I have a Z-Star Microelectronics Corp. ZC0303 WebCam
GSPCA-driver: gspca_zc3xx
the camera is detected when the zc0301 driver is loaded, but only with v4l2 and thus only with ekiga. (no v4l support here) In Hardy 8.04 I just blacklisted zc0301 and gspca took over the cam automatically and cam worked flawlessly.
Since 8.10 the cam is not detected after removing zc0301 anymore. Dmesg only gives me:
[29143.996060] usb 2-1: new full speed USB device using uhci_hcd and address 6
[29144.197121] usb 2-1: configuration #1 chosen from 1 choice
I think it is connected with the kernel 2.6.27, and I have found a similar bug at bugzilla.kernel.org:
http://bugzilla.kernel.org/show_bug.cgi?id=11920
I was able to compile the newest version of gspca using these instructions: http://moinejf.free.fr/gspca_README.txt
Still after installing the new drivers the camera is not detected. Thus I don't think that the gspca driver that comes with ubuntu is causing the problem.
I believe it is something with the kernel itself, or the way gspca and v4l are built into the kernel, but as I don't really know how the linux kernel and driver function I don't know what could be wrong. |

Compiling the newest version of gspca using these instructions: http://moinejf.free.fr/gspca_README.txt
does not help immediately.
to solve this problem you have to simply uncheck the zc0301 driver when compiling gspca (see here for instructions: http://moinejf.free.fr/gspca_README.txt) using e.g. make menuconfig. Compiling it with the zc0301 driver was not putting the vend:prod into the gspca module, as described by Moine in the kernel bug report, and so was preventing the gspca driver from detecting the camera. In Hardy 8.04 it was enough to backlist the zc0301 module.
The entry in the bugzilla kernel talks about the sn9c102 driver, that has to be removed, so it seems it applies to more than one model/type of webcams. For sn9c102 the driver has also to be removed when compiling gspca. In both cases it was enough to blacklist the drivers in Hardy.
