I'll do this once I manage to get everything working, just to be sure
it is correct.

I am using kernel 2.4.27, compiled from sources available in the
debian repository.  I recompiled without SCO audio support for hci_usb
and got the same result.

How do I find out what kind of USB host controller I'm using?  lspci
gives the following output:

0000:00:1f.2 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #1) (rev 04)
