What is the significance of this message?
b2c2-flexcop: i2c master_xfer failed
I see it several times while booting with three (two different) video capture
cards.
Right off, it doesnt look good.
Here is (what appears to be) the complete set of messages during the boot:

Im not sure exactly which messages go with the initialization of which card,
but
have tried to split the output (with blank lines) where it seems appropriate.
The 'default' set of i2c devices are set in the kernel, do more need (which
ones)
to be set?
