I have a Labtec Webcam Pro and use it with Ekiga. I upgraded my system some
days ago and now I noticed that it stopped working correctly.
I see the following error messages in /var/log/messages:
--------------
May 23 15:54:13 chrulli
kernel: /home/user/linux-modules-extra-2.6/debian/build/build_i386_none_686_gspca/gspca_core.c:
[spca50x_move_data:1611] ISOC data error: [0] len=0, status=-84
--------------
The error messages are repeated over and over again, just the value in the
brackets and the value of "len" changes.
There is a heavy side-effect: khubd eats up the CPU. It is constantly at 100%.
The whole USB subsystem breaks. Nothing works anymore, no USB flash drives,
no printer (connected via USB), etc.
After unplugging the webcam and rebooting everything works fine (just that I
do not have any working webcam now...)
