Re: MSI StarCam 370i: The right way?

[Dotan Cohen]

 In the kernel you have (2.6.31) two drivers may try to handle your
 webcam: gspca_sonixj and sn9c102. If both are generated, the active
 driver changes at each webcam unplug/replug (you may know which driver
 is active looking at the last lines of 'dmesg').

 If the driver gspca_sonixj does not work, you may try its last version
 from LinuxTv.org (many bugs have been found since kernel 2.6.31).


Thank you Jean-Francois. Is unplug/replug the only way to switch
drivers? Apparently neither driver works, where is a good place to get
the snc102 driver to try as well? Googling snc102 linux driver did
not lead me to any place to download it.

Thanks!

Using MSI StarCam 370i Webcam with Kubuntu Linux

[Dotan Cohen]

I have the MSI StarCam 370i Webcam and I have trying to use it with
Kubuntu Linux 9.04 Jaunty. According to this page, The StarCam 370i
is compliant with UVC, USB video class:
http://gadgets.softpedia.com/gadgets/Computer-Peripherals/The-MSI-StarCam-370i-3105.html

According to the Linux UVC driver and tools download page, Linux
2.6.26 and newer includes the Linux UVC driver natively which is nice
as I am on a higher version:
$ uname -r
2.6.28-15-generic

However, plugging in the webcam and testing with camorama, cheese, and
luvcview led me to no results:

jaun...@laptop:~$ luvcview -f yuv
luvcview 0.2.4
