Well, that means we know what the problem is, AND I have a fix. 1) Grab version 1.64 of the Bt848 driver from my Web Site at http://telepresence.dmem.strath.ac.uk/bt848 2) Locate this part of the brooktree848.c file { CARD_INTEL, /* the card id */ "Intel Smart Video III/VideoLogic Captivator PCI", /* the 'name' */ NULL, /* the tuner */ 0, /* the tuner i2c address */ 0, 0, 0, 0, { 0, 0, 0, 0, 0 }, /* audio MUX values */ 0x0f }, /* GPIO mask */ ** And change the 0x0f on the LAST line to 0x00 Then make a new kernel and try it again (with /dev/tuner being opened) I bet the Camera's power on/off is controlled from the GPIO lines and the driver is currently setting the bottom 4 GPIO lines to OUTPUTS every time you open /dev/tuner. Changing 0x0f to 0x00 makes the driver set all 24 GPIO lines to INPUT mode. (GPIO - general purpose IO. The bt848 has 24 digital i/o lines for interfacing to other devices on the bt848 card) Bye Roger -- Roger Hardiman Strathclyde Uni Telepresence Research Group, Glasgow, Scotland. http://telepresence.dmem.strath.ac.uk 0141 548 2897 roger@cs.strath.ac.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
