I just bought a Terratec Grabby hardware revision 2 in hopes that it would work on my linux box. But alas, I got only sound working. It seems that analog video picture grabbing does not work. I tried kernels 3.4.34-grsec, 3.7.1 (vanilla), 3.8.2-grsec and 3.9.0-rc4 (vanilla). And all fail the same way - no video data received. The USB ID is same as on the revision 1 board: Bus 005 Device 002: ID 0ccd:0096 TerraTec Electronic GmbH And it is properly detected as Grabby. It seems that the videobuf2 changes for 3.9.0-rc4 resulted in better debug logging, and it implies that the application (ffmpeg 1.1.4) is behaving well: all buffers are allocated, mmapped, queued, streamon called. But no data is received from the dongle. I also tested mencoder and it fails in similar manner. Dmesg (on 3.9.0-rc4) tells after module load the following: [ 1249.600246] em28xx: New device TerraTec Electronic GmbH TerraTec Grabby @ 480 Mbps (0ccd:0096, inte rface 0, class 0) [ 1249.600258] em28xx: Video interface 0 found: isoc [ 1249.600264] em28xx: DVB interface 0 found: isoc [ 1249.600443] em28xx: chip ID is em2860 [ 1249.715053] em2860 #0: i2c eeprom 00: 1a eb 67 95 cd 0c 96 00 50 00 11 03 9c 20 6a 32 [ 1249.715084] em2860 #0: i2c eeprom 10: 00 00 06 57 0e 02 00 00 00 00 00 00 00 00 00 00 [ 1249.715110] em2860 #0: i2c eeprom 20: 02 00 01 00 f0 10 01 00 00 00 00 00 5b 00 00 00 [ 1249.715136] em2860 #0: i2c eeprom 30: 00 00 20 40 20 80 02 20 01 01 00 00 00 00 00 00 [ 1249.715161] em2860 #0: i2c eeprom 40: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715186] em2860 #0: i2c eeprom 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715211] em2860 #0: i2c eeprom 60: 00 00 00 00 00 00 00 00 00 00 32 03 54 00 65 00 [ 1249.715235] em2860 #0: i2c eeprom 70: 72 00 72 00 61 00 54 00 65 00 63 00 20 00 45 00 [ 1249.715261] em2860 #0: i2c eeprom 80: 6c 00 65 00 63 00 74 00 72 00 6f 00 6e 00 69 00 [ 1249.715286] em2860 #0: i2c eeprom 90: 63 00 20 00 47 00 6d 00 62 00 48 00 20 03 54 00 [ 1249.715311] em2860 #0: i2c eeprom a0: 65 00 72 00 72 00 61 00 54 00 65 00 63 00 20 00 [ 1249.715336] em2860 #0: i2c eeprom b0: 47 00 72 00 61 00 62 00 62 00 79 00 48 00 00 00 [ 1249.715361] em2860 #0: i2c eeprom c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715385] em2860 #0: i2c eeprom d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715410] em2860 #0: i2c eeprom e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715435] em2860 #0: i2c eeprom f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [ 1249.715464] em2860 #0: EEPROM ID= 0x9567eb1a, EEPROM hash = 0xd3498090 [ 1249.715470] em2860 #0: EEPROM info: [ 1249.715475] em2860 #0: AC97 audio (5 sample rates) [ 1249.715480] em2860 #0: 500mA max power [ 1249.715487] em2860 #0: Table at 0x06, strings=0x209c, 0x326a, 0x0000 [ 1249.715495] em2860 #0: Identified as Terratec Grabby (card=67) [ 1250.058076] em2860 #0: Config register raw data: 0x50 [ 1250.076845] em2860 #0: AC97 vendor ID = 0x60f160f1 [ 1250.086814] em2860 #0: AC97 features = 0x60f1 [ 1250.086822] em2860 #0: Unknown AC97 audio processor detected!
