 0) [ 301.470129] em28xx #0: chip ID is em2860 [ 301.636076] em28xx #0: i2c eeprom 00: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636112] em28xx #0: i2c eeprom 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636144] em28xx #0: i2c eeprom 20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636173] em28xx #0: i2c eeprom 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636203] em28xx #0: i2c eeprom 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636232] em28xx #0: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636262] em28xx #0: i2c eeprom 60: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636292] em28xx #0: i2c eeprom 70: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636323] em28xx #0: i2c eeprom 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636354] em28xx #0: i2c eeprom 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636385] em28xx #0: i2c eeprom a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636417] em28xx #0: i2c eeprom b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636449] em28xx #0: i2c eeprom c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636482] em28xx #0: i2c eeprom d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636513] em28xx #0: i2c eeprom e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636543] em28xx #0: i2c eeprom f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 301.636575] em28xx #0: EEPROM ID= 0xffffffff, EEPROM hash = 0x00000000 [ 301.636582] em28xx #0: EEPROM info: [ 301.636588] em28xx #0: I2S audio, 3 sample rates [ 301.636593] em28xx #0: USB Remote wakeup capable [ 301.636599] em28xx #0: USB Self power capable [ 301.636605] em28xx #0: 200mA max power [ 301.636613] em28xx #0: Table at 0xff, strings=0xffff, 0xffff, 0xffff [ 301.650582] em28xx #0: Identified as Unknown EM2750/28xx video grabber (card=1) [ 301.664828] em28xx #0: found i2c device @ 0x4a [saa7113h] [ 301.681079] em28xx #0: found i2c device @ 0xa0 [eeprom] [ 301.681452] em28xx #0: found i2c device @ 0xa2 [???] [ 301.681825] em28xx #0: found i2c device @ 0xa4 [???] [ 301.682200] em28xx #0: found i2c device @ 0xa6 [???] [ 301.682574] em28xx #0: found i2c device @ 0xa8 [???] [ 301.682950] em28xx #0: found i2c device @ 0xaa [???] [ 301.683324] em28xx #0: found i2c device @ 0xac [???] [ 301.683698] em28xx #0: found i2c device @ 0xae [???] [ 301.699705] em28xx #0: Your board has no unique USB ID and thus need a hint to be detected.
