If you're getting insertion and removal messages, that's a good
sign. You may have gotten over the IRQ hump.
The "(NULL) (NULL)" messages may be due to a pcic memory conflict.
What does "pccardc dumpcis" display? If you get messages like "code XXX
ignored", where "XXX" is a number, then you may have a memory conflict.

In theory, PCI devices can share IRQs. In practice (in FreeBSD),
it depends. The FreeBSD 4.X pcic device is, alas, special in that it
cannot share IRQs (Warner just verified this). With luck, the USB
device can share IRQs (but I don't know this for a fact).
