: Thanks for the quick reply!
Based on what you've provided, here's my current theory of the crime:
(1) The card is inserted.
(2) The bridge somehow thinks it is a X.X V card. It reports this as
2V in the dmesg because I arbitarily assigned numbers to X and Y.
(3) There's two ways this can happen. One: is that new cards have been
released that implement this standard and your bridge is detecting
it, but either the card or bridge fails to implement it
correctly. Two: There is a problem with the bridge's memory
allocation, so the cbb driver is really talking to something
else. Three: the bridge has a bug in detecting X.X V cards and
they should be ignored.
I'm guessing 'Three' is most likely. How's your hacking skills?
