Micromedia webcam

[Spack]

Hi all,

I've got a Dell Inspiron 1564 with an integrated webcam :

Bus 001 Device 007: ID 0c45:641d Microdia

When I installed my Fedora 13, this webcam used to work very fine. But I
don't know what happened, now I can't get it to work anymore. When I
open cheese, the little webcam's light turns on and shutdown quickly.

My webcam uses the uvcvideo module but I can't see anything wrong in the
logs :

Unless I launch cheese from the terminal in which I get the following
errors :

Quote:
$ cheese
libv4l2: error dequeuing buf: I/O error
libv4l2: error dequeuing buf: I/O error
libv4l2: error dequeuing buf: Invalid argument

So what happened to my webcam which used to work? Maybe an updated
package broke it but I can't tell which one would do that... :s

I tried to load the module with quirks mode or the trace option but none
worked.
