Henrique,

I have a dv2120us, with mic and webcam just like you. Got the SUSE 10.2 installed and updated. Webcam is a Sonix.

Used svn to get the UVC driver and installed it:

svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
cd trunk
make (as root)
make install (as root)
modprobe uvcvideo

Now I got /dev/video pointing to /dev/video0 and dmesg shows the following:

usb 1-8: new high speed USB device using ehci_hcd and address 3
usb 1-8: new device found, idVendor=0c45, idProduct=62c0
usb 1-8: new device strings: Mfr=2, Product=1, SerialNumber=3
usb 1-8: Product: USB 2.0 Camera
usb 1-8: Manufacturer: Sonix Technology Co., Ltd.
usb 1-8: SerialNumber: SN0001
usb 1-8: configuration #1 chosen from 1 choice
Linux video capture interface: v2.00
uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0)
usbcore: registered new driver uvcvideo
USB Video Class driver (v0.1.0)

pretty much like your case, and lsmod shows:

Module Size Used by
uvcvideo 60036 0
videodev 42624 1 uvcvideo
v4l1_compat 28548 2 uvcvideo,videodev
v4l2_common 41472 2 uvcvideo,videodev
usbcore 148064 5 usbhid,uvcvideo,ehci_hcd,ohci_hcd,ndiswrapper

Anyway, the cam does not work. Videoview does not detect it and dmesg shows the following:

ioctl32(videoview:5550): Unknown cmd fd(4) cmd(80685600){00} arg(ffc0f688) on /dev/video0

The interesting thing is that kopete detected the webcam, after doing the "modprobe uvcvideo", but it doesn't work anyway.
I'm included in the audio and video groups.

So I don't understand why it isn't working, as it is the same cam, same driver and same OS. Any idea??
