** Summary changed: - Webcam (gspca) is not detected anymore since ubuntu 8.10 and Kernel 2.6.27 + Some gspca Webcams not detected in ubuntu 8.10 and Kernel 2.6.27 anymore (for which in 8.04 an alternative driver had to be blacklisted)
** Description changed: - == Regression details == Discovered in version: linux-image-2.6.27-7-generic Last known good version: linux-image-2.6.24-21-generic 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. + v4l2 and thus only with ekiga. (no v4l support in this driver) 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: + Since 8.10 the cam is not detected after blacklisting 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. + Compiling the newest version of gspca using these instructions: http://moinejf.free.fr/gspca_README.txt + does not help immediately. - 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. + 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. -- Some gspca Webcams not detected in ubuntu 8.10 and Kernel 2.6.27 anymore (for which in 8.04 an alternative driver had to be blacklisted) https://bugs.launchpad.net/bugs/293259 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
