Description of problem: webcam fails with "uvcvideo: Failed to query (130) UVC control 2 (unit 2) : -110 (exp. 2)." Version-Release number of selected component (if applicable): kernel 2.6.18-148.el How reproducible: frequent Steps to Reproduce: 1. Connect camera ( 046d:0990 Logitech, Inc. QuickCam Pro 9000 ) 2. Use Ekiga Actual results: webcam stops working Expected results: webcam should work Additional info: Seems to be an issue with ehci scheduler http://osdir.com/ml/linux.drivers.uvc.devel/2008-04/msg00040.html . From http://www.quickcamteam.net/devices http://www.quickcamteam.net/devices/logitech_uvc_device_feature_list_by_device.pdf Customer's device is bcdLevel 7, whereas the device affected in question have 8 . customer has tried workaround mentioned at http://www.quickcamteam.net/documentation/faq/logitech-webcam-linux-usb-incompatibilities. Using "rmmod ehci-hcd" system helps, but reduces the resolution to near-useless but makes Ekiga stable. Alternatively, rebooting system helps. The reset patch was not merged into upstream. Unplugging and plugging device does not help, neither does using different usb ports.

That commit seems to be for hardware that doesn't properly release ISO usb events. I was able to install Ekiga, thanks to Marc's pointer. But of course Ekiga had trouble using my webcam for some reason (bad fonts?). Cheers, Don
Instead of struggling with this issue repeatedly, I took a crack at trying to backport these patches safely. I brought in 4 commits based on the two suggested. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=79592b722e7a8476680197d97352d2cc0f1bffd2 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=b40e43fcc532fa44a375a37d592e32cd0d50fe7a http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=30bf54e62a7926a483b4e36015bb4eb1372e6303 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=9aa09d2f8f4bc440d6db1c3414d4009642875240 Each of the suggested commit had a small dependency on a previous patch (it seemed), so I brought it those too. It compiled and seemed to work fine over here (but I couldn't reproduce the problem). I kicked off a brew build to pass along to the customer. I'll update when it is done. Cheers, Don
