Bug Description

Ever since i upgraded to intrepid my webcam has stopped functioning. This is what i get from dmesg.
[14364.336017] usb 1-5: new full speed USB device using ohci_hcd and address 9
[14364.549071] usb 1-5: configuration #1 chosen from 1 choice
[14364.551712] usb 1-5: ZC0301[P] Image Processor and Control Chip detected (vid/pid 0x0AC8:0x303B)
 [14364.683326] usb 1-5: No supported image sensor detected

Previously it was working fine.
I can use a hardy livecd and my webcam works, and i can use virtualbox with usb passthrough to windows XP

lsusb reports my webcam as

Bus 001 Device 009: ID 0ac8:303b Z-Star Microelectronics Corp. ZC0303 WebCam

the label on the camera says it's an inprime cam-700

I mailed the developer and he said...

Hello,

It seems you generated the zc0301 driver and that your sensor is
not detected. You should modify the v4l/.config and remove the zc0301
driver. I will update the generation options for it will work in the
next kernel (2.6.29).

Best regards.

Hi CShadowRun,

Could you email the developer you spoke with once more and ask if they could provide a reference to the patch that will enable this to work with 2.6.29. Thanks.

@CShadowRun -- this is very likely the same problem (and duplicate) as bug #292086. Could you test the Intrepid kernels at the URL below and report back here:

@CShadowRun -- the fix included in my webcams1 kernels has now hit the -proposed kernels. Can you test if your camera works ok with Ubuntu-2.6.27-11.25 or later from -proposed and report back. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

@CShadowRun -- sorry for the long delay. Looking back at our git tree it seems that the change may not have correctly hit the kernel until Ubuntu-2.6.27-12.28. A later kernel than that is now present in -proposed. Can you confirm if you are seeing this issue still and report here.
