Playstation Eye

Hello,
a few weeks ago I bought a Plaistation Eye (PS3's webcam) to use it on Linux (haven't got a PS3, but that should be the best quality/price webcam around).
It was working fine on 2.6.29-ARCH, but as soon as I upgraded to 2.6.30-ARCH, it stopped working.

I've been quite busy for the last weeks, so chosed to wait for a while, but now I've got some spare time and would like to get it working on the latest kernel...

Google isn't helping me this time, and I couldn't test it on other distributons running 2.6.30...

Here are a few infos about my system...

Anybody has got a ps3 eye, or knows anything about it?

Re: Playstation Eye

Err, no, actually I didn't...

Anyway I'm not so sure the issues are related: it looks like they're using UVC webcams, theirs work with some apps (like kopete or guvcview), while mine is not (i tried skype, kopete, mplayer, vlc, xawtv, luvcview, guvcview, uvcview, cheese and others...), and the errors they're getting are different from mine:

$ luvcview

Re: Playstation Eye

Well, I've got a UVC webcam that works perfectly with linux 2.6.30, but a gspca that doesn't.
So, I think the problem is related.

I'll just wait for a new version of libv4l and/or a new kernel.

Re: Playstation Eye

The problem was not related.
http://patchwork.kernel.org/patch/42114/

The problem has been fixed on Linux 2.6.30.6 (kernel26-2.6.30.6-1 package) and 2.6.31.

Re: Playstation Eye

I have a Hercule Dualpix HD, which uses the same driver. My problem was solved upgrading to kernel 2.6.31, not with the 2.6.30.6.
