i just found out: it _is_ a pwc driver problem. pwc-if.c has a line:
pwc_set_agc(pdev, 1, 0);
(which is line 1213 in pwc-10.0.12-rc1) & thank you matju for finding
this.
this line seems to initialize the agc parameter to 'automatic'. i just
commented out this line and now i can use the cam with manual gain
control, even if the app, i am using the cam with, doesn't do any pwc
specific settings.
sorry to doublepost this, but it seems a pretty important solution for
many cases and i wanted to make sure, that for future searches, the
solution will be find in the correct thread.
