Works fine on XP

What's the hang up on this driver web search is full of OLD News about
the m560x driver ??



Hello Phil

It looks that only root and group adm has access to /dev/video0. Your
are a member of the adm group? Did you try this as root?

Thomas





Chmod to 666 /dev/video*

Now xawtv just hangs there, cannot break even with ctrl C, need to kill
it to return to prompt.

xawtv
This is xawtv-3.95.dfsg.1, running on Linux/x86_64 (2.6.20-14-generic)

Chown to my account no diff.

cannot run as root do not have display set for root

Check your kernel log. You might find something interesting there.

Thomas




But what does it all mean ??

Where do I find the "Kernel log" ? I am only familiar with dmesg and syslog.

Outputs from dmseg and syslog that seem related to the webcam after (
insmod and modprobe ) and running xawtv -f

Kernel log: /var/log/kern.log

It looks like the driver does not find a supported sensor and/or the
sensor probe routine has some pointer problems.

Do you know which sensor your cam is using? You might find some
information about the sensor in the Windoz driver (.inf, .reg files or
in the Registry itself).

I am not familiar with the m560x driver. So, I am not a lot of help
here, sorry.
