Hi, I'm using Kubuntu 9.10, tried Kubuntu 10.04, same problem there. 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
SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video0
Stream settings:
Frame format: YUYV (MJPG is not supported by device)
Frame size: 640x480
Frame rate: 30 fps
Quit signal received.
Cleanup done. Exiting ...
WIFI enabled:
luvcview 0.2.4
SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video0
ERROR opening V4L interface: Cannot send after transport endpoint shutdown
