Are you sure it is stock 3.7.10 Kernel, not some media build top of that? For some reason em28xx driver skips USB ID based detection and fall-backs to I2C bus / eeprom fingerprint detection that naturally fails. regards Antti On 05/09/2013 11:29 AM, Eric Sander wrote: > Sorry, here some more info: > > lsusb: > Bus 001 Device 002: ID 2013:0251 PCTV Systems > > cat /proc/version > Linux version 3.7.10-1.4-desktop (geeko@buildhost) (gcc version 4.7.2 > 20130108 [gcc-4_7-branch revision 195012] (SUSE Linux) ) #1 SMP PREEMPT > Fri Apr 19 12:06:34 UTC 2013 (8ef74f8) > > Opensuse 12.3 > > On 09.05.2013 09:13, Eric Sander wrote: >> Hi There, >> i have the TV-USB-Stick: pctv QuatroStick nano it is misdetected as >> Sharp S921 >> >> dmesg-log: >> [ 1080.044027] usb 1-7: new high-speed USB device number 7 using ehci_hcd >> [ 1080.159731] usb 1-7: New USB device found, idVendor=2013, >> idProduct=0251 >> [ 1080.159738] usb 1-7: New USB device strings: Mfr=1, Product=2, >> SerialNumber=3 >> [ 1080.159744] usb 1-7: Product: PCTV 520e >> [ 1080.159748] usb 1-7: Manufacturer: PCTV Systems >> [ 1080.159752] usb 1-7: SerialNumber: 00000010JR7F >> [ 1080.160066] em28xx: New device PCTV Systems PCTV 520e @ 480 Mbps >> (2013:0251, interface 0, class 0) >> [ 1080.160070] em28xx: Audio Vendor Class interface 0 found >> [ 1080.160073] em28xx: Video interface 0 found >> [ 1080.160076] em28xx: DVB interface 0 found >> [ 1080.161045] em28xx #0: chip ID is em2884 >> [ 1080.256727] em28xx #0: found i2c device @ 0xa0 [eeprom] >> [ 1080.268726] em28xx #0: Your board has no unique USB ID. >> [ 1080.268732] em28xx #0: A hint were successfully done, based on i2c >> devicelist hash. >> [ 1080.268736] em28xx #0: This method is not 100% failproof. >> [ 1080.268738] em28xx #0: If the board were missdetected, please email >> this log to: >> [ 1080.268741] em28xx #0: V4L Mailing List >> >> [ 1080.268745] em28xx #0: Board detected as EM2874 Leadership ISDBT >> [ 1080.352018] em28xx #0: Identified as EM2874 Leadership ISDBT (card=77) >> [ 1080.352097] em28xx #0: Config register raw data: 0x1e >> [ 1080.352844] em28xx #0: AC97 vendor ID = 0x8ca38ca3 >> [ 1080.353476] em28xx #0: AC97 features = 0x8ca3 >> [ 1080.353481] em28xx #0: Unknown AC97 audio processor detected! >> [ 1080.375722] em28xx #0: v4l2 driver version 0.1.3 >> [ 1080.403724] em28xx #0: V4L2 video device registered as video0 >> [ 1080.404172] em28xx-audio.c: probing for em28xx Audio Vendor Class >> [ 1080.404176] em28xx-audio.c: Copyright (C) 2006 Markus Rechberger >> [ 1080.404179] em28xx-audio.c: Copyright (C) 2007-2011 Mauro Carvalho >> Chehab >> [ 1080.422057] s921: s921_attach: >> [ 1080.422066] DVB: registering new adapter (em28xx #0) >> [ 1080.422076] usb 1-7: DVB: registering adapter 0 frontend 0 (Sharp >> S921)... >> [ 1080.422677] em28xx #0: Successfully loaded em28xx-dvb >> [ 1080.796252] em28xx #0: submit of audio urb failed >> >> feel free to ask if you have further questions. >> > > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- http://palosaari.fi/
