CardBus bridge and wireless card plugged into it use same IRQ: Correct?
Hi All
Here is the output of lspci -v:
------------------------------------------

_____________________________________________
The above details the fact (or better: I hope it's a fact :) that
"Ralink RT2500" (a wi-fi chip) is connected to the PCMCIA slot
("CardBus bridge") of a Titanium IV ..
Logic might suggest the connector (the "bridge") can/must use the same
interrupt as the wireless card that is connected to the former, but
I'm not sure on it. So if someone with more knowledge could enlighten
me a bit.
Oh yes: And this might be of interest, too:

ra0 is the wi-fi card, as I hope ...
Thanks in anticipation ...
