Webcam not working

Hi! Today I installed a frontech webcam, its a SN9C20x chipset based cam, but cheese didnt detect it. So after google I complied the microdia drivers to build the sn9c20x.ko module. Then according to the documentation I modprobed the v4l2-compat-ioctl32 module and copied the complied moules to the /lib/modules/`uname -r`/kernel/drivers/media/video/usbvideo/ directory(replaced the 'uname -r' with my kernel version) and did a depmod -a. But still the webcam is not detected by cheese or mplayer.
Here's the dmesg o/p when I insert the cam to my usb port:

Linux video capture interface: v2.00
usbcore: registered new interface driver sn9c20x
sn9c20x: SN9C20x USB 2.0 Webcam Driver v2009.04 loaded
usb 2-3: USB disconnect, address 2
usb 2-3: new full speed USB device using ohci_hcd and address 3

what is wrong here?

Re: Webcam not working

While I don't have that webcam, a quick google found this from August 2009, and perhaps it will provide some clues:

It seems to be spot on about native kernel support. My kernel26 2.6.33.3-1 package includes a /lib/modules/2.6.33-ARCH/kernel/drivers/media/video/gspca/gspca_sn9c20x.ko file.

Re: Webcam not working

Well I loaded the gspca_sn9c20x module

lsmod | grep gspca
gspca_sn9c20x          24908  0 
gspca_main             22907  1 gspca_sn9c20x
videodev               39355  1 gspca_main
usbcore               144320  5 gspca_sn9c20x,gspca_main,ohci_hcd,ehci_hcd

but still cheese cant detect it, trying to view it via mplayer it says "/dev/video0 no such file or directory". I heard ubuntu can detect it, but it seems arch cant.

Re: Webcam not working

From this http://nuigroup.com/forums/viewthread/638/ thread I've found out that this cam works with gspca_sonixj module, but even after loading the module the cam is not working mad 
I think I will give up now sad

Re: Webcam not working

As per my knowledge you need to go for latest drivers as per your web cam model and restore it and than adjust the settings.Try it would definately work.
