How's this going? I recently got a Creative Live! Cam Optia (ID 041e:4057) and am using it with motion. Although it's connected to a USB2 port, I'm getting a problem (maybe caused by a bug in the usb root driver, but that's not the topic here¹) that causes the device to disappear if I try to use the full resolution of the camera. As a work-round for that, I thought I could use MJPEG, but then I hit the problem this thread is about. I'm using the latest(?) fedora 9 kernel (2.6.27.23-78.2.50.fc9.x86_64). F9 is a bit out of date now, but looking at the uvcvideo repo I couldn't find signs of the patch having been applied. It would be useful to me if a patch for this did get included. In the short term I suppose I could build a patched version of the module (modulo some change to the patch to make it apply to the present code), but it would be much nicer if it made it into the tree. (Mostly posting to indicate that there is other interest in this issue). [1] I can't address the USB root issue as I'm too far from the camera to unplug it.
