aforehand you told me i was forcing it to find an msp3400 in my modules and
that's why it found the msp chip. i said i wasn't, i was using it compiled
in as defaults and i didn't even have a modules conf file.

it worked until now, always showing up as a MIRO but that being aside, let's
start again:

according to the source, it should correctly auto detect, snippits:

/* card type (see bttv.h) 0=autodetect */
#define CARD_DEFAULT 0

static unsigned int card[BTTV_MAX] = { CARD_DEFAULT, CARD_DEFAULT,

/* Default the card to the user-selected one. */
btv->tuner_type=-1; /* use default tuner type */

/* If we were asked to auto-detect, then do so!
Right now this will only recognize Miro, Hauppauge or STB
if (btv->type == BTTV_UNKNOWN)

(unknown defined as 0x0)

i added a few printks to show what some of these critters are

Midnight kernel: returned (idcard:0)

that being the value of i.

so card[i] having a 0 for it's value should auto detect.

the test for the card type at bttv.c:2872 appears to break because it thinks
it finds an msp3400 chip and sets my card type to a MIRO. a couple of
kernels back, it figured it was a MIRO PRO for one patch revision.

now the chips on my board say stb and tda. it finds the tda9850 chip
correctly, then later thinks it has an msp3400 on it.

i don't have the time at the moment to spend a couple days playing with the
driver, but i can compile a new kern with this as modular and include the
debugging with which i can post relevant figures to anyone interested.

i'd love to fix this frustration for once and all but every moment i get a
spare minute to work on something of this like, another issue (in life)
always seems to spring forth :(
