I tried changing it to IRQ 9 which is unused, but I still can't access
the card with interrupt-driven I/O.
However, polled I/O does work.
Here's my dmesg output:

And here's the entry in pccard.conf for it:
card "U.S. Robotics" "XJ/CC1560"
config auto "sio1" any
reset 10000
insert logger -s U.S. Robotics XJ/CC1560 Modem inserted
remove logger -s U.S. Robotics XJ/CC1560 Modem removed
What could be the problem?
