[pwc] VIDIOCPWCGAC error

[Thomas Pfrommer <>]

Hi pwc experts,

we are using the Toucam 740 and are very happy with its performance 
together with the Mandriva 2006 distro. However, occasionally we get the 
error massage
VIDIOCPWCAGC: invalid argument. We can still see the images on qastrocam 
as our frontend, but it writes this error line after line for hours, 
sometimes. And this is what is weird: Not all the time. The newest pwc 
driver 10.0.7a-1mdk for mandriva is installed. Now the puzzling part:
typing setpwc -p gives us the automatic gain control value of some 
negative number, implying the webcam is on auto-mode, what it should be. 
Is it possible that qastrocam is still using an older driver? How could 
i find out and how could I remove an older driver and use the newest 
installed one for all programs?

Thanks for your help!
Thomas
