Re: [Linux-uvc-devel] Acer HD Crystal webcam detected but cheese doesn't work
Hi All, I was able to fix the webcam issue by upgrading the kernel and installing the libv4l 0.5.7 package from this ppa : https://launchpad.net/~lool/+archive Thanks everyone.

I also have a problem with my headphone for which a patch to alsa base was commited but is still in the svn. So I guess I have to compile ALSA separately apart from libv4l. > Anyway you will probably still > encounter some issue after the upgrade because the libv4l package > included in intrepid has a "nasty" bug (as Hans said) with uvcvideo > webcams.

The kernel package with the fix finally entered intrepid-proposed some days ago (after about two months? still I can't believe how ubuntu folks can be so slow applying serious bugfixes...). Abhishek, you should be able to fix it enabling "proposed" repositories and upgrading the kernel. Anyway you will probably still encounter some issue after the upgrade because the libv4l package included in intrepid has a "nasty" bug (as Hans said) with uvcvideo webcams. It has been fixed in libv4l 0.5.7 and it's already going through a SRU process to get the intrepid package upgraded (http://launchpad.net/bugs/308890). It should enter the proposed repository as soon as someone from the SRU team acknowledges it. If you still have the issue after the kernel upgrade consider installing libv4l 0.5.7 from source because the package might take some time to actually be installable in intrepid.

I compiled uvcview, gspca and cheese from source but still no good. What I did notice is that after recompiling, gstreamer or luvciew doesn't hang anymore like it did before.

They are hardcoded in the driver for known devices, and the module quirks parameter is used to test various quirks for still unsupported devices without requiring the user to patch and recompile the driver. Regarding your original problem, camorama will not work as it doesn't support the V4L2 API. Cheese should work, could you please describe the problem in more details ? Make sure you include application and kernel log messages in your report.

I compiled usbutils from source and attached it as mentioned. It also gave
the following at console:
lsusb -v -d 064e:a117 > lsusb-064e:a117.txt
can't get device qualifier: Operation not permitted
can't get debug descriptor: Operation not permitted
cannot read device status, Operation not permitted (1)

I was trying various workarounds on the net from forums and bug reports. I
don't think it is reqd as I can view it from luvcview and guvcview.
What do we need that quirks param for anyway?
Also, I read
