Also tried opensuse 11.2, also same problem there. Problem: When I start using my webcam, my wifi disconnects and is unable to restart. On the other hand, my webcam only works with wifi disabled. - Those are the components concerned: - Bus 001 Device 003: ID 148f:2573 Ralink Technology, Corp.

RT2501USB Wireless Adapter Bus 001 Device 004: ID 04f2:b022 Chicony Electronics Co., Ltd Gateway USB 2.0 Webcam Workaround: Disabled uvcvideo by blacklisting it. When I want to use my webcam, I need a Cable-LAN connection and starting it manually with sudo modprobe uvcvideo First I thought, this bug is related to bug #435352, but as this seems to be solved with an kernel-update, and mine isn't, it seems to be a new one. In var/log/debug and messages there is no suspicious entry about that. This bug affects all applications that use my webcam (Kopete, Skype, luvcview, etc.) Here's the difference when using luvcview: WIFI disabled: - luvcview 0.2.4 + luvcview 0.2.4 SDL information: - Video driver: x11 - A window manager is available + Video driver: x11 + A window manager is available Device information: - Device path: /dev/video0 + Device path: /dev/video0 Stream settings: - Frame format: YUYV (MJPG is not supported by device) - Frame size: 640x480 - Frame rate: 30 fps + Frame format: YUYV (MJPG is not supported by device) + Frame size: 640x480 + Frame rate: 30 fps Quit signal received.
