Bingo! That was it.  It seems the BIOS defaults for this ASUS P2B
motherboard are to disable "USB IRQ" (under "PNP & PCI Setup")  Duoh!

I now get:
uhci0: interrupting at irq 9
uhci0: USB version 1.0
usb0 at uhci0
uhub0 at usb0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhid0 at uhub0 port 2 configuration 1 interface 2
uhid0: Microsoft Microsoft Digital Sound System 80, rev 1.00/1.00, addr 2, iclass 3/0

So is anyone working on support for the Digital Sound System 80?  I'd be
happy to help, or write code (if I can get tech docs).

Thanks Andrew!
