Hi again! following the thread "em28xx: new board id [eb1a:5051]" between Reuben and Gareth I was able to advance a little: 1) I opened the usn stick and my chipsets are: - USB interface: em2860 - Audio ADC: emp202 - Video ADC: saa7118h (philips) 2) I confirm that the stock em28xx driver can recognize the usb stick but needs to specify a card manually as an option. 3) Using "modprobe em18xx card=19" (which corresponds to "EM2860/SAA711X Reference Design") I can go so far as to get a /dev/video0, but the preview is black no matter what i do. 4) I was able to eventually compile the v4l drivers but, as soon as I inject the driver, I get a kernel oops (attached). I made no change to the code obtained with git. I won't even mind to write some code myself, but I really have no idea where to begin with! Thanks in advance for any help you might provide, Best, Mario On 3 January 2012 20:44, Mario Ceresa <mrceresa@xxxxxxxxx> wrote: > Hello everybody! > I recently bougth a Sveon STV40 usb stick to capture analogic video > (http://www.sveon.com/fichaSTV40.html) > I can use it in windows but my linux box (Fedora 16 - > 3.1.6-1.fc16.x86_64 - gcc 4.6.2) can't recognize it. > Is there any way I can fix this? > > These are the results of my investigation so far: > > 1) It is identified by lsusb as an Afatech board (1b80:e309) with an > Empia 2861 chip (from dmesg and windows driver inf file) > 2) I experimented with em28xx because the chipset was empia and with > af9015 because I found that the stv22 was supported > (http://linuxtv.org/wiki/index.php/Afatech_AF9015).
