Thanks for the data. It's the same as for all my VT6307, excluding
GUID (different for every card) and PCI subsystem vendor/device IDs.

I guess Stefan could now try to write these values (except GUID
and probably PCI subsystem IDs, and with OHCI 1.1 bit) to the "bad"
card :-) I wouldn't try with a good card yet, though (unless you
know how to repair it and/or you want to risk it, and/or you
want to use the DOS utility mentioned by Stefan).

I would try myself but I have no VT6306.

BTW I don't know where I found the info about VT6306 not working
with I^2C EEPROMs but it seems to be false, the datasheets claim
both chips can get startup info from 4-wire or I^2C EEPROM. Given
that both chips have identical EEPROM interface (except "fast I^2C
mode" which means nothing) I'd be surprised if the program can't
set OHCI 1.1 on VT6306.

Yeah. I think (feel or something) VIA does the usual thing with
revision numbers so rev 0x46 means always the same silicon (VT6306)
and rev 0x80 is always the same VT6307. There might be other
revisions but I think we won't find non-VT6306 rev 0x46 or
non-VT6307 rev 0x80.

And, for someone using the old driver, VT6306 should probably have
8/8 IR/IT contexts while VT6307 - 4/8 (the new driver doesn't seem
to show this info and I think VT6306 can be limited to 4 as well).
