Как дать ядру понять что у него две платы видеозахвата?

Всем привет. :D
У меня имеется две платы видеозахвата. Одна 4-х канальная с одним чипом bt878, а вторая 8-и канальная имеющая 8 чипов bt878 на борту.
Т.к. ядро само не может определить тип платы я передаю ему его вручную

# modprobe -v bttv card=0x69,0x69,0x69,0x69,0x69,0x69,0x69,0x69,0x69 tuner=-1,-1,-1,-1,-1,-1,-1,-1,-1 autoload=0

и ядро должно подхватить.... Но подхватывает только плату с 8-ю входами:

Подскажите как мне сделать чтобы у меня правильно заработали обе платы? Какие параметры передать ядру?

07.04.2011 12:49 · отредактировано #149005

решили проблему? :)
а то я столкнулся с похожей 4-канальной карточкой и linux видит только 1 канал :(

07.04.2011 16:05 #149072

Проблема оказалась в том, что у одной из плат был мёртвый один из 8 чипов. Вопрос был решён заменой платы поставщиком как бракованной.

Возможно у вас тоже бракованная плата. Попробуйте вставить в windows и посмотреть как она там работает.

08.04.2011 11:11 #149325

ёпрст :( использовать винду не получится - это встраиваемое решение :(
больше никаких варинатов настройки или дров не попадалось?
Спасибо!

08.04.2011 12:50 #149351

Вы не даёте никаких данных (что за карта?, что за устройство?, что за операционка?), а хотите варианты решения. Телепаты в отпуске :D
Дайте вывод, как минимум, команд lspci и dmesg. И тогда можно будет о чём то говорить. И что конкретно за карта у вас.

У вас не правильно определяется устройство.
Почитайте вот эту статью: http://avreg.net/howto_linux-capture-cards.html

08.04.2011 18:07 #149465

спасибо - уже читал :) с modprobe bttv card=.... наигрался, но остальные каналы так и не появились :)
а что посоветуете про изменение параметров видеозахвата? :)
