I have 2 em28xx USB capture devices - a Hauppauge Win-HVR-950 and a Pinnacle HD stick: Bus 001 Device 007: ID 2304:0227 Pinnacle Systems, Inc. [hex] Pinnacle TV for Mac, HD Stick Bus 001 Device 004: ID 2040:6513 Hauppauge Both of which are em28xx devices. I am running the latest HG pull of the v4l-dvb drivers as of today (6th June 2008). >From a cold start, both devices are seen by the USB probe, however only one gets a /dev/dvb/adapter entry. If I remove the one that did not, I get the following warning: ========== Jun 6 18:00:15 Deathwish kernel: usb 1-3: new high speed USB device using ehci_hcd and address 7 Jun 6 18:00:15 Deathwish kernel: usb 1-3: configuration #1 chosen from 1 choice Jun 6 18:00:15 Deathwish kernel: em28xx new video device (2304:0227): interface 0, class 255 Jun 6 18:00:15 Deathwish kernel: em28xx Doesn't have usb audio class Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate settings: 8 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 0, max size= 0 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 1, max size= 0 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 2, max size= 1448 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 3, max size= 2048 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 4, max size= 2304 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 5, max size= 2580 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 6, max size= 2892 Jun 6 18:00:15 Deathwish kernel: em28xx #0: Alternate setting 7, max size= 3072 Jun 6 18:00:15 Deathwish kernel: em28xx #0: chip ID is em2882/em2883 Jun 6 18:00:15 Deathwish kernel: tuner' 1-0061: chip found @ 0xc2 (em28xx #0) Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 00: 1a eb 67 95 04 23 27 02 d0 12 5c 03 8e 16 a4 1c Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 10: 6a 24 27 57 46 07 01 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 20: 46 00 01 00 f0 10 02 00 b8 00 00 00 5b 1c 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 30: 00 00 20 40 20 80 02 20 01 01 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 40: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 60: 00 00 00 00 00 00 00 00 00 00 24 03 50 00 69 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 70: 6e 00 6e 00 61 00 63 00 6c 00 65 00 20 00 53 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 80: 79 00 73 00 74 00 65 00 6d 00 73 00 00 00 16 03 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom 90: 50 00 43 00 54 00 56 00 20 00 38 00 30 00 30 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom a0: 65 00 00 00 1c 03 30 00 37 00 30 00 38 00 30 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom b0: 31 00 30 00 36 00 31 00 33 00 37 00 33 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 54 00 Jun 6 18:00:15 Deathwish kernel: em28xx #0: i2c eeprom f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Jun 6 18:00:15 Deathwish kernel: EEPROM ID= 0x9567eb1a, hash = 0x2de5f5bf Jun 6 18:00:15 Deathwish kernel: Vendor/Product ID= 2304:0227 Jun 6 18:00:15 Deathwish kernel: AC97 audio (5 sample rates) Jun 6 18:00:15 Deathwish kernel: 500mA max power Jun 6 18:00:15 Deathwish kernel: Table at 0x27, strings=0x168e, 0x1ca4, 0x246a Jun 6 18:00:15 Deathwish kernel: xc2028 1-0061: creating new instance Jun 6 18:00:15 Deathwish kernel: xc2028 1-0061: type set to XCeive xc2028/xc3028 tuner Jun 6 18:00:15 Deathwish kernel: xc2028 1-0061: Loading 80 firmware images from xc3028-v27.fw, type: xc2028 firmware, ver 2.7 Jun 6 18:00:15 Deathwish kernel: xc2028 1-0061: Loading firmware for type=BASE MTS (5), id 0000000000000000.
