[Bug 293259] Re: Webcam (gspca) is not detected anymore since ubuntu 8.10 and Kernel 2.6.27

[Andres Mujica]

OK, you're right.  So this is a regression introduced by 2.6.27 kernel.

Thanks for your input

Can you provide as separate attachments this files:

uname -a > uname-a.log

cat /proc/version_signature > version.log

dmesg > dmesg.log

sudo lspci -vvnn > lspci-vvnn.log

** This bug is no longer a duplicate of bug 260918
   needed: libv4l and associated application patches (or "gspca stopped working in 2.6.27")

** Description changed:

  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.

** Tags added: regression-2.6.27 regression-release

** Changed in: linux (Ubuntu Intrepid)
       Status: New => Confirmed

** Changed in: linux (Ubuntu)
       Status: New => Incomplete
