Hi Harvey,
Thanks a lot for your report, and sorry you're having problems.

This is a plug-in PCI card, right?

This particular device looks like a bridge, not a USB controller. Can
you collect the complete "lspci -vvvxxx" output (as root) and the
complete dmesg log?
The first step is to figure out whether the PCI core is enumerating
the device. If nothing else works, you could collect the dmesg log
with the card removed, then again with the card installed, and diff
the two. The PCI core prints at least one line for each PCI device it
finds.
