Subject: How to debug problem with Playstation Eye webcam?
Date: Fri, 28 Aug 2009 14:41:34 -0700
I'm trying to get a Playstation Eye webcam working under a new install of
Fedora 11 and not having much luck.
I'm running a stock Fedora kernel (2.6.29.4).
When I plug in the device, /dev/video0 is created, and the modules
gspca_main and gspca_ov534 are loaded into the kernel.
The device responds to QUERYCAP and other interrogation commands
from user space, but when my test program actually tries to read
the device, I get a multi-second delay, and an eventual
errno of EIO.
I ran v4l-test version 0.19, and some tests succeeded and others failed.
Results are shown below. Note that I had to disable the test
"VIDIOC_G_CTRL with NULL parameter", because that resulted in a hang
of v4l-test when run against the 'Eye' webcam.
A logitech web camera has mixed results from v4l-test as well
(succeeding and failing in different places from the Playstation Eye).
But the logitech works fine with my test program and a variety of
other programs.
I'm not sure where to look next to continue debugging this.
I assume that the general relationship of components is:
test program ->linux kernel -> gspca main driver ->
USB and ov534 driver -> USB and camera hardware
Any tips for how to figure out where the problem might be,
reports of previous experience with this webcam, or additional
diagnostic tools or techniques would be much appreciated.
Thanks,

Hi Tim,
before doing any further investigation about code in 2.6.29.4, forgive
the silly question: is using a more recent kernel/driver an option for
you?
I've just tried latest code from v4l-dvb and it "just works" with the
applications I use. You can get the mercurial repository here
http://linuxtv.org/hg/v4l-dvb
I know that there was a regression in 2.6.30 (not sure about 2.6.29.4)
and a patch has been sent by Jim Paris to fix it, I don't know if it is
already in a 2.6.30.x release, tho. The change is this one:

I'd give a run to _latest_ code to see if the problem has been
solved already, and if you really can't use it, then you isolate the fix
and apply it to the code you have to use.
Captain Obvious to the rescue :)

I believe 2.6.29.4 should be okay. However, the Fedora folks might
have pulled some newer patches which also added the bug. You might
try a stock 2.6.29.4 kernel instead of Fedora's, or just apply the
patch that Antonio refers to (if thta's the problem).
If your kernel does have the same bug, the symptoms would be as you
described, with the camera's red LED turning on during an attempted
capture. Do you get the red LED?
You would also probably see the same problem, regardless of kernel
version, if the camera were connected to a full-speed instead of
high-speed USB port.

Agreed. luvcview is probably the easiest to test with, and I can
provide command lines for mplayer, ffmpeg, etc, if necessary.

Jim and Antonio,
Thanks very much for the suggestions! I got it working with
luvcview! See below for some details.

I found that Fedora 11 did indeed have the code that the patch fixes.
That is, it was using a payload length of 2040 instead of 2048.
I downloaded the fedora kernel source and rebuilt the kernel
with the patch applied.

Yes, I get the red LED.

I checked, and the USB port is high speed and the camera connects
at high speed.

I had 2 test programs. One runs OK and one still hangs (probably
a bug on my part since I'm new with v4l.)
Cheese and luvcview work great.
Thanks very much for your help!
