Re: My Webcam dosn't work

First of all, the code tags use square brackets like these []. Angle brackets don't do anything on this forum.

Second, I'm slightly confused. You edited /etc/modprode.d/uvcvideo.conf, and added the line "options uvcvideo nodrop=1" (without the quotes), right?

Third, how are you testing the webcam?

To find the model number, you may be able to run "dmesg | grep 090c" or if that doesn't work grep for usb instead.

Re: My Webcam dosn't work

Sorry for beeing redundant but first:

[...]
how you can see, I don't have any information from my webcam.

This IS your webcam, isn't it?

Bus 002 Device 005: ID 090c:37b0 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) 

See here.
Secondly i found this bug report. So the mentioned module option (options uvcvideo nodrop=1) is used to resolve the very same bug on some systems, maybe double check if there's no typos or so in your file (speaking from my own experience )
Sorry again for not bringing up any new information, just wanted to emphasize those two points.

Edit: sorry, didn't realized that you already answered again while i was still editing my post.

Read the wiki. I have no idea what this gst-launch thing you mention is doing, and there are ways to test a webcam that won't freeze Arch. It's on the wiki.
