webcam error - ov511.c: No decompressor available

[Miguel Gaspar]

product: Philips (ov518-based) ToUcam 720k webcam
problem: not working, altough detected correctly.
details: module ov511 is loaded when the camera is plugged in, detected as an ov518 chip, detected and enabled decompressor, but when triyng to fetch data this message shows up in the syslog:
'no decompressor available'.
This issue has popped up in the ubuntu foruns and elsewhere. There is some confusion, because there are different models of philips webcam, several different modules (pwc, ov511) and different versions. There where some issues with pwc and pwcx (?) maintainer, and the kernel people. Also, regarding ov511, I don't understand if it is compiled in the kernel or not, and if it is, what version?
This is a popular webcam, and there are some other manufacturer's models with the same problem.

Here's an extract from syslog:

This issue was found in hoary and in breezy.

Contrary to Ben Collins' status explanation
<quote>This is fixed in dapper, but will not be fixed in breezy.</quote>
, this bug still occurs in dapper, at least in the first beta. I tested with live-cd kubuntu, with the exact same problem.
