Trust Spacec@m 120 webcam and motion

[jfheintz]

Hello,

I have a Trust Spacec@m 120 (USB webcam)
I would lik to make it work with motion (http://www.lavrsen.dk/twiki/bin/view/Motion/WebHome)

Having a lookup to the internet show the webcam is supported by gspca driver
(http://mxhaard.free.fr/spca5xx.html)

So I download the driver via yum

# modprobe gspca

Before plug in the webcam, I have a look to /dev

[root]# ls /dev

I plug the webcam

2 entries has appear in /dev
usbdev2.3_ep82
usbdev2.3_ep83

usbdev2.3_ep81 and usbdev2.3_ep00 already exist


Everything sounds good:

Now I launch motion and when I specify

videodevice /dev/usbdev2.3_ep82

motion failed with:
[2] Failed to open video device /dev/usbdev2.3_ep00: No such device or address

Idem for /dev/usbdev2.3_ep00 81 83

Any idea while the device is not recognized?
Most website refers to /dev/video0 or /dev/videodev0, but there is no such entry in /dev
No more entry in /dev/usb

Thanks a lot for your help
