Ahh, the driver is back in the FC kernel. Seems that the version of Luc Saillard ([email protected]) is used.

Hey Luc,
care to pass the physical device down to the videodev registration to let the class driver create the symlink to the physical usb device. This is needed for e.g. HAL (hal.freedesktop.org) to recognize the device.

As an example, here is my old ov511 camera with these links:

[kay@pim linux.kay]$ ls -l /sys/class/video4linux/video0/

  -r--r--r--  1 root root 4096 Nov 21 15:40 bridge
  -r--r--r--  1 root root 4096 Nov 21 15:40 brightness

  -r--r--r--  1 root root 4096 Nov 21 15:40 saturation

Thanks,

That has already been done in newer versions.

$ ls -l /sys/class/video4linux/video0
r--r--r--  1 root root 4096 Nov 21 16:36 dev
lrwxrwxrwx  1 root root    0 Nov 21 16:36 device -> ../../../devices/pci0001:10/0001:10:1b.1/usb3/3-1/
lrwxrwxrwx  1 root root    0 Nov 21 16:36 driver -> ../../../bus/usb/drivers/usb/
-r--r--r--  1 root root 4096 Nov 21 16:36 name

My hal recognizes my pwc cam just fine :)

Sounds good. :)

The FC3 version is:
#define PWC_VERSION "9.0.2-unofficial"

What's your version?

Thanks,

You need >= 10.0.5.. See http://www.saillard.org/pwc/ChangeLog for the details

What's your version?

The last version 10.0.5 add support for sysfs. You can download it at

A new version will be release soon when i'll found times to fix a bug in v4l2 (streaming is not working).
