I found in recent kernel versions, I think somewhere between 2.6.29.3 and 2.6.30.3, pwc_set_shutter_speed regressed. I was able to fix it with this one-line change (drivers/media/video/pwc/pwc-ctrl.c line 755 in 2.6.30.5 source): ret = send_control_msg(pdev, SET_LUM_CTL, SHUTTER_MODE_FORMATTER, &buf, sizeof(buf)); change to ret = send_control_msg(pdev, SET_LUM_CTL, SHUTTER_MODE_FORMATTER, &buf, 1); I hope you find this information useful.
