I am new to ubuntu and I have a problem with my webcam and mic built in Dell SP2208WFP monitor. I have installed ubuntu 10.10 and does not recognize or do not get to work. This is the result of lsusb command:

Detect my webcam as OmniVision, look for drivers for the brand, and install the uvc package. At first it worked but after reboot no longer recognize the webcam and mic. Then, uninstall the packages uvc, and I re-installed, and returned to work, but after rebooting stopped working again. I do not know what I can do to fix it. Any suggestions? Thank you very much.

what program you trying the cam in/with
lets see if xawtv sees your cam
look in your package manager for it xawtv
or the software center
and you may try cheese
full name is cheese webcam booth but should be listed as cheese

Because the webcam works under some circumstances..

If you plug the webcam in after booting...does the web cam work ?

You could compare the dmesg & lsmod output for the two use cases you tabled.
Or for post boot webcam plugin.

i.e. what changes between UVC installed fresh & then rebooting ?

AFAIK this kind of behaviour is caused by a device driver grabbing a device it should not.
You can find this in the above std output comparison.
Maybe then a blacklist or rmmod/ismod will allow a fix...

Thank you very much for your answer, but im really new to ubuntu and I dont know what does mean all the information from the dmesg & ismod command. The webcam doesn't work if I plug it after booting. What do i have to look to find what's wrong?

Don't have any further ideas except give up..

It is very strange the webcam worked after uvc install..& the webcam not working when plugged in after reboot.

Sorry.

if you have the driver installed
rerun dmesg

then retry xawtv
