Hallo,
I am using the Philips PCVC 740 with Suse kernel-of-the-day 2.6.13-rc6
and PWC driver 10.0.7a. I get a lot of
of below messages messing up my syslog. I get this messages using
Camstream and Motion. The number of
messages per second is CPU load dependent. If a run motion alone I get
one message per second on the average. If I run motion and compile the
kernel at the same time I get about seven of these messages per second.
Also I realise that the messages become more frequent if the harddisk
becomes active or the framerate in camstream is increased.
However the Camstream and Motion outputs look fine.
Do other people have the same experience?
Is this a PWC driver problem or general USB kernel problem with
isochronous pipes?
