hi,

i have a working image on my panelpc.
then i install manually the usb webcam driver - all works fine...
but after reboot, the webcam is like frozen...just every 30-45 seconds a
frame :(
the same problem with a diffrent webcam (another brand)...

no events in the eventlog...

what could i do?
why it´s just working till i reboot?
are there any tools where i could figure the error out?
i am using a owned embedded studio SP2

hope you could help
 
Zabby,

The stock answer would be to try running filemon and regmon when using the
webcam after a reboot. Save the log files from these applcations and look
for files and registry data trying to be accessed by your webcam
application. It may help.

Here are some links to the utilities:
Filemon:

Regmon:

Hopefully that will get you started. Post the logs (or relevant information
from the logs) back here for additional help. Also, if you find that in
filemon a NOTFOUND result is coming from files that look useful to the
webcam application you can create a filter in Target Designer to look for
that specific file and it's owning component. For information on creating
filters look here:
