Hi,

Can somebody tell me how is created this device?

When I'm connecting my webcam, nothing happends but in messages.log:

kernel: usb 4-1.4: USB disconnect, address 3
kernel: usb 4-1.4: new full speed USB device using uhci_hcd and address 4
kernel: usb 4-1.4: not running at top speed; connect to a high speed hub
kernel: usb 4-1.4: configuration #1 chosen from 1 choice
kernel: 4:3:1: cannot set freq 0 to ep 0x86
kernel: 4:3:2: cannot set freq 0 to ep 0x86

When I load the module ("modprobe gspca"), new in messages.log:
kernel: usbcore: registered new driver gspca
kernel: /var/tmp/bach-build/BUILD/gspcav1-20060925/gspca_core.c: gspca driver 
01.00.04

And always no /dev/video0

I create it ("mknod /dev/video0 c 81 0; chmod go+wr /dev/video0"), verify

[root@lns-bzn-59-82-252-142-2 ~]# ls -l /dev/video0
crw-rw-rw- 1 root root 81, 0 nov 16 01:45 /dev/video0

and run an application

[root@lns-bzn-59-82-252-142-2 ~]# xawtv
This is xawtv-3.95, running on Linux/i686 (2.6.18-1.2239.fc5)

v4l2: open /dev/video0: Aucun périphérique de ce type
v4l: open /dev/video0: Aucun périphérique de ce type

Where is the problem?

I'm loosing my hair...

Alain
