Hi Linux UVC developers, apologies for spamming this list with an opened berlios bug item (#103031), but the bugs there seem to not get any attention anymore.
This issue is with the built-in Bison web cam in an MSI Wind U100. Once the camera is enabled (via hotkey), the entire USB subsystem is not responding anymore, causing non-detection of freshly attached USB devices and prevents suspending the box. The only fix so far is to blacklist the "uvcvideo" module or to keep the cam disabled (with hotkey). This is with a stable 2.6.31-14-generic kernel on Ubuntu Karmic. A number of related resources: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/435352 contains many user reports. http://marc.info/?l=linux-kernel&m=125541673726384&w=2 a stalled discussion on the LKML with more technical insight https://lists.berlios.de/pipermail/linux-uvc-devel/2009-September/005143.html a stalled discussion on the linux-uvc-devel ML https://lists.berlios.de/pipermail/linux-uvc-devel/2009-September/005143.html is (according to launchpad) the breaking changeset. This is a very unpleasant bug, as it affects the usability of the system a lot and is a regression: Kernel 2.6.28 worked flawless with the webcam. Keep up the good work! Many thanks and again, sorry for cross-posting, Stephan _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
